Simple Regex help for C #

Something like the following regex?

MatchCollection matches = Regex.Matches(yourString, @"http://\S+?-(\d+)/") 
foreach(Match m in matches)
{
    string id = m.Captures[0].Value;
    string url = m.Value;
}

      

        
        
        
      

    

which will grab links (starting with http://

), then everything is not space (spaces are guaranteed not in HTTP (URI) links) and assumes it ends with numbers and a trailing slash (this will properly remove &

in your example or other trailing text).

EDIT: The whole match is a reference, the ID is in the first brackets, updated code to show how to get the information.

Update: if numbers + numbers + forward slash can appear in the url more than once in the url, then greed must be used, but subsequent links (no extra text with spaces) will be matched. If dash + numbers + slash occurs only once for each url, then laziness is preferable. This solution is currently in the code above.

An alternative approach

From the updates and additional information, I understand that there is a lot of confusion in the text. Another approach might be simpler: split everything by http://

and view the results. This avoids the need for a complex look-forward / backward regex and ensures that successive links (i.e. no text in between) are handled correctly:

// zero-width split:
string[] linksWithText = Regex.Split(yourString, @"(?<=http:\S+-\d+/)");
foreach (string link in linksWithText)
{
    Match m = Regex.Match(link, @"(.*)(http:\S+-(\d+)/)$");
    if (m.Success)
    {
        string text = m.Groups[1].Value;
        string url = m.Groups[2].Value;
        string id = m.Groups[3].Value;
    }
}

      

        
        
        
      

    

Update: The alternative approach has been updated. Text (name) first, then URL. Note the negative appearance of the expression to split into a zero-width spot by taking anything before the url to the end of the url.
