jaxp.TypeInfoWriter as an XSD 1.1 Validation Tool

This section provides a tutorial example on how to use sample program jaxp.TypeInfoWriter as an XSD 1.1 validation tool. It prints out element type information, while it is parsing through the XML document. Error messages are printed out where and when they occurred.

If you want to see XSD 1.1 errors printed inside the XML element structure, you can try the other sample program, jaxp.TypeInfoWriter:

herong> java_xerces jaxp.TypeInfoWriter -xsd11 -i xsd11_datatype_test.xml

setDocumentLocator(systemId="file:///C:/herong
^^^ /xsd11_datatype_test.xml", publicId=null)
startDocument()
 startElement(name="XSD11_Datatype_Test",type=
^^^ "#AnonType_XSD11_Datatype_Test",attributes={{name=
^^^ "{http://www.w3.org/2001/XMLSchema-instance}
^^^ noNamespaceSchemaLocation",type="{http://www.w3.org/2001

  startElement(name="AnyAtomicType",type="{http://www.w3.org/2001

  endElement(name="AnyAtomicType")
  startElement(name="AnyAtomicType",type="{http://www.w3.org/2001

  endElement(name="YearMonthDuration")

endDocument()

Excellent! jaxp.TypeInfoWriter is good XSD 1.1 validation tool. It prints out element type information, while it is parsing through the XML document. Error messages are printed out where and when they occurred.
