           Summary: nodeIterator with filter fails on documents not in a
                    frame
           Product: WebKit
           Version: 526+ (Nightly build)
          Platform: Macintosh
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: HTML DOM
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: simon.fraser at apple.com


I'm trying to use node iterators on an XML document fetched via XMLHttpRequest,
like this:

function subElementWithNodeName(inElement, inName)
{
  var upperName = inName.toUpperCase();
  var iter = document.createNodeIterator(inElement, NodeFilter.SHOW_ELEMENT,
null);
  var curNode;
  while (curNode = iter.nextNode())
  {
    if (curNode.nodeName.toUpperCase() == upperName)
      return curNode;
  }
  return null;
}

However, iter.nextNode() always returns null right away, without giving back
child elements of 'inElement' (which do exist).

Some debugging reveals this:

short JSNodeFilterCondition::acceptNode(Node* filterNode, JSValue*& exception)
const
{
    // FIXME: It makes no sense for this to depend on the document being in a
frame!
    Frame* frame = filterNode->document()->frame();
    if (!frame)
        return NodeFilter::FILTER_REJECT;

....

which is where it fails.
