xml nodes with same name

[etoast]

Hello
Found a script on these boards which almost works.
Problem is <description> node in the xml exists twice.

It outputs the first one, but I want the second.
How do I change this script so it outputs channel->item->description
rather than channel->description ?

<?php
## GET WEATHER INFO TO STRING
$weather = file_get_contents("http://feeds.bbc.co.uk/weather/feeds/rss/5day/id/3616.xml");

## SET UP PATTERNS
$description = "@<description>([a-zA-Z0-9\,\-\_\s]*)</description>@";

## MATCH PATTERNS, GET INFORMATION
preg_match($description, $weather, $matches);
$info['desc'] = $matches[1];

## DISPLAY INFORMATION
echo 'Temp: '.$info['desc'].'';
?> 

Many thanks!

You could use preg_match_all(), then do a print_r($matches[1]) to see which sub-index has the desired value (probably something like $matches[1][1]).

why not keep it in it's native XML format.

<?php 
$xml = file_get_contents("http://feeds.bbc.co.uk/weather/feeds/rss/5day/id/3616.xml"); 

$xmlObj = simplexml_load_string($xml);

$description = (string) $xmlObj->channel->item->description;
echo $description;
?>

As el_timm said. An alternative would be to use DOM:

$xml = new DOMDocument();
$xml->load("http:.....");
$xpath = new DOMXpath($xml);
$descriptions = $xpath->query("//description");

foreach($descriptions as $description)
{
	echo $description->nodeValue,"\n";
}
