Woops -- where did that bogus address come from? Let me try again: _____

Sure! This program from c:/dev/xalan/xalan-j_2_7_1/samples/UseStylesheetPI/UseStylesheetPI.java (see attachment) does not work because I made a minor modification to read from standard input on line 58. Can you help me make it work? Here is the fragment redundantly for your reding pleasure. Note that if I hard code a file name on line 58, line 62 works. Thanks!

Well, it's possible -- but you'd need to develop your own data stream protocol which allowed you to express logical end-of-file, and do some entity-resolver work to read twice from this delimited stream using different URIs. Or, simpler but less efficient, have a preprocessing stage which reads that delimited stream, writes the documents into scratch files, and then process from those. But I agree that we're guessing at the intended meaning. Siegfried, maybe you ought to take a long step back and explain exactly what it is you're trying to do. If you want to read both the stylesheet and document from stdin, you need a delimiting and resolver solution as discussed above. If you just want to read the document from stdin, and the stylesheet from a file, while writing to stdout... well, that should be a trivial change to one of the Xalan sample programs. If you're trying to do something else, you'll need to explain what in enough detail that we can advise you. The mind-reading support service costs real money. <smile/>
