Introduction

A test library for string manipulation and verification.

String is Robot Framework's standard library for manipulating strings (e.g. Replace String Using Regexp, Split To Lines) and verifying their contents (e.g. Should Be String).

Following keywords from BuiltIn library can also be used with strings:

• Catenate
• Get Length
• Length Should Be
• Should (Not) Be Empty
• Should (Not) Be Equal (As Strings/Integers/Numbers)
• Should (Not) Match (Regexp)
• Should (Not) Contain
• Should (Not) Start With
• Should (Not) End With
• Convert To String
• Convert To Bytes

Keywords

Keyword	Arguments	Documentation
Convert To Lowercase	string	Converts string to lowercase. Examples: ${str1} = Convert To Lowercase ABC ${str2} = Convert To Lowercase 1A2c3D Should Be Equal ${str1} abc Should Be Equal ${str2} 1a2c3d New in Robot Framework 2.8.6.
Convert To Uppercase	string	Converts string to uppercase. Examples: ${str1} = Convert To Uppercase abc ${str2} = Convert To Uppercase 1a2C3d Should Be Equal ${str1} ABC Should Be Equal ${str2} 1A2C3D New in Robot Framework 2.8.6.
Decode Bytes To String	bytes, encoding,errors=strict	Decodes the given bytes to a Unicode string using the given encoding. errors argument controls what to do if decoding some bytes fails. All values accepted by decode method in Python are valid, but in practice the following values are most useful: strict: fail if characters cannot be decoded (default) ignore: ignore characters that cannot be decoded replace: replace characters that cannot be decoded with a replacement character Examples: ${string} = Decode Bytes To String ${bytes} UTF-8   ${string} = Decode Bytes To String ${bytes} ASCII errors=ignore Use Encode String To Bytes if you need to convert Unicode strings to byte strings, and Convert To String in BuiltIn if you need to convert arbitrary objects to Unicode strings.
Encode String To Bytes	string, encoding,errors=strict	Encodes the given Unicode string to bytes using the given encoding. errors argument controls what to do if encoding some characters fails. All values accepted by encode method in Python are valid, but in practice the following values are most useful: strict: fail if characters cannot be encoded (default) ignore: ignore characters that cannot be encoded replace: replace characters that cannot be encoded with a replacement character Examples: ${bytes} = Encode String To Bytes ${string} UTF-8   ${bytes} = Encode String To Bytes ${string} ASCII errors=ignore Use Convert To Bytes in BuiltIn if you want to create bytes based on character or integer sequences. Use Decode Bytes To String if you need to convert byte strings to Unicode strings and Convert To String in BuiltIn if you need to convert arbitrary objects to Unicode.
Fetch From Left	string, marker	Returns contents of the string before the first occurrence of marker. If the marker is not found, whole string is returned. See also Fetch From Right, Split String and Split String From Right.
Fetch From Right	string, marker	Returns contents of the string after the last occurrence of marker. If the marker is not found, whole string is returned. See also Fetch From Left, Split String and Split String From Right.
Generate Random String	length=8, chars=[LETTERS][NUMBERS]	Generates a string with a desired length from the given chars. The population sequence chars contains the characters to use when generating the random string. It can contain any characters, and it is possible to use special markers explained in the table below: Marker Explanation [LOWER] Lowercase ASCII characters from a to z. [UPPER] Uppercase ASCII characters from A to Z. [LETTERS] Lowercase and uppercase ASCII characters. [NUMBERS] Numbers from 0 to 9. Examples: ${ret} = Generate Random String     ${low} = Generate Random String 12 [LOWER] ${bin} = Generate Random String 8 01 ${hex} = Generate Random String 4 [NUMBERS]abcdef
Get Line	string, line_number	Returns the specified line from the given string. Line numbering starts from 0 and it is possible to use negative indices to refer to lines from the end. The line is returned without the newline character. Examples: ${first} = Get Line ${string} 0 ${2nd last} = Get Line ${string} -2 Use Split To Lines if all lines are needed.
Get Line Count	string	Returns and logs the number of lines in the given string.
