preg_match_all for html tags

[sonal4php]

i want to retrieve certain elements bound in same format in an html file.

i have lot much raw data in this html file,

i have stored this in string =$data

 

and i am looking for such pattern:

<td width='15%' valign=top>41    </td>

among which 41 is desired result.

 

note: 15% is not constant it can be 15%,25% and 35%

 

i have many rows like this in html file, and i want to pick the same value which is bound in

<td width='15%' valign=top>

and

</td>

i am trying this code:

 

preg_match_all("|<[td width='[0-9]{1}5%' valign=top>]+>(.*)</[/td>]+>|U",$data,$out,PREG_PATTERN_ORDER);
print_r($out[1]);

but i am not getting desired result

can someone please help....

 

thanx

[...] is a character class which does not match a sequence of characters, but individual characters.

 

<pre>
<?php
$string = "<td width='15%' valign=top>41    </td>";
preg_match_all("/<td width='\d+%' valign=top>(\d+)/", $string, $out);
print_r($out[1][0]);
?>
</pre>
