If you want to see how XML parser handles XML document with Schema validation from socket connections, you can try the socket\DelayedInput.java provided in the Apache Xerces package to display element type information.

Run socket\DelayedInput.java with "-v -s" option, if you have Apache Xerces 2.11.0 installed:

\fyicenter\xerces-2_11_0\samples>\fyicenter\jdk-1.8.0\bin\java 
   -cp .;..\xercesImpl.jar socket.DelayedInput -v -s UserXsdError.xml