Get Lines Containing String	string, pattern,case_insensitive=False	Returns lines of the given string that contain the pattern. The pattern is always considered to be a normal string, not a glob or regexp pattern. A line matches if the pattern is found anywhere on it. The match is case-sensitive by default, but giving case_insensitive a true value makes it case-insensitive. The value is considered true if it is a non-empty string that is not equal to false, none or no. If the value is not a string, its truth value is got directly in Python. Considering none false is new in RF 3.0.3. Lines are returned as one string catenated back together with newlines. Possible trailing newline is never returned. The number of matching lines is automatically logged. Examples: ${lines} = Get Lines Containing String ${result} An example   ${ret} = Get Lines Containing String ${ret} FAIL case-insensitive See Get Lines Matching Pattern and Get Lines Matching Regexp if you need more complex pattern matching.
Get Lines Matching Pattern	string, pattern,case_insensitive=False	Returns lines of the given string that match the pattern. The pattern is a glob pattern where: * matches everything ? matches any single character [chars] matches any character inside square brackets (e.g. [abc] matches either a, b or c) [!chars] matches any character not inside square brackets A line matches only if it matches the pattern fully. The match is case-sensitive by default, but giving case_insensitive a true value makes it case-insensitive. The value is considered true if it is a non-empty string that is not equal to false, none or no. If the value is not a string, its truth value is got directly in Python. Considering none false is new in RF 3.0.3. Lines are returned as one string catenated back together with newlines. Possible trailing newline is never returned. The number of matching lines is automatically logged. Examples: ${lines} = Get Lines Matching Pattern ${result} Wild???? example   ${ret} = Get Lines Matching Pattern ${ret} FAIL: * case_insensitive=true See Get Lines Matching Regexp if you need more complex patterns and Get Lines Containing String if searching literal strings is enough.
Get Lines Matching Regexp	string, pattern,partial_match=False	Returns lines of the given string that match the regexp pattern. See BuiltIn.Should Match Regexp for more information about Python regular expression syntax in general and how to use it in Robot Framework test data in particular. By default lines match only if they match the pattern fully, but partial matching can be enabled by giving the partial_match argument a true value. The value is considered true if it is a non-empty string that is not equal to false, none or no. If the value is not a string, its truth value is got directly in Python. Considering none false is new in RF 3.0.3. If the pattern is empty, it matches only empty lines by default. When partial matching is enabled, empty pattern matches all lines. Notice that to make the match case-insensitive, you need to prefix the pattern with case-insensitive flag (?i). Lines are returned as one string concatenated back together with newlines. Possible trailing newline is never returned. The number of matching lines is automatically logged. Examples: ${lines} = Get Lines Matching Regexp ${result} Reg\\w{3} example   ${lines} = Get Lines Matching Regexp ${result} Reg\\w{3} example partial_match=true ${ret} = Get Lines Matching Regexp ${ret} (?i)FAIL: .*   See Get Lines Matching Pattern and Get Lines Containing String if you do not need full regular expression powers (and complexity). partial_match argument is new in Robot Framework 2.9. In earlier versions exact match was always required.
Get Regexp Matches	string, pattern,*groups	Returns a list of all non-overlapping matches in the given string. string is the string to find matches from and pattern is the regular expression. See BuiltIn.Should Match Regexp for more information about Python regular expression syntax in general and how to use it in Robot Framework test data in particular. If no groups are used, the returned list contains full matches. If one group is used, the list contains only contents of that group. If multiple groups are used, the list contains tuples that contain individual group contents. All groups can be given as indexes (starting from 1) and named groups also as names. Examples: ${no match} = Get Regexp Matches the string xxx     ${matches} = Get Regexp Matches the string t..     ${one group} = Get Regexp Matches the string t(..) 1   ${named group} = Get Regexp Matches the string t(?P<name>..) name   ${two groups} = Get Regexp Matches the string t(.)(.) 1 2 => ${no match} = [] ${matches} = ['the', 'tri'] ${one group} = ['he', 'ri'] ${named group} = ['he', 'ri'] ${two groups} = [('h', 'e'), ('r', 'i')] New in Robot Framework 2.9.
