How to get each tablerow in regex from a string (C#)?

Basically, I've got a string like this:

<table><tr class="even"><td></td><td></td></tr><tr class="odd"><td></td><td></td></tr></table>

I want to get each tablerow using Regex.Matches (c#)

What would my regex pattern be?

I've tried the following but I think it's probably pretty wrong:

"<tr"(.*)"</tr>" 
[<][t][r](.*)[<][/][t][r][>]"

But even

[t][r].*[t][r]

Gives 0 matches.

Any idea?

Thanks a lot!

Consider the following Regex...

(?<=\<tr.*?\>).*?(?=\</tr\>)

 var str = "<table><tr class=\"even\"><td></td><td></td></tr><tr class=\"odd\"><td></td><td></td></tr></table>";
 string[] trs = Regex.Matches(str, @"<tr[^>]*>(?<content>.*)</tr>", RegexOptions.Multiline)
             .Cast<Match>()
             .Select(t => t.Groups["content"].Value)
             .ToArray();

the "trs" array is your result, containing <td></td><td></td> two times.

edit: This regex is not resilient to missing a </tr> (wich would display fine in any browser). This could be solved using a negative lookahead

Try this:

var s = @"<table><tr class=""even""><td></td><td></td></tr><tr class=""odd""><td></td><td></td></tr></table>";
Regex.Matches(s, @"(<tr .*?</tr>)", RegexOptions.Singleline)

\<tr[\s\S]*?\/tr\>

.?* : All Characters, stop at first match.

\s\S : All Characters, even new lines.

I use RAD Software Regular Expression Designer to create and test REGEX expressions. It is a great tool!
