Sure. You can write your own ErrorListener. Details depend on the API 
you are using; if it's JAXP, this is a run-time error, so the 
ErrorListener in question is the one you nominate to the Transformer 
object. (For compile time errors, you would have to set the 
ErrorListener on the TransformerFactory, though for Saxon, you can 
specify a different ErrorListener for each compilation by using 
Saxon-specific interfaces).

Alternatively, you can get the ErrorListener that Saxon is using, cast 
it to net.sf.saxon.lib.StandardErrorListener, and then call its 
setErrorOutput() method to set a different output destination.

Just remember that you need to consider both compile-time and run-time 
errors, and the mechanisms are slightly different.