Get Substring	string, start,end=None	Returns a substring from start index to end index. The start index is inclusive and end is exclusive. Indexing starts from 0, and it is possible to use negative indices to refer to characters from the end. Examples: ${ignore first} = Get Substring ${string} 1   ${ignore last} = Get Substring ${string}   -1 ${5th to 10th} = Get Substring ${string} 4 10 ${first two} = Get Substring ${string}   1 ${last two} = Get Substring ${string} -2
Remove String	string, *removables	Removes all removables from the given string. removables are used as literal strings. Each removable will be matched to a temporary string from which preceding removables have been already removed. See second example below. Use Remove String Using Regexp if more powerful pattern matching is needed. If only a certain number of matches should be removed, Replace String or Replace String Using Regexp can be used. A modified version of the string is returned and the original string is not altered. Examples: ${str} = Remove String Robot Framework work   Should Be Equal ${str} Robot Frame     ${str} = Remove String Robot Framework o bt Should Be Equal ${str} R Framewrk     New in Robot Framework 2.8.2.
Remove String Using Regexp	string, *patterns	Removes patterns from the given string. This keyword is otherwise identical to Remove String, but the patterns to search for are considered to be a regular expression. See Replace String Using Regexp for more information about the regular expression syntax. That keyword can also be used if there is a need to remove only a certain number of occurrences. New in Robot Framework 2.8.2.
Replace String	string, search_for,replace_with,count=-1	Replaces search_for in the given string with replace_with. search_for is used as a literal string. See Replace String Using Regexp if more powerful pattern matching is needed. If you need to just remove a string see Remove String. If the optional argument count is given, only that many occurrences from left are replaced. Negative count means that all occurrences are replaced (default behaviour) and zero means that nothing is done. A modified version of the string is returned and the original string is not altered. Examples: ${str} = Replace String Hello, world! world tellus   Should Be Equal ${str} Hello, tellus!       ${str} = Replace String Hello, world! l ${EMPTY} count=1 Should Be Equal ${str} Helo, world!
Replace String Using Regexp	string, pattern,replace_with,count=-1	Replaces pattern in the given string with replace_with. This keyword is otherwise identical to Replace String, but the pattern to search for is considered to be a regular expression. See BuiltIn.Should Match Regexp for more information about Python regular expression syntax in general and how to use it in Robot Framework test data in particular. If you need to just remove a string see Remove String Using Regexp. Examples: ${str} = Replace String Using Regexp ${str} 20\\d\\d-\\d\\d-\\d\\d <DATE>   ${str} = Replace String Using Regexp ${str} (Hello|Hi) ${EMPTY} count=1
Should Be Byte String	item, msg=None	Fails if the given item is not a byte string. Use Should Be Unicode String if you want to verify the item is a Unicode string, or Should Be String if both Unicode and byte strings are fine. See Should Be String for more details about Unicode strings and byte strings. The default error message can be overridden with the optional msg argument.
Should Be Lowercase	string, msg=None	Fails if the given string is not in lowercase. For example, 'string' and 'with specials!' would pass, and 'String', '' and ' ' would fail. The default error message can be overridden with the optional msg argument. See also Should Be Uppercase and Should Be Titlecase.
Should Be String	item, msg=None	Fails if the given item is not a string. With Python 2, except with IronPython, this keyword passes regardless is the item a Unicode string or a byte string. Use Should Be Unicode String or Should Be Byte String if you want to restrict the string type. Notice that with Python 2, except with IronPython, 'string' creates a byte string and u'unicode' must be used to create a Unicode string. With Python 3 and IronPython, this keyword passes if the string is a Unicode string but fails if it is bytes. Notice that with both Python 3 and IronPython, 'string' creates a Unicode string, and b'bytes' must be used to create a byte string. The default error message can be overridden with the optional msg argument.
Should Be Titlecase	string, msg=None	Fails if given string is not title. string is a titlecased string if there is at least one character in it, uppercase characters only follow uncased characters and lowercase characters only cased ones. For example, 'This Is Title' would pass, and 'Word In UPPER', 'Word In lower', '' and ' ' would fail. The default error message can be overridden with the optional msg argument. See also Should Be Uppercase and Should Be Lowercase.
Should Be Unicode String	item, msg=None	Fails if the given item is not a Unicode string. Use Should Be Byte String if you want to verify the item is a byte string, or Should Be String if both Unicode and byte strings are fine. See Should Be String for more details about Unicode strings and byte strings. The default error message can be overridden with the optional msg argument.
Should Be Uppercase	string, msg=None	Fails if the given string is not in uppercase. For example, 'STRING' and 'WITH SPECIALS!' would pass, and 'String', '' and ' ' would fail. The default error message can be overridden with the optional msg argument. See also Should Be Titlecase and Should Be Lowercase.
