获取html中的<A>标签怎么写正则

public static void main(String[] args) {String s1 = "zwerwr423111111";Pattern p = Patterncompile("([^]+)");Matcher m = pmatcher(s1);while(mfind()){Systemoutprintln(mgroup(3));}} //改了下正则,这样很强大了

<script language="javascript">
//更改路径
function changeImg (obj) {
if(objid == "btn1") {
documentgetElementById('imgshow')src="#1";
}
if(objid == "btn2") {
documentgetElementById('imgshow')src="#2";
}
}
</script>
//两个按钮增加onclick点击事件
<a href="#1" id="btn1" onclick="changeImg(this);">第一个按钮</a>
<a href="#2" id="btn2" onclick="changeImg(this);">第二个按钮</a>
//给设置个id
<img src="#1" id="imgshow" name="imgshow">

$(document)ready(function () {
$("a")each(function () {
if ($trim($(this)val()) == "样式1") {
$(this)attr("href", "链接1");
}
else if ($trim($(this)val()) == "样式2") {
$(this)attr("href", "链接2");
}
});
});

刚写了下，希望对楼主有帮助啊~~
html:

<ul>
<li><a href="cpphpac=common&op=changetpl&name=1"><span id="aa"></span></a></li>
<li><a href="cpphpac=common&op=changetpl&name=2"><span id="bb"></span></a></li>
<li><a href="cpphpac=common&op=changetpl&name=3"><span id="cc"></span></a></li>
</ul>
js:
var Ahref = "cpphpac=common&op=changetpl&name=1";//输入你要判断的那个href
var Index = Ahref[Ahreflength - 1];//得到最后一个字符1,2或3
var ids;//定义要选中的id
switch(Index){
case "1":
ids = documentgetElementById("aa");
break;
case "2":
ids = documentgetElementById("bb");
break;
case "3":
ids = documentgetElementById("cc");
break;
default:
ids = false;
alert("Not Found");
break;
}
if(ids != false){
var ele = documentcreateElement("i");
eleinnerHTML = "haha";
idsappendChild(ele);
}
经测试，没有问题，O(∩_∩)O~
