Using DOM_NodeIterator

[KRAUSE,MIKE (HP-FtCollins,ex1)]

Hi,

 

I'm trying to use the DOM Level 2 DOM_NodeIterator class to iterate through a sub-tree.  I only want element nodes.  What I am getting are element nodes and #text nodes and I don't know why.  Here is what I'm doing:

 

class MyFilter : public DOM_NodeFilter {

  FilterAction acceptNode(DOM_Node node);

};

 

DOM_NodeFilter::FilterAction MyFilter::acceptNode(DOM_Node node) {
 if (node.getNodeType() == DOM_Node::ELEMENT_NODE) {
  return DOM_NodeFilter::ACCEPT;
 } else {
  return DOM_NodeFilter::SKIP;
 }
}

 

MyFilter filter;
DOM_NodeIterator iter=doc.createNodeIterator(parent_node, DOM_NodeIterator::SHOW_ELEMENT, filter);

 

DOM_Node node;       

while ((node = iter.nextNode()) != 0) {

  // Assuming that I get ELEMENT_NODEs only, but get #text nodes too!
}

Any ideas on why I'm getting the extra nodes here?

 

Regards,
