如何截取HTML源文件指定部分的内容？

[wode421898419]

我想截取http://mh.163k.com/house/源文件中如下内容，整个页面只有一个class="hotLP"的div，怎么截取好，如果用正则，该怎么写（我正则不大会用）?

<div class="hotLP">
<div class="hd"></div>
<div class="bd">

LZ使用Jquery啊，如果确保整个页面只有一个class="hotLP"的div可以用Jquery写，
So Easy!
//获取hotLP的InnerHTML
$("div .hotLP").html()

[托大人]

string html = "你的Html代码";

Match m = Regex.Match(html, @"(?<code><div[^>]*?class=""hotLP""[^>]*?>[^\b]*?(((?'Open'<div[^>]*?>)[^\b]*?)+((?'-Open'</div>)[^\b]*?)+)*(?(Open)(?!))</div>)", RegexOptions.IgnoreCase);

MessageBox.Show(m.Groups["code"].Value);

首先你要确认你的html代码没有错误，才有可能匹配成功