Should Not Be String	item, msg=None	Fails if the given item is a string. See Should Be String for more details about Unicode strings and byte strings. The default error message can be overridden with the optional msg argument.
Split String	string,separator=None,max_split=-1	Splits the string using separator as a delimiter string. If a separator is not given, any whitespace string is a separator. In that case also possible consecutive whitespace as well as leading and trailing whitespace is ignored. Split words are returned as a list. If the optional max_split is given, at most max_split splits are done, and the returned list will have maximum max_split + 1 elements. Examples: @{words} = Split String ${string}       @{words} = Split String ${string} ,${SPACE}     ${pre} ${post} = Split String ${string} :: 1 See Split String From Right if you want to start splitting from right, and Fetch From Left and Fetch From Right if you only want to get first/last part of the string.
Split String From Right	string,separator=None,max_split=-1	Splits the string using separator starting from right. Same as Split String, but splitting is started from right. This has an effect only when max_split is given. Examples: ${first} ${rest} = Split String ${string} - 1 ${rest} ${last} = Split String From Right ${string} - 1
Split String To Characters	string	Splits the given string to characters. Example: @{characters} = Split String To Characters ${string}
Split To Lines	string, start=0,end=None	Splits the given string to lines. It is possible to get only a selection of lines from start to end so that start index is inclusive and end is exclusive. Line numbering starts from 0, and it is possible to use negative indices to refer to lines from the end. Lines are returned without the newlines. The number of returned lines is automatically logged. Examples: @{lines} = Split To Lines ${manylines}     @{ignore first} = Split To Lines ${manylines} 1   @{ignore last} = Split To Lines ${manylines}   -1 @{5th to 10th} = Split To Lines ${manylines} 4 10 @{first two} = Split To Lines ${manylines}   1 @{last two} = Split To Lines ${manylines} -2   Use Get Line if you only need to get a single line.
Strip String	string, mode=both,characters=None	Remove leading and/or trailing whitespaces from the given string. mode is either left to remove leading characters, right to remove trailing characters, both (default) to remove the characters from both sides of the string or none to return the unmodified string. If the optional characters is given, it must be a string and the characters in the string will be stripped in the string. Please note, that this is not a substring to be removed but a list of characters, see the example below. Examples: ${stripped}= Strip String ${SPACE}Hello${SPACE}   Should Be Equal ${stripped} Hello   ${stripped}= Strip String ${SPACE}Hello${SPACE} mode=left Should Be Equal ${stripped} Hello${SPACE}   ${stripped}= Strip String aabaHelloeee characters=abe Should Be Equal ${stripped} Hello   New in Robot Framework 3.0.

将字节解码为字符串	bytes， encoding，errors = strict	使用给定的解码将给定bytes的Unicode字符串解码encoding。 errors如果解码某些字节失败，参数控制该怎么做。decodePython中方法接受的所有值都是有效的，但实际上以下值最有用： strict：如果无法解码字符，则失败（默认） ignore：忽略无法解码的字符 replace：替换无法使用替换字符解码的字符 例子： $ {string} = 将字节解码为字符串 $ {}字节 UTF-8   $ {string} = 将字节解码为字符串 $ {}字节 ASCII 错误=忽略 如果需要将Unicode字符串转换为字节字符串，请使用Encode String To Bytes;如果需要将任意对象转换为 Unicode字符串，请使用Convert To String in BuiltIn。
将字符串编码为字节	字符串， 编码， 错误=严格	string使用给定的代码将给定的Unicode编码为字节encoding。 errors参数控制在编码某些字符失败时如何处理。encodePython中方法接受的所有值都是有效的，但实际上以下值最有用： strict：如果无法编码字符，则失败（默认） ignore：忽略无法编码的字符 replace：替换无法使用替换字符编码的字符 例子： $ {bytes} = 将字符串编码为字节 $ {}字符串 UTF-8   $ {bytes} = 将字符串编码为字节 $ {}字符串 ASCII 错误=忽略 Use Convert To Bytes in BuiltIn if you want to create bytes based on character or integer sequences. Use Decode Bytes To String if you need to convert byte strings to Unicode strings and Convert To String in BuiltIn if you need to convert arbitrary objects to Unicode.
Fetch From Left	string, marker	Returns contents of the string before the first occurrence of marker. If the marker is not found, whole string is returned. See also Fetch From Right, Split String and Split String From Right.
