The question makes no sense. XML sample or even an XML schema does not define XSL transformation (I hope you know that it means Extensible Stylesheet Language,
http://en.wikipedia.org/wiki/XSL[
^]).
XSL is designed to transform some class of XML document to some output, XML, plain text, HTML (very usual application), something like that. XSL is a function having XML on input and generating some output. It is theoretically impossible to restore some general function by finite set of input + output samples. However, it is sometimes possible to recreate such function based on set of samples (even one sample), with limited robustness. Such algorithms do exist.
But even if you already had such algorithm, you would need to supply samples of both input and output, not just XML. That's why this question makes no sense.
