I see you've tried a saw where a screwdriver is needed.

Have you tried using an HTML parser?

Use the HtmlAgilityPack or a similar parser. If you must use Regex, and you don't care that much about robustness or maintainability, you could try something like:

string pattern = "(?<=id='OrdreID).+(?=<td colspan=\"9\" osv)";
