问题 I am using the function dlmcell in Matlab to output text. I want text on a new line each time I append using dlmcell. When I open my written document in Notepad++, each snippet of text is on a new line as I want it. However, opening it in Notepad that comes with windows, everything is on the same line.

问题 This is likely a very simple fix but I can't figure it out! I'm trying to match (up to) 3 capitalized words in a row given the following text. Russell Lake West . The match should include all 3 words. This regex will match the first 2 words but not the third (demo here): (([A-Z][a-z]+)\s{0,2}([A-Z][a-z]+)?\s{0,2}([A-Z][a-z]+)?) This regex will match all 3 words, but I had to copy/paste the whitespace between Lake and West for it to work (demo here): (([A-Z][a-z'-]+)\s{0,2}([A-Z][a-z'-]+)? \s

问题 I'm using the SAX xml parser to parse some xml data which contains newlines. When using Attributes#getValue, the newline data is lost. How can keep the newlines? 回答1: you can use this code when getting the String to parse: public void characters(char ch[], int start, int length) { for(int i=start; i<length; i++) if(!Character.isISOControl(ch[i])) content.append(ch[i]); } 回答2: The solution was to use instead of \n 来源： https://stackoverflow.com/questions/3401111/preserve-newlines-when-parsing

问题 I have an assignment to create a lexical analyser and I've got everything working except for one bit. I need to create a string that will accept a new line, and the string is delimited by double quotes. The string accepts any number, letter, some specified punctuation, backslashes and double quotes within the delimiters. I can't seem to figure out how to escape a new line character.

问题 I want to match complete strings to a specific pattern. Let's say : word = "aaaa" test = re.match(r"^aaaa$", word) # this returns True However, if the word is followed by a newline character : word = "aaaa\n" test = re.match(r"^aaaa$", word) # Also returns True :( But I want to find a way for it to return False in this last case.

How would I replace the CR-LF with a <br /> ? 回答1: CF has a function for this called ParagraphFormat(): <cfset form.userText = paragraphFormat(form.usertext)/> From the help docs - Replaces characters in a string: Single newline characters (CR/LF sequences) with spaces Double newline characters with HTML paragraph tags ( <p> ) It may do more than you want in that it
