谁给个正则表达式
可以得到只剩下冒号以后的东西：
如
html 
head 
title

------解决方案--------------------
顶，正则表达式的语法繁琐，不过用js就容易多了啊！
------解决方案--------------------

Java code

import java.util.regex.*;
public class Test {
    public static void main(String[] args) {
        String str = "Tag (0[0,0],6[0,6]): html\nTag (6[0,6],12[0,12]): head\nTag (12[0,12],19[0,19]): title\nTxt (19[0,19],23[0,23]): 这是标题\nEnd (23[0,23],31[0,31]): /title";
        
        System.out.println("---------------");
        System.out.println(str);
        System.out.println("---------------");
        System.out.println();
        
        Pattern pattern = Pattern.compile("[^:]*:([^:]*)$", Pattern.MULTILINE);
        Matcher matcher = pattern.matcher(str);
        while(matcher.find()) {
            System.out.println(matcher.group(1));
        }
    }
}
