关于匹配网页中的URL正则表达式，急急急

Question

[0-9a-zA-Z]+://[-_\.a-zA-Z0-9]+[^ \t<>]*
这是我的一段正则表达式
是专门匹配网页中的URL地址的
我发现有点问题，抓取网页中的URL时，哪些地址后面都带啦个单引号（”）
下面是我从网页中抓取的URL地址：
http://www.sina.com.cn/contactus.html"
http://www.lenovo.com.cn/Public/public_bottom/contact.shtml"
http://www.tom.com/about/about_contact_1.htm"
怎么才能把后面得单引号不要呢深入一层：
就是我要把在Google中搜索到的记录，只抓取标题中的10条记录
就是每页只显示的10条记录的那10个URL地址
下面还有很多分页，都要抓取出来，我现在怎么把那个页面多余的URL全部过滤掉呢？
还有怎么把其他分页的URL也抓取出来，但是只抓取每个页面的那主要的10条URL地址
其他的全部过滤掉
各位大虾给个详细的讲解，最好有代码，正则表达式等等

Answer 1

http://([\w-]+\.)+[\w-]+(/[\w- ./?%&=]*)?

Answer 2

或者 "(http://([\w-]+\.)+[\w-]+(/[\w- ./?%&=]*)?)" ，Group[1]就是你要的。

这些是我抓到的元数据

Answer 4

//首先你得结果中不是单引号是双引号，这两个总不至于分不清吧
"[0-9a-zA-Z]+://[-_\.a-zA-Z0-9]+[^ \t<>]*" 
//  因为你的最后的[^ \t<>] 包含单引号双引号 所以取值的时候就包括了要想不要那就加进去
// LZ是不是在源码中取阿，用这个
@"(?<=<a\s+.*?href\s*=\s*[""']?)[^'""\s]+"

这些是我抓到的元数据

Answer 7

把你那个正则改为
[0-9a-zA-Z]+://[-_\.a-zA-Z0-9]+[^ \t <>"]*
就行了

Answer 8

我是先获取页面的源码，然后取源码中的URL
我刚试啦一下，好像不行饿

Answer 9

改成这样
[0-9a-zA-Z]+://[-_\.a-zA-Z0-9]+[^ \t <>"]*

Answer 10

这样是ok啦
我现在要过滤其他的一些URL链接应该要怎么做呢？
或者更好的正则表达式怎么写呢
就是在Google上搜索记录，比如我要搜‘联系我们“然后只抓取那10条主标题的URL
其次还要根据分页把其他页面的URL也要抓取出来，每页都取那主要的10条主标题URL

Answer 11

Regex UrlRegex = new Regex(@"([0-9a-zA-Z]+://[-_\.a-zA-Z0-9]+[^ \t <>"]*)", RegexOptions.IgnoreCase | RegexOptions.Compiled);
有错啊

Answer 12

Regex UrlRegex = new Regex(@"([0-9a-zA-Z]+://[-_\.a-zA-Z0-9]+[^ \t <>""]*)", RegexOptions.IgnoreCase | RegexOptions.Compiled);"要转义，写成二个就行了

Answer 13

你那个可以的

Answer 16

<a\shref\s*="(?<URL>[^"]*).*?>(?<title>[^<]*)</a>
用这个正则表达示
string content="网页内容";
 Regex r = new Regex(@"<a\shref\s*=""(?<URL>[^""]*).*?>(?<title>[^<]*)</a>", RegexOptions.IgnoreCase|RegexOptions.Singleline);
 MatchCollection ms = r.Matches(content);
  foreach (Match m in ms)
            { 
    if(m.Success)
                {
                  string title=m.Groups["title"].Value;
                  string url = m.Groups["URL"].Value;
                if(title=="联系我们")
                {
                 //把url加入列表
               }
}
}

Answer 17

搜索到的记录有的是
华友世纪－联系我们
TOM在线-联系方式
像这种的话那就抓不了啊
还有很多关于该记录的是分页显示的,那怎么把其他分页里面的主标题URL也得到呢

Answer 19

@"(?<=<a\s+.*?href\s*=\s*[""']?)[^'""\s]+(?![^>]+>\s*(网页快照|类似结果))"
// 这个 

Answer 20

@"(?<=<h3[^>]*>\s*<a\s+[^<>]*href\s*=\s*[""']?)[^'""\s]+"
// 这个也行

Answer 22

不明白？　什么抓不了，什么分页？　　什么什么最好的正则？--其次还要根据分页把其他页面的URL也要抓取出来，每页都取那主要的10条主标题URL　这不是正则干的事吧

Answer 23

这是我的代码：
 Regex UrlRegex = new Regex(@"(<a\shref\s*=""(? <URL>[^""]*).*?>(? <title>[^ <]*) </a>)", RegexOptions.IgnoreCase | RegexOptions.Singleline); 
            MatchCollection matches = UrlRegex.Matches(ContentHtml);
            foreach (Match match in matches)
            {
                if (match.Success)
                {
                    string title = match.Groups["title"].Value;
                    string htmlurl = match.Groups["URL"].Value;
                    if (title == "联系我们")
                    {
                        this.listurl.Items.Add(htmlurl);
                        strwriterobj.WriteLine(htmlurl);
                    }
                }
             //this.listurl.Items.Add(match.Value.ToString());
             //strwriterobj.WriteLine(match.Value.ToString());
            }
            MessageBox.Show("抓取完毕！！！");
            strwriterobj.Close();
            sr.Close();
            stream.Close();
            rs.Close();
然后我运行就报错啦：System.ArgumentException: 正在分析“(<a\shref\s*="(? <URL>[^"]*).*?>(? <title>[^ <]*) </a>)”－ 无法识别的分组构造。
那个分页是不用正则的，我想问下那个怎么解决啊

Answer 24

Regex UrlRegex = new Regex(@"(<a\shref\s*=""(?<URL>[^""]*).*?>(?<title>[^ <]*)</a>)", 
可能是?号之间有空格

Answer 25

正则式没问题啦
可是抓不了东西啊
Regex UrlRegex = new Regex(@"(<a\shref\s*=""(?<URL>[^""]*).*?>(?<title>[^ <]*)</a>)", RegexOptions.IgnoreCase | RegexOptions.Singleline); 
            MatchCollection matches = UrlRegex.Matches(ContentHtml);
            foreach (Match match in matches)
            {
                if (match.Success)
                {
                    string title = match.Groups["title"].Value;
                    string htmlurl = match.Groups["URL"].Value;
                    if (title == "联系我们")
                    {
                        this.listurl.Items.Add(htmlurl);
                        strwriterobj.WriteLine(htmlurl);
                    }
                }
             //this.listurl.Items.Add(match.Value.ToString());
             //strwriterobj.WriteLine(match.Value.ToString());
            }
代码没有问题啊
