> I recently updated my axiom runtime, and promptly ran into a problem where I could not retrieve a child element I expected to be able to retrieve when calling OMElementImpl.getChildrenWithName. It turns out this is due to a change in
> org.apache.axiom.om.impl.traverse.OMChildrenQNameIterator
> was changed in rev 522259 to be quite a bit more restrictive in establishing matches with the QName parameter. Formerly, the code treated a null or empty namespace and a null or empty localname as "match any namespace" or "match any localname." The new code uses QName.equals, which forces a match of both namespace and localname, regardless of null or empty values. From the QName.equals javadoc:
> "Two QNames are considered equal if and only if both the Namespace
> URI and local part are equal. This method uses String.equals()
> to check equality of the Namespace URI and local part. The prefix is NOT
> used to determine equality. "
> The javadoc for OMElementImpl.getChildrenWithName. says:
> "Searches for children with a given QName and returns an iterator to traverse through the OMNodes. The QName can contain any combination of prefix, localname and URI."
> link: http://ws.apache.org/commons/axiom/apidocs/org/apache/axiom/om/impl/llom/OMElementImpl.html#getChildrenWithName(javax.xml.namespace.QName)
> Seems like the old code was right if I interpret that "any combination" statement in the javadoc correctly. If there is no objections, I'd like to revert the OMChildrenQNameIterator to the pre-522259 code.
> Please see patch if necessary.
