问题 I have a string that contains some text followed by a blank line. What's the best way to keep the part with text, but remove the whitespace newline from the end? 回答1: Use String.trim() method to get rid of whitespaces (spaces, new lines etc.) from the beginning and end of the string. String trimmedString = myString.trim(); 回答2: String.replaceAll("[\n\r]", ""); 回答3: tl;dr String cleanString = dirtyString.strip() ; // Call new `String::string` method. String::strip… The old String::trim method

问题 what i'm trying to do here is to delete the longest line from a txt file. Code does it's job, but i also need it to delete multiple "longest lines" and blank lines as well. Any ideas on how to do it? Code is in C# namespace _5_2 { //------------------------------------------------------------ class Program { const string CFd = "..\\..\\U1.txt"; const string CFr = "..\\..\\Results.txt"; static void Main(string[] args) { int nr; Read(CFd, out nr); Print(CFd, CFr, nr); Console.WriteLine("Longest

问题 In excel, I have a text string, which contains numbers and text, that I strip the numbers out of with a formula. However, sometimes it is possible that the text string will be blank to begin with so if this happens I use "" to return a blank instead of a 0. When I link this excel sheet to an access database it will not let me format this column as currency because it is picking up the "" as text along with the stripped out numbers as numbers. Any solutions on how to fix this? Is there another

blank.lines.skip = TRUE fails with read.fwf?

问题 There are four blank lines at the end of my file. > data=read.fwf("test2",head=F,widths=c(3,1,-3,4,-1,4),blank.lines.skip = TRUE) > data When I run this code, the blank.lines.skip argument is ignored. I still get blank lines in my output. The file is: x1 F 1890 1962 x2 1857 1936 x3 1900 1978 x4 1902 1994 x5 F 1878 1939 and four blank lines at the end. 回答1: It looks like you're right that blank.lines.skip does not apply to read.fwf -- would have to dig in the code to figure out why, but read

Checking for blank lines before PHP opening or closing tag

问题 I have an error in my WordPress website (XML parsing error) because there is a blank line before the <DOCTYPE> . Probably this is caused by a blank line in one of the theme or plugin files before the PHP opening tag <?php or after the closing tag ?> . I already checked some files (theme index.php , header.php , functions.php and a few plugins) but did not found the cause. Is there a smart trick to check all files for any blank lines before or after the php tags? Some Regex maybe? Or otherwise

How can my XSLT filter avoid leaving blank lines in output XML when deleting elements, without changing indentation otherwise?

由 和自甴很熟 提交于 2019-12-10 10:39:22
问题 I am writing an XSLT filter which reads an XML file, and generates a shorter XML file with some selected elements (and all their children) removed. So far, my filter gives me output which is valid, well-formed XML, but it has blank lines where the removed elements used to be. Formally, I think the text node before the removed element remains, causing the blank line. I would like to remove this blank line, but leave all other indentation as-is. How can I do this?
