Description
The method QDomElement QDomDocument::elementById(const QString &elementId) is implemented and documented as this:
/*!
Returns the element whose ID is equal to \a elementId. If no
element with the ID was found, this function returns a
\l{QDomNode::isNull()}{null element}.
Since the QDomClasses do not know which attributes are element
IDs, this function returns always a
\l{QDomNode::isNull()}{null element}.
This may change in a future version.
*/
QDomElement QDomDocument::elementById(const QString& /*elementId*/)
{
qWarning("elementById() is not implemented and will always return a null node.");
return QDomElement();
}
First, I do not see a reason to have a method which does nothing, especially not what one expects it should do.
Second, why is it not implemented? I understand that xml has no defined id attribute, but that could be given as a second parameter, defaulting to id, which presumably most people use:
QDomElement QDomDocument::elementById(const QString &elementId, const QString& idAttribute = "id")