Fetch From Right	string, marker	Returns contents of the string after the last occurrence of marker. If the marker is not found, whole string is returned. See also Fetch From Left, Split String and Split String From Right.
Generate Random String	length=8, chars=[LETTERS][NUMBERS]	Generates a string with a desired length from the given chars. The population sequence chars contains the characters to use when generating the random string. It can contain any characters, and it is possible to use special markers explained in the table below: Marker Explanation [LOWER] Lowercase ASCII characters from a to z. [UPPER] Uppercase ASCII characters from A to Z. [LETTERS] Lowercase and uppercase ASCII characters. [NUMBERS] Numbers from 0 to 9. Examples: ${ret} = Generate Random String     ${low} = Generate Random String 12 [LOWER] ${bin} = Generate Random String 8 01 ${hex} = Generate Random String 4 [NUMBERS]abcdef
Get Line	string, line_number	Returns the specified line from the given string. Line numbering starts from 0 and it is possible to use negative indices to refer to lines from the end. The line is returned without the newline character. Examples: ${first} = Get Line ${string} 0 ${2nd last} = Get Line ${string} -2 Use Split To Lines if all lines are needed.
Get Line Count	string	Returns and logs the number of lines in the given string.
Get Lines Containing String	string, pattern,case_insensitive=False	Returns lines of the given string that contain the pattern. The pattern is always considered to be a normal string, not a glob or regexp pattern. A line matches if the pattern is found anywhere on it. The match is case-sensitive by default, but giving case_insensitive a true value makes it case-insensitive. The value is considered true if it is a non-empty string that is not equal to false, none or no. If the value is not a string, its truth value is got directly in Python. Considering none false is new in RF 3.0.3. Lines are returned as one string catenated back together with newlines. Possible trailing newline is never returned. The number of matching lines is automatically logged. Examples: ${lines} = Get Lines Containing String ${result} An example   ${ret} = Get Lines Containing String ${ret} FAIL case-insensitive See Get Lines Matching Pattern and Get Lines Matching Regexp if you need more complex pattern matching.
Get Lines Matching Pattern	string, pattern,case_insensitive=False	Returns lines of the given string that match the pattern. The pattern is a glob pattern where: * matches everything ? matches any single character [chars] matches any character inside square brackets (e.g. [abc] matches either a, b or c) [!chars] matches any character not inside square brackets A line matches only if it matches the pattern fully. The match is case-sensitive by default, but giving case_insensitive a true value makes it case-insensitive. The value is considered true if it is a non-empty string that is not equal to false, none or no. If the value is not a string, its truth value is got directly in Python. Considering none false is new in RF 3.0.3. Lines are returned as one string catenated back together with newlines. Possible trailing newline is never returned. The number of matching lines is automatically logged. Examples: ${lines} = Get Lines Matching Pattern ${result} Wild???? example   ${ret} = Get Lines Matching Pattern ${ret} FAIL: * case_insensitive=true See Get Lines Matching Regexp if you need more complex patterns and Get Lines Containing String if searching literal strings is enough.
Get Lines Matching Regexp	string, pattern,partial_match=False	Returns lines of the given string that match the regexp pattern. See BuiltIn.Should Match Regexp for more information about Python regular expression syntax in general and how to use it in Robot Framework test data in particular. By default lines match only if they match the pattern fully, but partial matching can be enabled by giving the partial_match argument a true value. The value is considered true if it is a non-empty string that is not equal to false, none or no. If the value is not a string, its truth value is got directly in Python. Considering none false is new in RF 3.0.3. If the pattern is empty, it matches only empty lines by default. When partial matching is enabled, empty pattern matches all lines. Notice that to make the match case-insensitive, you need to prefix the pattern with case-insensitive flag (?i). Lines are returned as one string concatenated back together with newlines. Possible trailing newline is never returned. The number of matching lines is automatically logged. Examples: ${lines} = Get Lines Matching Regexp ${result} Reg\\w{3} example   ${lines} = Get Lines Matching Regexp ${result} Reg\\w{3} example partial_match=true ${ret} = Get Lines Matching Regexp ${ret} (?i)FAIL: .*   See Get Lines Matching Pattern and Get Lines Containing String if you do not need full regular expression powers (and complexity). partial_match argument is new in Robot Framework 2.9. In earlier versions exact match was always required.
