做个小偷程序,怎么用正则表达式提取内容?

[windflow]

结构类似如下:
<div class="txtAlgCen fLeft handle" onClick="detail();" title="点击查看详细信息">
<div class="wetDico w02"></div>
<div class="wetSts">阴转多云</div>
<div class="wetTmp"><b>今天</b>：22℃～31℃</div>
</div>
<div class="txtAlgCen fRig handle" onClick="tomorrow();" title="点击查看详细信息">
<div class="wetDico w03"></div>
<div class="wetSts">阵雨</div>
<div class="wetTmp"><b>明天</b>：24℃～31℃</div>
</div>
现在要提取今天和明天的三个<div>里面的内容,肯定要用到分组捕获.试了几次不成功,求教高人!

var str='div class="txtAlgCen fLeft handle" onClick="detail();" title="点击查看详细信息"><div class="wetDico w02"></div><div class="wetSts">阴转多云</div><div class="wetTmp"><b>今天</b>：22℃～31℃</div></div><div class="txtAlgCen fRig handle" onClick="tomorrow();" title="点击查看详细信息"><div class="wetDico w03"></div><div class="wetSts">阵雨</div><div class="wetTmp"><b>明天</b>：24℃～31℃</div></div>'

var b=str.match(/<div class=\"wetTmp\"\>(.*?)<\/div>/)

for(var i=0;i<b.length;i++){

alert(b[i].replace(/<\/?[^>]*>/g,""))
}

多谢,我试试

[超级大笨狼]

private void button2_Click(object sender, EventArgs e)
{
CN.Open();
string Location="";

using (System.Data.DataTable dt = SqlHelper.ExecuteDataset(CN, CommandType.Text, @"select top 1 * from crawled where tag=0 and HtmlInfo like '%class=""BL TMuchBigger_2 Bold""%'").Tables[0])
{

if (dt.Rows.Count > 0)
{
Location = dt.Rows[0]["HtmlInfo"].ToString();
Regex re = new Regex(@"<a href=(.*) class=""BL TMuchBigger_2 Bold"" >");
Regex re2 = new Regex(@"[\d]{2,8}");
if (re.IsMatch(Location))
{
MatchCollection mc;
mc = re.Matches(Location) ;


for (int i = 0; i < mc.Count; i++)
{
Location=mc[i].Value;
string L1 = Location;
Location = re2.Match(Location).Value;
MessageBox.Show(L1 + "\n" +Location);

}

}
else
{
MessageBox.Show("无！");
}

}

}
if (CN.State == ConnectionState.Open)
{
CN.Close();
}
}

已经搞定.
