Please have a look at How do I post a question effectively? - you haven't given a runnable piece of code, the expected output, and the current output.

You seem to want to avoid passing the document object around like it's a bad thing - it's not, in fact, if I understand your question correctly, then the solution is based on that you will need to pass the XML::LibXML::Document object around and add your elements to the document as you create them, instead of handling unbound nodes.

use warnings;
use strict;
use XML::LibXML;
my $doc = XML::LibXML::Document->new;
my $el1 = $doc->createElementNS("namespace0","aaa");
$el1->setNamespace("namespace1","p1",0);
$el1->setNamespace("namespace2","p2",0);
$doc->setDocumentElement($el1);
my $el2 = $doc->createElement("bbb");
$el2->setNamespace("namespace2","p2",1);
$el1->appendChild($el2);
my $el3 = $doc->createElementNS("namespace0","ccc");
$el1->appendChild($el3);
my $el4 = $doc->createElement("p1:ddd");
$el3->appendChild($el4);
print $doc->toString(1);

__END__

<?xml version="1.0"?>
<aaa xmlns="namespace0" xmlns:p1="namespace1" xmlns:p2="namespace2">
  <p2:bbb/>
  <ccc>
    <p1:ddd/>
  </ccc>
</aaa>

Note how the namespace declarations are automatically reused. This is actually documented in XML::LibXML::Element's setNamespace. Since you seem to want to work with XML::LibXML more closely, I strongly suggest you take the time to read all of its documentation (starting with XML::LibXML::Node, XML::LibXML::Element and XML::LibXML::Document).
