Detailed Description

Helper class for xml files used to store ssc/cx data.

Both the xml document and filename are stored, and save/load are provided.

Several instances of the same file points to the same internal object, in the same way as QSettings. This means that they share the QDomDocument, and is NOT threadsafe.

The object has a current element, which is used to ease work at a specified level in the hierarchy. Use descend/ascend to change the current element.

The getElement() methods are used to retrieve QDomElements relative to the current element.
