You aren't showing enough of your perl code to figure out how $node is set.

The error tells you that $node is an instance of the class DOMNodeList
- which has no hasChildNodes() method - it is a list of nodes not a
node, you will have to iterate through the list. Methods that return a
DOMNodeList object can be forced to return a simple Perl array if you
prefer:

   $dom_list_obj = $node->getChildeNodes() # return DOMNodeList object

  @node_list = $node->getChildeNodes() # return Perl array of DOMNodes

calling it in a scalar context gives you the Xerces List object,
calling it in an array context gives you a Perl list.

HTH, jas.
