XML to complex/deep ABAP structure

Has anyone successfully used Function module

SDIXML_DOM_TO_DATA (& related SDIXML* Function modules) to convert XML string into complex ABAP structure?

I am using WAS 6.40 (ECC) and I was hoping that if the XML & the ABAP structure you pass as function module parameter do match in strcture, then this Function module should automatically convert (ie, de-serialize) the XML into ABAP structure - Without having to write any XSLT or ST (Simple Transformation) files !

Any ideas? Any other Function module? The ABAP structure I want to be populated is a "deep structure" with many levels and tables at various levels etc..

Thanks a lot
