regular expressions might not be the best tool for your purpose, see
Parsing HTML in Microsoft C#
http://www.developer.com/net/csharp/article.php/2230091
or use SgmlReader then process the xml with classes in System.Xml

但愿下面这一段HTML代码能给你灵感：
<html>
<head>
<title></title>
<meta name="GENERATOR" content="Microsoft Visual Studio .NET 7.1">
<meta name="vs_targetSchema" content="http://schemas.microsoft.com/intellisense/ie5">
<script id="clientEventHandlersJS" language="javascript">
<!--
function Button1_onclick()
{
var text1 = document.getElementById('Textarea1');
if(text1 == null)
return;
for(i = 0;i < document.all.length; i++)
{
text1.value += document.all(i).tagName + '\r\n';
for(var j = 0; j < document.all(i).attributes.length; j++)
{
if(document.all(i).attributes[j].specified)
{
text1.value += ' ├→ ' + document.all(i).attributes[j].nodeName + '=' + document.all(i).attributes[j].nodeValue + '\r\n';
}
}
}
}
//-->
</script>
</head>
<body>
<TEXTAREA id="Textarea1" style="WIDTH: 736px; HEIGHT: 392px" name="Textarea1" rows="24" cols="89">
</TEXTAREA><br><br /><INPUT id="Button1" type="button" value="Button" name="Button1" language="javascript" onclick="return Button1_onclick()">
</body>
</html>
