[ http://issues.apache.org/jira/browse/XERCESC-1418?page=comments#action_65279 ] Frank Gierschner commented on XERCESC-1418: -------------------------------------------
Me once again. I forgot to mention that the in-memory xml data (seen at the end of my description and contained in XMLByte * buf in buildDOMDocument()) was generated via serialization by DOMWriter::writeNode() from the created DOMDocument here for testing issues. > Failure to assign/relate an in-memory schema to an in-memory xml > ---------------------------------------------------------------- > > Key: XERCESC-1418 > URL: http://issues.apache.org/jira/browse/XERCESC-1418 > Project: Xerces-C++ > Type: Bug > Components: Validating Parser (Schema) (Xerces 1.5 or up only) > Versions: 2.6.0 > Environment: Windows2000 > Reporter: Frank Gierschner > > Hi. > I wish to schema-validate an in-memory xml-string, coming in from a CORBA > client, against an in-memory schema. But the parser (DOMBuilder) does not > seem to associate the xml-data with the provided schema.