Get Regexp Matches	string, pattern,*groups	Returns a list of all non-overlapping matches in the given string. string is the string to find matches from and pattern is the regular expression. See BuiltIn.Should Match Regexp for more information about Python regular expression syntax in general and how to use it in Robot Framework test data in particular. If no groups are used, the returned list contains full matches. If one group is used, the list contains only contents of that group. If multiple groups are used, the list contains tuples that contain individual group contents. All groups can be given as indexes (starting from 1) and named groups also as names. Examples: ${no match} = Get Regexp Matches the string xxx     ${matches} = Get Regexp Matches the string t..     ${one group} = Get Regexp Matches the string t(..) 1   ${named group} = Get Regexp Matches the string t(?P<name>..) name   ${two groups} = Get Regexp Matches the string t(.)(.) 1 2 => ${no match} = [] ${matches} = ['the', 'tri'] ${one group} = ['he', 'ri'] ${named group} = ['he', 'ri'] ${two groups} = [('h', 'e'), ('r', 'i')] New in Robot Framework 2.9.
Get Substring	string, start,end=None	Returns a substring from start index to end index. The start index is inclusive and end is exclusive. Indexing starts from 0, and it is possible to use negative indices to refer to characters from the end. Examples: ${ignore first} = Get Substring ${string} 1   ${ignore last} = Get Substring ${string}   -1 ${5th to 10th} = Get Substring ${string} 4 10 ${first two} = Get Substring ${string}   1 ${last two} = Get Substring ${string} -2
Remove String	string, *removables	Removes all removables from the given string. removables are used as literal strings. Each removable will be matched to a temporary string from which preceding removables have been already removed. See second example below. Use Remove String Using Regexp if more powerful pattern matching is needed. If only a certain number of matches should be removed, Replace String or Replace String Using Regexp can be used. A modified version of the string is returned and the original string is not altered. Examples: ${str} = Remove String Robot Framework work   Should Be Equal ${str} Robot Frame     ${str} = Remove String Robot Framework o bt Should Be Equal ${str} R Framewrk     New in Robot Framework 2.8.2.
Remove String Using Regexp	string, *patterns	Removes patterns from the given string. This keyword is otherwise identical to Remove String, but the patterns to search for are considered to be a regular expression. See Replace String Using Regexp for more information about the regular expression syntax. That keyword can also be used if there is a need to remove only a certain number of occurrences. New in Robot Framework 2.8.2.
Replace String	string, search_for,replace_with,count=-1	Replaces search_for in the given string with replace_with. search_for is used as a literal string. See Replace String Using Regexp if more powerful pattern matching is needed. If you need to just remove a string see Remove String. If the optional argument count is given, only that many occurrences from left are replaced. Negative count means that all occurrences are replaced (default behaviour) and zero means that nothing is done. A modified version of the string is returned and the original string is not altered. Examples: ${str} = Replace String Hello, world! world tellus   Should Be Equal ${str} Hello, tellus!       ${str} = Replace String Hello, world! l ${EMPTY} count=1 Should Be Equal ${str} Helo, world!
Replace String Using Regexp	string, pattern,replace_with,count=-1	Replaces pattern in the given string with replace_with. This keyword is otherwise identical to Replace String, but the pattern to search for is considered to be a regular expression. See BuiltIn.Should Match Regexp for more information about Python regular expression syntax in general and how to use it in Robot Framework test data in particular. If you need to just remove a string see Remove String Using Regexp. Examples: ${str} = Replace String Using Regexp ${str} 20\\d\\d-\\d\\d-\\d\\d <DATE>   ${str} = Replace String Using Regexp ${str} (Hello|Hi) ${EMPTY} count=1
Should Be Byte String	item, msg=None	Fails if the given item is not a byte string. Use Should Be Unicode String if you want to verify the item is a Unicode string, or Should Be String if both Unicode and byte strings are fine. See Should Be String for more details about Unicode strings and byte strings. The default error message can be overridden with the optional msg argument.
Should Be Lowercase	string, msg=None	Fails if the given string is not in lowercase. For example, 'string' and 'with specials!' would pass, and 'String', '' and ' ' would fail. The default error message can be overridden with the optional msg argument. See also Should Be Uppercase and Should Be Titlecase.
