Joining two tree structures, hmm, that's a little vague.

If you're uncertain how to use the method, just take a look at *importNode* and *adoptNode* in XML::LibXML::Document, and maybe also at this example:


$ cat import-node.pl 
use common::sense;
use XML::LibXML;

my $parser = XML::LibXML->new;
my $doc  = $parser->parse_string( '<Urmel><a/><b/><c/></Urmel>' );
my $doc2 = $parser->parse_string( '<Urmel><D/><E/><F/></Urmel>' );

my @nodes = $doc->getElementsByTagName( 'b' );
for ( @nodes ) {
    my $imported = $doc2->importNode( $_ );
    $doc2->documentElement->appendChild( $imported );
}
print $doc2->toString;


$ perl import-node.pl 
<?xml version="1.0"?>
<Urmel><D/><E/><F/><b/></Urmel>


You can see that <b> has been imported.
