/**
|
|
* This namespace contains a few convenience functions to simplify code using TQDom
|
|
* (when loading OASIS documents, in particular).
|
|
*
|
|
* To find the child element with a given name, use KoDom::namedItemNS.
|
|
*
|
|
* To find all child elements with a given name, use
|
|
* TQDomElement e;
|
|
* forEachElement( e, tqparent )
|
|
* {
|
|
* if ( e.localName() == "..." && e.namespaceURI() == KoXmlNS::... )
|
|
* {
|
|
* ...
|
|
* }
|
|
* }
|
|
* Note that this means you don't ever need to use TQDomNode nor toElement anymore!
|
|
* 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.
