有关reg表达式的帮助？ [英] Help with reg expressions?

问题描述

需要正常表达方面的帮助，不能自己解决问题。

我有一个网站，例如http://www.website.com我用这段代码来阅读网站的内容。

Hi, need help for a regular expression, cant really figure ir out myself.
I have a website, for example http://www.website.com and I use this code to read the content of the website.

StreamReader webSource = new StreamReader(webResponse.GetResponseStream());

                   string source = webSource.ReadToEnd();

所以我需要一个正则表达式匹配来查找服务器内的所有包含网站URL。所以我需要找到所有这些链接：



http://www.website.com/search/84f2fbfcf85129866221a71b7d48f2da/?cat=124\");

http://www.website.com/search/7569ac370abc2aa02cd3e0760c418cc9/?sCat=38）;

http://www.website.com/show/?i= 2368173& popup = 1mp; search = bcc6928a29fe348a30cbfc2dc1aba4ab& place = 1）;



我不想找到像
这样的链接
http： //www.OTHERwebsite.com/search/84f2fbfcf85129866221a71b7d48f2da/?sCat=124&

任何人都可以帮忙吗？

Can anyone help with this?

推荐答案

这将找到你指定的内容：

（['']）（http://www.website.com/.*？）\ 1

更确切地说，它将在匹配单引号或双引号之间进行搜索。第2组将包含网址。

This will find what you have specified:
(["''])(http://www.website.com/.*?)\1
More exactly it will search for it between matching single or double quotes. Group 2 will contain the url.

我得到语法错误某种方式

I get a syntax error somehow

foreach (Match n in Regex.Matches(source, @(["'])(http://www.website.com/.*?)\1"))
                    {
