Java正则表达式获取网址和链接文字解析

很久不写正则表达式了，网上看到个面试题关于提取<a href=‘提取我’/>， 各种乱七八糟的解法。

正确的，应该是这样吧：

import java.util.regex.Matcher;
import java.util.regex.Pattern;


public class TestReg {
	
	static void ParseHref(String str) {
		
		System.out.println(str);
		System.out.println("开始匹配");
		
		Pattern pattern = Pattern.compile("(<a([^>]*)href=[\"|\']([^\"\']*)[\"|\']([^>]*)>)", Pattern.CASE_INSENSITIVE);
		Matcher matcher = pattern.matcher(str);
		

		while(matcher.find()) {
			System.out.println("group:" + matcher.group());;
			for(int i = 0 ; i <= matcher.groupCount() ; i++){
				System.out.println(""+ i + ": " + matcher.group(i));
			}
		}
	}
	
	public static void main(String[] args) {
		String str = "<a href=\"www.google.com/sadfs/\" name=\"myname\" />123123 href=\"error.google.com/sadfs/\"55555";

		ParseHref(str);
		
		String s="</p><p style=height:14px><a href=\"http://jingjia.baidu.com\">企业推广</a> | <a href=\"http://top.baidu.com\">搜索风云榜</a> | <a href=\"/home.html\">关于百度</a> | <a href=\'http://ir.baidu.com\'>About Baidu</a></p><p id=b>©2008 Baidu <a href=\'http://www.baidu.com/duty\'>使用百度前必读</a> <a href=\'http://www.miibeian.gov.cn\' target=_blank>京ICP证030173号</a> <a href=\'http://www.hd315.gov.cn/beian/view.asp?bianhao=010202001092500412\'><img src=http://gimg.baidu.com/img/gs.gif></a></p></center></body></html><!--543ff95f18f36b11-->";
		
		ParseHref(s);
	}
}
