Re^2: XML::LibXML's findnodes is beahving weirdly

[un-chomp]

You can use XML::LibXML::XPathContext to register the namespace as follows:

use strict;
use warnings;

use XML::LibXML;
use XML::LibXML::XPathContext;

# load the XML doc
my $p = XML::LibXML->new;
my $xml_file = do { local $/; <DATA> };
my $dom = $p->parse_string( $xml_file );

# register the namespace
my $xc = XML::LibXML::XPathContext->new( $dom );
$xc->registerNs('ns', 'http://www.w3.org/2005/Atom');

# select using XPath
my @nodes = $xc->findnodes( '/ns:feed/ns:entry');
print $_->toString for @nodes;
