removing-whitespace

问题 I am working on a program that take user input for two file names. Unfortunately, the program can easily break if the user does not follow the specified format of the input. I want to write code that improves its resiliency against these types of errors. You'll understand when you see my code: # Ask the user for the filename of the qseq file and barcode.txt file print "Please enter the name of the qseq file and the barcode file separated by a comma:"; # user should enter filenames like this:

问题 I want to remove spaces from all attributes in my xmls using xslt. I used strip-space , but that removes the spaces from nodes.

问题 This question already has answers here : Remove spaces from std::string in C++ (14 answers) Closed 4 years ago . In C++, what's an easy way to turn: This std::string \t\tHELLO WORLD\r\nHELLO\t\nWORLD \t Into: HELLOWORLDHELLOWORLD 回答1: Simple combination of std::remove_if and std::string::erase. Not totally safe version s.erase( std::remove_if( s.begin(), s.end(), ::isspace ), s.end() ); For safer version replace ::isspace with std::bind( std::isspace<char>, _1, std::locale::classic() )

问题 I typically use the following code in JavaScript to split a string by whitespace. "The quick brown fox jumps over the lazy dog.".split(/\s+/); // ["The", "quick", "brown", "fox", "jumps", "over", "the", "lazy", "dog."] This of course works even when there are multiple whitespace characters between words. "The quick brown fox jumps over the lazy dog.".split(/\s+/); // ["The", "quick", "brown", "fox", "jumps", "over", "the", "lazy", "dog."] The problem is when I have a string that has leading

问题 I know removing trailing whitespace can be done with a pre-commit hook. I am interested in doing it manually. I read the question here: Make git automatically remove trailing whitespace before committing - Stack Overflow The answer closest to what I want is the "automatic version" from ntc2: (export VISUAL=: && git -c apply.whitespace=fix add -ue .) && git checkout . && git reset That command works well except it seems to be only for changes on files that are already in the repo, not new

问题 I am using Bootstrap's Navbar and Bootsrap's grid to display a Navbar with a image immediately underneath the Navbar. However, for some reason there is whitespace between this Navbar and the image. When I use firebug to investigate the location of the whitespace, it looks like the Navbar is top-aligned within its containing . I have tried to fix this by using CSS to bottom-align the navbar, to no avail. How can I eliminate this whitespace? <!-- Top Navigation Bar --> <div class="row" id=

问题 I am trying to write something that will replace all the spaces in a string with an underscore. What I have so far. string space2underscore(string text) { for(int i = 0; i < text.length(); i++) { if(text[i] == ' ') text[i] = '_'; } return text; } For the most part this would work, if I was doing something like. string word = "hello stackoverflow"; word = space2underscore(word); cout << word; That would output "hello_stackoverflow", which is just what I want. However if I was to do something

问题 hello I've got text file with lines format 1|few ewf ew fewfew I need to parse it but I don't know how can I drop whitespaces tail from second value I don't know. Here is my segmentation fault try so far char* token1; char* token2; char* search = "|"; char* search2 = " "; // double space because string can contains single space while (fgets(line, 150, f)) { token1 = strtok(line, search); token2 = strtok(search, search2); // <- segfault //token2 = strtok(NULL, search); <- contains a lot of

问题 How can I check if a Python string at any point has a single space before new line ? And if it does, I have to remove that single space, but keep the new line symbol. Is this possible? 回答1: def remspace(my_str): if len(my_str) < 2: # returns ' ' unchanged return my_str if my_str[-1] == '\n': if my_str[-2] == ' ': return my_str[:-2] + '\n' if my_str[-1] == ' ': return my_str[:-1] return my_str Results: >>> remspace('a b c') 'a b c' >>> remspace('a b c ') 'a b c' >>> remspace('a b c\n') 'a b c
