Re: Text between two tags

[Leonard Burton <leonardburton@xxxxxxxxx>]

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
