asked on

XML::LibXML and Xpath syntax How do I get attribute of sibling

This is follow on fromThis Question

In the xml bellow I need to locate the next 'link' after I've located 'images' within the parent 'entry'


I found this link that suggest can use "following-sibling" can someone see what I've  done wrong?  

note I've striped the xml down to simplify

Perl script
 
!C:\strawberry\perl\bin\perl.exe

use strict;
use warnings;
use XML::LibXML;
use XML::LibXML::XPathContext;
use Data::Dump qw(dump);


my $filename = 'georss.xml';

my $dom = XML::LibXML->load_xml(location => $filename);
my $xpc = XML::LibXML::XPathContext->new($dom);
$xpc->registerNs(dft => "http://www.w3.org/2005/Atom");
$xpc->registerNs(georss => "http://www.georss.org/georss");


foreach my $Entry ($xpc->findnodes("//dft:feed/dft:entry")) {

     foreach my $Images ($xpc->findnodes("/dft:title[not(\@type='text')]", $Entry)) {
         my $ImageVal = $Images->textContent;

          ####  This finds all the Images
         print "ImageVal $ImageVal\n";
         my $link = $Images->following-sibling::link[\@href];
         print "link $link\n";
         
     }

}
