RegEx Help

Question

0.00/5 (No votes)

Ive been trying to figure out a RegEx for the following:

XML

<td width="50%" height="19">
<a href="sample_weblink.htm">
Sample Weblink</a></td>
<td width="50%" height="19">

But I can't figure out the RegEx to match only the weblink. In other words I only want to match what's between:

<a href="
and
">

Any help would be appreciated.
The regex needs to be Global.

Thanks!

Try non-greedy evaluation, that is, add a ? after the + or *.

E.g.

C#

class Program

{

    static void Main(string[] args)
    {
        string strInput = @"
<td width=""50%"" height=""19"">
<a href=""sample_weblink.htm"">
Sample Weblink</a></td>
<td width=""50%"" height=""19"">
";
        var objMatch = Regex.Match(strInput, @"<a\s+href=[""'](.*?)[""']\s*>");
        if (objMatch.Success)
        {
            Console.WriteLine("Match: {0}", objMatch.Groups[1].Value);
        }
    }
}

Note: the doubling of the quotes is needed to have embedded quotes in a @"..." string.

Cheers

Thanks! I have tested this with http://gskinner.com/RegExr/ and it works. But when I use http://regexpal.com/ it does not work. I am wondering if this will work with C# .NET?
