[NTG-context] xml tree extension?

Is it possible to have the following order of actions? <root> <file name="filename1"> <file name="filename2"> .. </root> The file contains an xml-tree starting at <fileroot>.. At the moment I am processing the files with \xmlprocessfile{fileroot}{filename}{}, but this generate separate node-lists for <root> and <fileroot>; at least, that is my understanding of its workings. Can I change the processing in such a way that something akin the following tree structure is processed, each time with a new file: <root> <file name="filename1"/> <fileroot> .. </fileroot> <file name="filename2"/> <fileroot> .. </fileroot> .. </root> Or is it impossible to accomplish?
