That's what I want to do with Xalan: "tracing" the transformation process.
But, of course, I don't want to implement a complete debugger, just an output
if an element or something is requested and it doesn't exists. That's why I asked if somebody has expiereince with the Xalan debugging API, since there exactly this is implemented.

My problem is that I don't want to implement a real debugger and that I haven't any expiereince with the debugging API.
E.g. I don't know which event is passed to the TraceListener if a node was tried to be selected but it couldn't because the node doesn't exists... And I don't now how to find this special event in the haystack of events beeing produced...
