User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.12) Gecko/20050920 Firefox/1.0.7
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.12) Gecko/20050920 Firefox/1.0.7
When using the getElementsByTagName DOM method on an element belonging to an XML
document an HTMLCollection object is returned although the DOM specs require an
NodeList object.
Moreover, having prototyped the HTMLCollection object with some specifics, these
are not available from the returned HTMLCollection object.
Reproducible: Always
Steps to Reproduce:
1. Load an XUL document in the browser.
2. Run the debugger and stop somewhere in order to apply the
getElementsByTagName method.
3. Have a look at the returned object.
Actual Results:
An HTMLCollection object is returned.
Expected Results:
A NodeList object should have been returned.
See bug 14869 and bug 300519.

Note that prototypes and the DOM don't mix -- the DOM assumes multiple inheritance, which cannot happen with prototypes.
