regex

问题 I'd like to grab a string between tags. My tags will be with curly braces. {myTag}Here is the string{/myTag} So far I have found #<\s*?$tagname\b[^>]*>(.*?)</$tagname\b[^>]*>#s This one matches tags with angle brackets <> . I couldn't figure out how to make it look for curly braces. Eventually I would like to parse whole page and grab all matches and build an array with strings. This is the code: function everything_in_tags($string, $tagname) { $pattern = "#<\s*?$tagname\b[^>]*>(.*?)</

问题 How do I delete automatically the brackets and the numbers? Example: [132] [100] [1011] How can I delete with Notepad++? 回答1: Open up the Replace dialog, then enter \[\d+\] in the "Find what" box, and make sure regular expressions are used as search mode. By clicking Replace All , Notepad++ will remove all instances of square brackets with one or more digits in between. 来源： https://stackoverflow.com/questions/26819534/delete-brackets-and-numbers-via-notepad

问题 I am doing a parser for nand2tetris project. I want to check if the destination field is either M|D|MD|A|AM|AD|AMD and their different ways of combinations like MA not only AM . ^(M|D|MD|A|AM|AD|AMD)\s*=$ This regex correctly matches AM= , but not MA= . I don't want to list out all the possible combinations of those tokens, is there a way to do it simply? 回答1: This should do it: ^(?=[MDA]+$)(?!.?(.).?\1).{1,3}$ Demo The negative lookahead attempts to match two "M" 's, two "D" 's or two "A" 's

问题 Based off Regex Until But Not Including, I'm trying to match all characters up until a word boundary. For example - matching apple in the following string: apple < I'm doing that using: a negated set [^] with a word boundary \b and a plus + repeater Like this: /a[^\b]+/ Which should look for an "a" and then grab one or more matches for any character that is not a word boundary. So I would expect it to stop before < which is at the end of the word Demo in Regexr Demo in StackSnippets var input
