in thread How to remove empty XML elements using XML::LibXML

Thanks - that works perfectly when operating on 1.xml or another XML document object.

Your sample uncovered another layer/problem:

my XML document comes from Net::EPP::Frame ( says "This module implements a subclass of the XML::LibXML::Document..."), so I'm doing something wrong when I try:

use Net::EPP::Frame; my $frame = Net::EPP::Frame::Command::Update::Contact->new; #... my $xpc = XML::LibXML::XPathContext->new($frame); $xpc->registerNs('contact', 'urn:ietf:params:xml:ns:contact-1.0'); for my $name (qw(rem add)) { for my $node ($xpc->findnodes("//contact:$name".'[not(*|text() +|@*|processing-instruction()|comment())]', $frame->documentElement)) +{ $node = $node->parentNode->removeChild($node); } } print $frame->toString(1);

My thinking is that because Net::EPP::Frame inherits from XML::LibXML::Document, I should be able to operate on $frame (the XML document) similarly to your original solution... but I'm missing something.

    I have no experience with Net::EPP::Frame. What error do you get, or how is the output different from your expectations? Also, what does ref $frame say?

      Running my sample code produces no change at all, and no error. The offending XML elements are still there.

      ref $frame says
