Hi Vineet. Sounds like a regression to me.
We'll need some way to reproduce it.
Is it possible that Joe could call you to try and work out next steps? It
may require a debugger session on your end with Joe on the phone asking
questions.

something strange in using xalan 2.2.0 / 2.3.0
Please respond to
xalan-dev
Hi !
� � � � We at Trilogy, use xalan for xslt purpose. When i started migrating
from xalan 2.2.D13 (xerces 1.4.4) to 2.2.0 / 2.3.0, I ran into a problem.
We have an xml and an xsl and the code generates 65 html files using the
xml/xsl. The generation works perfectly fine with the 2.2.D13 but when i
used 2.2.0 it generated 6 files correctly and the seventh file threw and
exception in XRTreeFrag.xstr(). When i used 2.3.0 it generated around 10
files and then threw the similar exception (trace shown below). When i
changed the following lines
� � � if(null == m_xmlStr)
� � � � � � � �m_xmlStr = m_dtm.getStringValue(m_dtmRoot);
in xstr()
to
� � � if(m_xmlStr == null)
� � � � � � if (m_dtm != null)
� � � � � � � � m_xmlStr = m_dtm.getStringValue(m_dtmRoot);
� � � � � � else
� � � � � � � � m_xmlStr = new XString("");
in 2.2.0 the generation of all the 65 files was perfect. Basically the
m_dtm was null at that point. Please let me know if there is some syntax
problem in the xsl file which was ignored/taken-care-of in 2.2.D13 but does
need to be correct from 2.2.0 onwards ? or is this really some kind of bug
in the code ? Can you point out directly as what in xsl could be wrong ? Is
it an xpath issue (some xpath not following the norms?)
This is really critical to our development and we have a release soon. We
would appreciate if you could get back to us asap. The xsl file is really
huge (5000 lines) and due to copyright issues I cannot send it to you.
Thanks,
