Help Required Urgently: Found something strange in using xalan 2.2.0 / 2.3.0
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,
