[PHP] Real world regex

[Craig Westerman]

I'm trying to understand how to write a regex when the only pattern is table
tags.

For one I need to figure out how to match the opening table tag of the 4th
html table on a page.


For another I need to get the 3rd opening table row tr tag after the 7th
opening table tag.


Thanks

 For another I need to get the 3rd opening table row tr tag after the 7th
 opening table tag.

not tested:
(table[^]+.*){6}(table[^]+)([ ]*)(tr[^]*)(.*){2}(tr[^]*)(.*)

Bas,

Thanks for the reply. I can easily grab this test page
http://www.gold-forum.com/table.html using this script. (shown below)
http://www.gold-forum.com/grab2.php

When I try replacing $GrabStart = body; with your $GrabStart =
(table[^]+.*){6}(table[^]+)([ ]*)(tr[^]*)(.*){2}(tr[^]*)(.*);
I get errors.

If you have time, can you show me what I need for:

$GrabStart = ???; //3rd opening table row tr tag after the 7th opening
table tag
$GrabEnd = ???; //3rd closing table row tr tag after the 7th closing
table tag

Thanks
