Regex with vb.net

Question

Hi,

I have the following html contained in a string.

<tr>
   <td>Hello</td>
</tr>
<tr>
   <td>World</td>
</tr>
<tr>
   <td>lets all smile</td>
</tr>

I would like to use RegEx to find the <tr></tr> that contains the text "World". The difficulty is that there might be other <td> around the one that contains the search text. So we need to be able to search for the <tr> and </tr> nearest to the search text with any text between the <tr> and the search text.

The result of the match would be.

<tr>
   <td>World</td>
</tr>

I'm using vb.net by the way.

Could anyone help at all?

Thanks

Richard

First of all, it should be pointed out that you want to use the HTML Agility Pack, and not regex, for this kind of things.

But other than that, a pattern could look like:

(<tr>.*?World.*?</tr>)

It's a rather lousy pattern, but then again, use the agility pack.
