Ramprasad Kanumuru commented on XALANJ-2010:
--------------------------------------------
Hi ,
Thanks for looking into the issue. I am inlining the java code that
I used to execute the xsl. The output generated is:
Output Generated by getMessageAndLocation()
-----------------------------------------------------------------------
javax.xml.transform.TransformerConfigurationException:
javax.xml.transform.TransformerException:
javax.xml.transform.TransformerException: Empty expression!
Output Generated by getLocationAsString()
---------------------------------------------------------------
null
Ideally I want the getMessageAndLocation() to generate
; Line#: 68; Column#: 27 : Empty expression!
This error message would allow me to easily locate the problem, in this
case the 'if' construct without any expression ( <xsl:if test="">)
I believe the user will not be interested in the java exception stack
trace and it does not seem to be intuitive to show stack trace in the exception
message. Please correct me if I am wrong.
Thanks,
Ramprasad
