XalanTransformer::transform question

[Endre Magyari]

Dear List,         I would like to write two functions, both based on Xalan, with this signatures:      XMIToUdm(const istream& in, ostream& out);  UdmToXMI(const istream& in, ostream& out);   The XSLT files for these functions are available in separate files. (Udm2Xmi.xslt, Xmi2Udm.xslt).   I wonder how to do this? I've seen the source of the XalanTransformer, and I have also seen that filenames are passed there to transform(), as char * -s.   My questions: - How gets a XalanParsedSource constructed from a char * - How could I construct a XalanParsedSource from an istream,or is there an other way ( other function) which accepts streams as input and output arguments ?   Thank you, Endre
