probably. the node::itertor function takes a function reference, which
is called for the node and all its child nodes. the function should 
take only a sinlge parameter, which will be the current node. 

example:
$node->iterator( sub { warn $_[0]->getName(); } );
warns all node names in a tree.

you can do this:
foreach $node ( $parent->getChildNodes() ) {
 ...
}

or

foreach $node ( $parent->getElementsByTagName( $tagname ) ) {
 ...
}


i hope this helps
