you said XML twig allows it, but how?
The idea is to check if there's a root and if there's a root, then add the child node to it and then the data nodes as child nodes to that node.

How would i achieve this using Twig, i checked it's tutorial and my head's spinning faster than a top.

I dun mind using XML::SIMPLE, XML::WRITER, XML::TWIG, XML::SMART, XML::DUMPER...anything that lets me create a XML file and then open it at a later instance to add another node.