Should Be String	item, msg=None	Fails if the given item is not a string. With Python 2, except with IronPython, this keyword passes regardless is the item a Unicode string or a byte string. Use Should Be Unicode String or Should Be Byte String if you want to restrict the string type. Notice that with Python 2, except with IronPython, 'string' creates a byte string and u'unicode' must be used to create a Unicode string. With Python 3 and IronPython, this keyword passes if the string is a Unicode string but fails if it is bytes. Notice that with both Python 3 and IronPython, 'string' creates a Unicode string, and b'bytes' must be used to create a byte string. The default error message can be overridden with the optional msg argument.
Should Be Titlecase	string, msg=None	Fails if given string is not title. string is a titlecased string if there is at least one character in it, uppercase characters only follow uncased characters and lowercase characters only cased ones. For example, 'This Is Title' would pass, and 'Word In UPPER', 'Word In lower', '' and ' ' would fail. The default error message can be overridden with the optional msg argument. See also Should Be Uppercase and Should Be Lowercase.
Should Be Unicode String	item, msg=None	Fails if the given item is not a Unicode string. Use Should Be Byte String if you want to verify the item is a byte string, or Should Be String if both Unicode and byte strings are fine. See Should Be String for more details about Unicode strings and byte strings. The default error message can be overridden with the optional msg argument.
Should Be Uppercase	string, msg=None	Fails if the given string is not in uppercase. For example, 'STRING' and 'WITH SPECIALS!' would pass, and 'String', '' and ' ' would fail. The default error message can be overridden with the optional msg argument. See also Should Be Titlecase and Should Be Lowercase.
Should Not Be String	item, msg=None	Fails if the given item is a string. See Should Be String for more details about Unicode strings and byte strings. The default error message can be overridden with the optional msg argument.
Split String	string,separator=None,max_split=-1	Splits the string using separator as a delimiter string. If a separator is not given, any whitespace string is a separator. In that case also possible consecutive whitespace as well as leading and trailing whitespace is ignored. Split words are returned as a list. If the optional max_split is given, at most max_split splits are done, and the returned list will have maximum max_split + 1 elements. Examples: @{words} = Split String ${string}       @{words} = Split String ${string} ,${SPACE}     ${pre} ${post} = Split String ${string} :: 1 See Split String From Right if you want to start splitting from right, and Fetch From Left and Fetch From Right if you only want to get first/last part of the string.
Split String From Right	string,separator=None,max_split=-1	Splits the string using separator starting from right. Same as Split String, but splitting is started from right. This has an effect only when max_split is given. Examples: ${first} ${rest} = Split String ${string} - 1 ${rest} ${last} = Split String From Right ${string} - 1
Split String To Characters	string	Splits the given string to characters. Example: @{characters} = Split String To Characters ${string}
Split To Lines	string, start=0,end=None	Splits the given string to lines. It is possible to get only a selection of lines from start to end so that start index is inclusive and end is exclusive. Line numbering starts from 0, and it is possible to use negative indices to refer to lines from the end. Lines are returned without the newlines. The number of returned lines is automatically logged. Examples: @{lines} = Split To Lines ${manylines}     @ {忽略第一} = 拆分为线 $ {} manylines 1   @ {ignore last} = 拆分为线 $ {} manylines   -1 @ {5th to 10th} = 拆分为线 $ {} manylines 4 10 @ {前两个} = 拆分为线 $ {} manylines   1 @ {last two} = 拆分为线 $ {} manylines -2   如果您只需要获得一行，请使用获取行。
带状线	string， mode = both， characters = None	从给定字符串中删除前导和/或尾随空格。 mode要么left删除前导字符，right要删除尾随字符，both（默认）删除字符串两边的字符或none返回未修改的字符串。 如果characters给出了可选项，则它必须是字符串，并且字符串中的字符将在字符串中被删除。请注意，这不是要删除的子字符串，而是字符列表，请参阅下面的示例。 例子： $ {剥离} = 带状线 $ {空白}你好$ {空白}   应该是平等的 $ {}剥离 你好   $ {剥离} = 带状线 $ {空白}你好$ {空白} 模式=左 应该是平等的 $ {}剥离 尊敬的$ {空白}   $ {剥离} = 带状线 aabaHelloeee 字符数=阿部 应该是平等的 $ {}剥离 你好   Robot Framework 3.0中的新功能。
