in reply to How to parse xml with namespase value in XMl:LibXML?

Its simple, define the namespace in an xpathcontext -- isn't xml/xpath fun :)

It also helps to have valid xml

      But when I am trying to access the nodes as below I don't get any value. 
      print $chapter_node->findvalue('./book:locator/@xlink:href') . "\n";

      Could you please elaborate a bit or point out where I am committing mistake?

        Works for me: 
        #!/usr/bin/perl
use warnings;
use strict;

use XML::LibXML;

my $xml  = XML::LibXML->load_xml(IO => *DATA);
my $root = $xml->documentElement;
my $chapter_node = $root->findnodes('book:chapter')->[0];
print $chapter_node->findvalue('./book:locator/@*') . "\n";

__DATA__

+l data -->

        Note the changes I made to your data. Maybe your $chapter_node contains something else?

        Well, no, you don't show self-contained code . I guess that you didn't read my nodes and setup xpc with some setns, but I don't really have any way of knowing; also, I hate xml
