问题描述
我想做个数据采集器，把中国体育彩票开奖的信息取出来。不懂怎么动手，请详细指点一下。
解决方案
解决方案二：
可以用http协议获取中国体育彩票网站的信息，然后根据获取到的html数据进行正则匹配出开奖的信息……
解决方案三：
protectedvoidButton1_Click(objectsender,EventArgse){WebRequestwc=HttpWebRequest.Create("http://www.cznd.gov.cn/node/jrgxq_qnyw/2013-7-5/137512575342148320.html");wc.ContentType="application/x-www-form-urlencoded;charset=gb2312";using(WebResponsewq=wc.GetResponse()){using(Streams=wq.GetResponseStream()){using(StreamReadersr=newStreamReader(s,Encoding.GetEncoding("gb2312"))){stringhtml=sr.ReadToEnd();Matchm=Regex.Match(html,@"(?i)<td[^>]*?class=(['""]?)NewsContent1[^>]*?>s*?<p[^>]*?>s*?([sS]*?)</p>");stringresult=m.Groups[2].Value;Console.Write(result);Console.ReadLine();}}}}
前几天看到的一个案例.

解决方案五：
其实主页面采用了框架iframe,指向地址为因此你得到该地址的内容就可以了示例代码如下WebRequestwc=HttpWebRequest.Create("http://www.lottery.gov.cn/lottery/draws/Global.aspx");wc.ContentType="application/x-www-form-urlencoded;charset=gb2312";using(WebResponsewq=wc.GetResponse()){using(Streams=wq.GetResponseStream()){using(StreamReadersr=newStreamReader(s,Encoding.GetEncoding("utf-8"))){stringhtml=sr.ReadToEnd();stringpattern=@"(?i)<tr((?!.*?bgcolor)[^>]*?)>s*?<td[^>]*?>s*?<font>([^>]*?)</font>s*?</td>s*?<td[^>]*?>([^<>]*?)</td>s*?<td[^>]*?>s*?<table[^>]*?>[sS]*?(<td[^>]*?>((?<Num>d+)|s*?)</td>)*?s*?</tr>s*?[sS]*?</table>";varresult=Regex.Matches(html,pattern).OfType<Match>().Select(a=>new{玩法=a.Groups[2].Value,期号=a.Groups[3].Value,开奖号=string.Join("",a.Groups["Num"].Captures.OfType<Capture>().Select(b=>b.Value))});/*+[0]{玩法="大乐透",期号="13082",开奖号="03092526330312"}<AnonymousType>+[1]{玩法="排列3",期号="13191",开奖号="473"}<AnonymousType>+[2]{玩法="排列5",期号="13191",开奖号="47344"}<AnonymousType>+[3]{玩法="22选5",期号="13172",开奖号="0809141519"}<AnonymousType>+[4]{玩法="7星彩",期号="13082",开奖号="6080148"}<AnonymousType>*/}}
解决方案六：
爬取数据啊主要还是html分析可以使用htmlagilitypack参考http://www.cnblogs.com/wangchuang/archive/2013/03/11/2953638.html
解决方案七：
我已经得到该地址的内容，但是正则啊，我还是搞不定啊
解决方案八：
我没有自己写我现在使用的是ET你可以试试
解决方案九：
你不使用正则那就要学xpath，我建议在html解析的时候就使用xpath就可以了，比其它的解析方法要好的多。
