hi monks, please help me out in finding a solution. i want to list out each and every node of a xml document. if you guys can tell me this solution through xml::libxml that would be nice.

I'm pretty sure you already got exactly that, what is the problem?

for (//* | //@* | //comment() | //text() | //processing-instruction())
+ ls . ;

This example should do the trick. Note that DTD nodes don't appear in the XPath model, so I grep for those first.

use 5.010;
use XML::LibXML 1.70 ':all';

my $dom = XML::LibXML-> load_xml(IO => \*DATA);

my @nodes = (
    (grep { $_->nodeType ==  XML_DTD_NODE } $dom->childNodes),
    $dom->findnodes('//node() | //@*'),
    );    

foreach (@nodes) {
    say "Node name: ", $_->nodeName;
    say "Node path: ", $_->nodePath;
    say "---";
}

__DATA__
<!DOCTYPE foo>
<foo>
    <?processing-instruction?>
    <!-- a comment -->
    <bar attr="1" />
</foo>
