Answer 1

string s = "..";   
Regex re = new Regex(@"<a[^>]*href=(""(?<href>[^""]*)""|'(?<href>[^']*)'|(?<href>[^\s>]*))[^>]*>(?<text>.*?)</a>", RegexOptions.IgnoreCase | RegexOptions.Singleline);   
Match m  = re.Match(s);   
if(m.Success)   
{   
  string link = m.Groups["href"].Value;   
  string text = Regex.Replace(m.Groups["text"].Value,"<[^>]*>","");   
  Console.WriteLine("link:{0}\ntext:{1}", link, text);   
}a标签的文字和地址

Answer 2

恩，感谢楼上大哥的回复~~
我测试了一下,
LEVIS 夏款个性印花短袖T恤  M号咖啡色 
http://item.taobao.com/auction/item_detail-0db1-c010d1d1e4bd4480741f6e84e41e6abe.htm 
这两个数据我获取到了
麻烦再把另外几个数据提取一下啊，谢谢~~~
马上结贴~~~

Answer 3

<img[^>]*src=(""(?<src>[^""]*)""|'(?<src>[^']*)'|(?<src>[^\s>]*))[^>]*>图片的

Answer 4

<span>.*?</span>一口价的

Answer 5

<strong>(.*?)</strong>价格的

Answer 6

<img[^>]*src=(""(?<src>[^""]*)""|'(?<src>[^']*)'|(?<src>[^\s>]*))[^>]*>

Answer 7

<div class=""remain-date"">(.*?)</div>剩余天数的

Answer 8

恩，但是这个也有问题了~~~
string s = "..";   
Regex re = new Regex(@"<a[^>]*href=(""(?<href>[^""]*)""|'(?<href>[^']*)'|(?<href>[^\s>]*))[^>]*>(?<text>.*?)</a>", RegexOptions.IgnoreCase | RegexOptions.Singleline);   
Match m  = re.Match(s);   
while(m.Success)   
{   
  string link = m.Groups["href"].Value;   
  string text = Regex.Replace(m.Groups["text"].Value,"<[^>]*>","");   
  Console.WriteLine("link:{0}\ntext:{1}", link, text);   
  m = m.NextMatch(); 
}
那么解析出来的：
link多了很多，text有时候为空，具体原因是：
h4><a target="_blank" href='http://item.taobao.com/auction/item_detail-0db1-c010d1d1e4bd4480741f6e84e41e6abe.htm'>LEVIS 夏款个性印花短袖T恤  M号咖啡色</a></h4>
                        <div class="item">
                            <div class="pic">
                                <a target="_blank" href='http://item.taobao.com/auction/item_detail-0db1-c010d1d1e4bd4480741f6e84e41e6abe.htm'>
这样首先解析出http://item.taobao.com/auction/item_detail-0db1-c010d1d1e4bd4480741f6e84e41e6abe.htm
LEVIS 夏款个性印花短袖T恤  M号咖啡色
http://item.taobao.com/auction/item_detail-0db1-c010d1d1e4bd4480741f6e84e41e6abe.htm
（空）

Answer 9

这样的正则要是写起来太长了，差不多吧HTML写了一遍

Answer 10

第一个地址：
(?<=<h4>.*?href=').*?(?='>)
(LEVIS 夏款个性印花短袖T恤  M号咖啡色)说明：
(?<=<h4>.*?'>).*?(?=\<)
图片地址：
(?<=<h4>.*?<img src=").*?(?=")
一口价：
(?<=<span>一口价</span><strong>).*?(?=\<)
