获取淘宝商品描述和价格

1)价格

(?<=<strong\\s+[^>]*\"J_StrPrice\"\\s+>)(?<1>[^<]*)(?=</strong>)

2)描述

分为2步，先获取描述地址，后获取地址内容。

(?<=')(?<1>http://dsc.taobaocdn.com.*)(?=')

取得地址后url 后，请求 http://dsc.taobaocdn.com/url
(?<=desc=')(?<1>.*)(?=';)

代码

2 string tbdescUrl = GetMatchString(reg);
3 HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(tbdescUrl);
4
5 HttpWebResponse req = (HttpWebResponse)request.GetResponse();
6 Stream stream = req.GetResponseStream();
7 StreamReader sr = new StreamReader(stream, Encoding.Default);
8 string desc = sr.ReadToEnd();

reg = new Regex("(?<=desc=')(?<1>.*)(?=';)", RegexOptions.Singleline | RegexOptions.Compiled);
return GetMatchString(reg, desc);
