in reply to XML::LibXML's findnodes is beahving weirdly

You have a default, unnamed namespace. This is a big annoyance in XML/XSL and may be causing your problem. All nodes without a namespace are in the Atom namespace, but its name is blank.

I know how to get around it using XSL, but not with the module.

In XSL, you need to make up your own namespace and call it as an attribute of the stylesheet, like xmlns:whatever="http://www.w3.org/2005/Atom". As long as it matches the URL in the input, all your content is in the "whatever" namespace if another namespace isn't specified.

But like I say, that may not be the problem.

    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;
