Can someone please confirm that [DOMNodeIterator nextNode] shouldn't
be returning items outside of the root node that is passed into
createNodeIterator.
E.g. Consider the following snippet from Apple's Mac OS X web page
(http://www.apple.com/macosx/):
(In its original form:)
<a href="/macosx/features/dashboard/"><img src="http://
images.apple.com/macosx/features/dashboard/images/
indexdashboard20050412.jpg" alt="Dashboard Widgets" width="440"
height="275" border="0" class="across"></a>
<p class="sosumi"><strong><a href="/macosx/features/
dashboard/">Dashboard</a>.</strong> Zooming to the top of your
Desktop with the click of a function key, Dashboard, like
Exposé, disappears just as easily. Use Dashboard to access nifty
new mini-applications called widgets.</p>
When I do the following:
DOMNode* rootNode <== This is set to the first <a> element above
DOMNodeIterator* iterator = [ownerDoc
createNodeIterator:rootNode :DOM_SHOW_ALL :nil :NO];
DOMNode* node;
while ((node = [iterator nextNode]) != nil)
;
I get all of the nodes from rootNode until the end of the document
and not just the <a> and the <img> as expected.
This isn't always the case (i.e often it works as expected) but in
this case it gets it wrong.
In this failing case, I have confirmed that the DOM itself has the
right hierarchy.
This is with both the 418 WebKit and a recent TOT.
If someone could please confirm that this behaviour is not intended
so i can file a proper bug report.
FYI - My simple workaround was:
DOMNode* rootNode <== This is set to the first <a> element above
DOMNode* badIteratorCatcher = [rootNode nextSibling] ? [rootNode
nextSibling] : [rootNode parentNode];
DOMNodeIterator* iterator = [ownerDoc
createNodeIterator:rootNode :DOM_SHOW_ALL :nil :NO];
DOMNode* node;
while (((node = [iterator nextNode]) != nil) && (node !=
badIteratorCatcher))
;
