Detailed Description

The functions in this group allows you to create from scratch (or update) a XMLNode structure.

Start by creating your top node with the "createXMLTopNode" function and then add new nodes with the "addChild" function. The parameter 'pos' gives the position where the childNode, the text or the XMLClearTag will be inserted. The default value (pos=-1) inserts at the end. The value (pos=0) insert at the beginning (Insertion at the beginning is slower than at the end).

REMARK: 0 <= pos < nChild()+nText()+nClear()
