* TQDomElement e;

* Also note that localName is the part without the prefix, this is the whole point
* of namespace-aware methods.
*
* To find the attribute with a given name, use TQDomElement::attributeNS.
*
* Do not use getElementsByTagNameNS, it's recursive (which is never needed in KOffice).
* Do not use tagName() or nodeName() or prefix(), since the prefix isn't fixed.
