求一个正则表达式

[yuankunliuying]

页面源码中存在
<a href="/market/detail/006001/2010-09-27/3443.html" >

要找出类似的href把关于 /market/detail/的链接都找出来。

[路人乙e]

string str = "<a href='/market/detail/23974/aaa.html'></a>lkj<a href='/market/detail/23974/bbb.html'></a>";
Regex.Replace(str, @"(?i)href=(['""]{0,1})(/market/detail/[^\1]+?)\1",
new MatchEvaluator(delegate(Match m){
Console.WriteLine(m.Groups[2].Value);return "";
}));

MatchCollection mc = Regex.Matches(html字符串,@"<a href="/market/detail/[^>]*>");
foreach(Match m in mc)
{
    //m.Value就是你要的每一个类似的标记
}

[wuyq11]

Regex reg = new Regex(@"(?i)<a[^>]*?href=(['""]?)(?<url>[^'""\s>]+)\1[^>]*>");
MatchCollection mc = reg.Matches("");
foreach (Match m in mc)
{
richTextBox2.Text += m.Groups["url"].Value + "\n";
}

少转义了。

MatchCollection mc = Regex.Matches(html字符串,@"<a href=""/market/detail/[^>]*>");
foreach(Match m in mc)
{
    //m.Value就是你要的每一个类似的标记
}

try...

            Regex reg = new Regex(@"(?i)<a[^>]*?href=(['""]?)(?<url>/market/detail/[^'""\s>]+)\1[^>]*>");
            MatchCollection mc = reg.Matches(yourStr);
            foreach (Match m in mc)
            {
                richTextBox2.Text += m.Groups["url"].Value + "\n";
            }
