Question

Image this table:

<table cellpadding="0" border="0">
<tr class="someclass">

<td>blah blah THISISIMPORTANT blah blah</td>

</tr>
</table>

I want to select only the tables that have TDs with the innerHTML that contains ‘THISISIMPORTANT’.

This must be done with regular expressions in c#

this is what i have tried:

<table\s*.*?\s*>\s*.*?\s*<td\s*.*?\s*>\s*.*?\s*</td>\s*.*?\s*</table>

Answer 1

/<table[^>]*>(?:.(?!<\/table>))*<td[^>]*>(?:.(?!<\/td>))*THISISIMPORTANT.*?<\/td>.*?<\/table>/

That’s close… I mean, so long as no one uses a “>” inside a tag, you’re fine. But you really should find a better way to do it than regex.
