Java字符串处理HTML标签

Don't use regular expressions to parse HTML JTidy any of these

    String s = "<title>test title</title>";
    Pattern p = Pattern.compile("<title>(.*?)</title>");
    Matcher m = p.matcher(s);
    while(m.find()){
        System.out.println(m.group(1));
    }

It is inadvisable to parse XML/HTML with regular expressions.

package org.apache.people.mclark.examples.regex;
import java.util.regex.*;
public class Regex1 {
    public static void main(String[] args) {
        final String subjectString = "<title>test title</title>\n" +
          "blabla bla more text"; 
        Pattern regex = Pattern.compile("<title>(.*?)</title>(.*)",
                Pattern.DOTALL);
        Matcher regexMatcher = regex.matcher(subjectString);
        if (regexMatcher.find()) {
            String pageTitle = regexMatcher.group(1);
            String leftOvers = regexMatcher.group(2);
            System.out.println("pageTitle[" + pageTitle + "]");
            System.out.println("leftOvers[" + leftOvers + "]");
        } else {
            System.out.println("no match");
        }
    }
}
