> When using SAX2XMLReader, an EmptyStackException is thrown when parsing a document whose top-level element has no grammar but which contains a lower-level element that has a schema associated with it. (Perhaps I have over-generalized -- example below.) XMLSpy is able to parse this document and, as far as I can tell, it should be valid. In any case, an EmptyStackException definitely seems to be out of order here.
> To reproduce the problem, parse this document instance:
> <?xml version="1.0" encoding="ASCII"?>
> <x>
> <test xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
> xsi:noNamespaceSchemaLocation="test.xsd"
> >1415926535</test>
> </x>
> with this schema:
> <?xml version="1.0" encoding="ASCII"?>
> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
> <xs:element name="test" type="xs:decimal"/>
> </xs:schema>
> using the SAX2Print example with no special arguments (valdation scheme = auto). When I do this, I get the following result:
> <?xml version="1.0" encoding="LATIN1"?>
> <x>
> <test xsi:noNamespaceSchemaLocation="test.xsd">1415926535</test>
> Fatal Error at file /u1/home/ejb/Q/bugs/xerces/empty-stack-exception/test.xml, line 5, char 19
> Message: An exception occurred! Type:EmptyStackException, Message:The stack is empty, cannot access members
> Ideally, a document should be able to contain any number of nested elements with schemas. This document:
> <?xml version="1.0" encoding="ASCII"?>
> <x>
> <test xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
> xsi:noNamespaceSchemaLocation="test.xsd"
> >1415926535</test>
> <y/>
> <test xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
> xsi:noNamespaceSchemaLocation="test.xsd"
> >7182818284</test>
> </x>
> should also be okay. With the validation scheme set to "auto", I expect to get schema validation errors reported for the "test" elements and well-formedness checking for the rest of the document. That part seems to be working in as much as I can introduce an error in the first test element and see the error reported with val scheme = auto.
> I will be traveling for the next 12 days, so I may not be able to be immediately responsive to responses to this bug report. When I get a chance, however, I will definitely do whatever checking is requested.
