Great example.. haha.. I knew someone would pull some nice regex out for this one.. I suck at regex. hah
I still like my XML parsing fix, but Leonard's regex is probably better. hah

HI,
> Hello
> I'm trying to extract some text between two tags:
I am answering your question from the perspective that you are going
to have more than one column that you want the data from.
I would use this pattern and this code to test the pattern.
<?
$pattern="/(<td align=\"(.*)\" class=\"(.*)\">(.*)<\/td>)/";
$text='<td></td>
<td align="right" class="yfnc_tabledata3"></td>
<td></td>
<td align="right" class="yfnc_tabledata2"></td>
<td></td>
<td align="right" class="yfnc_tabledata1">1234</td>
<td></td> <td></td> <td></td> <td align="right" class="yfnc_tabledata5"></td> ';
preg_match_all($pattern, $text, $matches);
print_r($matches);
?>
This will give you:
[0] => Array
(
[0] => <td align="right" class="yfnc_tabledata3"></td>
[1] => <td align="right" class="yfnc_tabledata2"></td>
[2] => <td align="right" class="yfnc_tabledata1">1234</td>
)
[1] => Array
(
[0] => <td align="right" class="yfnc_tabledata3"></td>
[1] => <td align="right" class="yfnc_tabledata2"></td>
[2] => <td align="right" class="yfnc_tabledata1">1234</td>
)
[2] => Array
(
[0] => right
[1] => right
[2] => right
)
[3] => Array
(
[0] => yfnc_tabledata3
[1] => yfnc_tabledata2
[2] => yfnc_tabledata1
)
[4] => Array
(
[0] =>
[1] =>
[2] => 1234
)
THen you can loop through $matches[4] and you will get all of the
values in your row. $mathces[3] will give you your class names and
$matches[2] will give you the alignment and $matches[1] will give you
the whole <td blah blah blah /td> string.
You could explode on <tr> and get each new row of your table in a new
element in an array and repeat the process for your entire table.
Do note that my regular expression will only return columns with a
class name and align attribute.
You can use $matches[0] elements if you are needing to replace what is
there with other information.
I hope this helps. Please let me know if it does what you are asking
for as I am in need of good regular expression practice.
If you are needing to alter my regex some you can use
