& XSLT my $parser = new XML::LibXML();
my $doc = $parser-> parse_string($xmp);
# or:
# my $doc = $parser-> parse_file($xmp_filename);
my $rootNode = $doc-> documentElement();
my $image = $rootNode-> findvalue('//xapgimg:image');

Or if you want to be more specific, you can use the following for the 
last line:
my $image = 
$rootNode-> findvalue('/x:xmpmeta/rdf:rdf//xap:thumbnails//xapgimg:image');

This code assumes that only one thumbnail exists.  However, it should 
suffice.

The above code illustrates using XPath to query the contents of the XML 
file.  You may want to look into XPath more, because it is a very 
powerful way of interacting with XML documents, and would let you get 
more out of this document easily if you need to.
