Extract metadata from an xml

[ofuuzo1@yahoo.no]

The below xml is generated when I make a remote call like:

?php
$url = "http://......./oai?
verb=ListRecord s&metadataPrefi x=frida&set=UUI ";
$input = @file_get_conte nts($url) or die('Could not access file:
$url');
echo $input;
?>
How can I extract only
<resumptionToke n completeListSiz e="14" cursor="0">set+ UITO+cls
+14+cursor+3+la st+110547</resumptionToken >

and put it in a variable?

Thanks in advance.
