Question

Please help me to replace all the additional Facebook information from here using C# .net Regex Replace method.

Example

<a href="/l.php?u=http%3A%2F%2Fon.fb.me%2FOE6gnB&amp;h=yAQFjL0pt&amp;s=1" target="_blank" rel="nofollow nofollow" onmouseover="LinkshimAsyncLink.swap(this, &quot;http:\/\/on.fb.me\/OE6gnB&quot;);" onclick="LinkshimAsyncLink.swap(this, &quot;\/l.php?u=http\u00253A\u00252F\u00252Fon.fb.me\u00252FOE6gnB&amp;h=yAQFjL0pt&amp;s=1&quot;);">http://on.fb.me/OE6gnB</a>somehtml

Output

somehtml <a href="http://on.fb.me/OE6gnB">on.fb.me/OE6gnB</a> somehtml

I tried following regex but they didn’t work for me

searchPattern = "<a([.]*)?/l.php([.]*)?(\">)?([.]*)?(</a>)?";
replacePattern = "<a href=\"$3\" target=\"_blank\">$3</a>";

Thanks

I manage to do this using regex with following code

 searchPattern = "<a(.*?)href=\"/l.php...(.*?)&amp;?(.*?)>(.*?)</a>";
          string html1 = Regex.Replace(html, searchPattern, delegate(Match oMatch)
    {
        return string.Format("<a href=\"{0}\" target=\"_blank\">{1}</a>", HttpUtility.UrlDecode(oMatch.Groups[2].Value), oMatch.Groups[4].Value);

    });
