 xmlGetNode(Int/Double/String) functions, when more than one node need to be
 gathered from a parent node it is advised to get the id of the parent node
 and work from there. This is because the XML-id holds the boundaries of the
-(parent)node which limits the searching area causing improved searching speed.
