Is xslt processor avalable by uno service

I am going to make a xslt from data in Calc. Really I need to replace some data in ready xml files. XSLT would be a good here. I played with xslt filters, it works, but not enough for me. I’d do it from macros. I think it is possible to use XSLT processor by UNO servise, but I have not found any template or even comprehensive docs. I’m new for UNO. Can you help me to find any appropriate template for BASIC or C++ or any. Or reference to any docs concerning. Thank you.
