There's no point saying it's urgent. It makes people less inclined to help you if they think you're in a panic. At least take the time to write in proper sentences, rather that stream of consciousness.
I'm afraid I simply don't understand your question. The terminology is all wrong. What do you mean by "converting the xslt to xml"? XSLT already is XML. Perhaps you just mean you want to run the transformation from a Java application? In that case look at the JAXP interfaces.
