Thanks, David!
The workaround works fine!
We're looking forward for the bug to be fixed.

Subject: Re: XalanC++ (Segmentation Fault)
I've verified this as a problem. Can you please post a bug in Buzilla so
we can track this? There's an easy work-around in your code -- just set
the system ID for the input sources to a dummy value:
const XalanDOMString theSystemID("Stream input");
xml.setSystemId(c_wstr(theSystemID));
xsl.setSystemId(c_wstr(theSystemID));

Thanks for reporting this!

Hi!
We are trying to use XalanC++ to transform XML to HTML. I've tried to use
string streams as input sources and got "Segmentation Fault" in case of
invalid XSL-source by the means of structure, i.e. no exception was thrown.
Nevertheless when I use files with the same sources (invalid XSL) instead
of
streams, it works - transformer treats the error normally. Here is the code
of prototype:
XML:
<?xml version="1.0"?>
<document attribute="Test"/>
XSL:
<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:value-of select="."/> <!-- structural trap -->
<xsl:template match="/">
<html><body>Test</body></html>
</xsl:template>
</xsl:stylesheet>
CODE:
{
istrstream xml_stream (xml_text, strlen (xml_text));
istrstream xsl_stream (xsl_text, strlen (xsl_text));
XalanTransformer xalan;
XSLTInputSource xml (& xml_stream /* "xml.xml" */);
XSLTInputSource xsl (& xsl_stream /* "xsl.xsl" */);
XSLTResultTarget output (cout);
try {
if (xalan.transform(xml, xsl, output) != 0)
cout << xalan.getLastError () << endl;
} catch (...) {
cout << "ERROR";
};
}
