Experts,

I'm trying to take out the content between the following tags in an RSS document:

<description>Content here </description>

My code is included below which outputs the matches however I get the following at the beginning of each line..

on>

so the line looks like

on> Some RSS content
on> Some more RSS content

So it's obviously not quite right.  Please help

on>
<?php
 
$pattern = '/<description>(.*?)<\/description>/';
 
preg_match_all($pattern, $buffer, $matches);
//print_r($regMatches);
 
foreach ($matches[0] as $val) {
	$val = substr($val, 10);
	echo "$val <br>";
}
 
?>

The subpattern defined by your parentheses isn't in $machtes[0], but in $matches[1]:

<?php
 
$pattern = '/<description>(.*?)<\/description>/';
 
preg_match_all($pattern, $buffer, $matches);
//print_r($regMatches);
 
foreach ($matches[1] as $val) {
        echo "$val <br>";
}
 
?>
