will be helpful for those in need When using e.g. online regex tools, when the whole regex is enclosed in slashes, the regex required in your case is:
code :
import java.util.*;
import java.lang.*;
import java.util.regex.*;

class Rextester {  
    public static void main(String args[]) {
        String src = "/*\n" +
            "This is my multi-line comment.\n" +
            "This is second line of the comment.\n" +
            "*/\n" +
            "/**\n" +
            "Any method description.\n" +
        Matcher m = Pattern.compile("/\\*(?!\\*).+?\\*/", Pattern.DOTALL).matcher(src);
        int cnt = 0;
        while (m.find()) {
            System.out.println(String.format("Found %d:\n%s", ++cnt, m.group()));
Found 1:
This is my multi-line comment.
This is second line of the comment.

should help you out Well, if you want to use regex, then you can use replaceAll. This solution uses a reluctant quantifier and a backreference:
code :
String cleanxml = rawxml.replaceAll(".*?(<item>.*)", "$1");
String cleanxml = rawxml.replaceFirst(".*?(?=<item>)", "");
String cleanxml = rawxml.substring(rawxml.indexOf("<item>"));

help you fix your problem I am new to regular expressions. I want to use java's replaceAll() function to replace any CSS comments in a string. , One example where a simple regular expression fails is:
code :
body { font-family: "/* this is not a comment */"; }
str.replaceAll("/\\*.*?\\*/", "");

Given (pattern)??, it will first test for empty string, then if the rest of the pattern can't match, it will test for pattern.
code :
Pattern.compile("</??tag(\\s+?.*?)??>", Pattern.CASE_INSENSITIVE)

To fix the issue you can do Three questions in as many hours. Must be a record of some sorts.
