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)); Bugzilla: http://nagoya.apache.org/bugzilla/ Thanks for reporting this! Dave "Victor S. Popov" To: <[email protected]> <[EMAIL PROTECTED] cc: ign.ru> Subject: XalanC++ (Segmentation Fault) 01/22/2002 08:54 AM Please respond to victor 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"; }; } BT: Program terminated with signal 11, Segmentation fault.
