Hello,
I am working with Xercesc 2.7.0 in a VxWorks environment. In general it works
fine
but there is a problem with one certain XML-file, where the parser does not
return, i.e. it looks
like the parser runs into an endless loop. The schema file has some type
definitions for
elements (e.g. "Dig_InOut_Type"). These elements are not generally required and
in the
attached XML file they are missing (see comments starting with "e.g.").
XML and schema file are set up with XML Spy.
I tried to parse this file with the Xercesc Windows version and the behaviour
is the same.
Is this a known problem ? What may be wrong with my code ?
Attached is the source code for parsing and the XML and Schema file.
Regards
Jörg
