reading xml content from a url

You can just use:

$xml = file_get_contents('http://domain.com/xmlfile.xml');

-r-

<?php
$xml = file_get_contents('http://preisvergleich.guenstig.de/xservice/getCategoryList.do?version=2.3');
?>

iam tryign to read like this it throws errors

thatz the url from where i need to read the xml content and i want the seperated content

What kind of errors. The url seems to work for me.

-r-

Warning: file_get_contents(): php_network_getaddresses: gethostbyname failed in D:\guenstig\guenstig1\gunxml.php on line 4

Warning: file_get_contents(http://preisvergleich.guenstig.de/xservice/getCategoryList.do?version=2.3): failed to open stream: No such file or directory in D:\guenstig\guenstig1\gunxml.php on line 4

this is the error it gives to me

i kept the allow_url_fopen- on in php.ini file but still i get the same error.

but i want to know after reading the file using file_get_contents how can i get the seperated content like we have starting tag ending tags <itmes></itmes> so i want all the contents of this xml contents
