I used ASBuilder.java to validate personal.xsd. If I remove the first
occurrence of the <xs:sequence> AND </xs:sequence>, it catches the error and
report the line/column numbers.
But if I just remove <xs:sequence> OR </xs:sequence> alone, it will through
exception as follows and not report the correct line/column number
correctly.
[Fatal Error] :-1:-1: The element type "xs:complexType" must be terminated
by the matching end-tag "</xs:complexType>".
java.lang.NullPointerException
at org.apache.xerces.parsers.DOMASBuilderImpl.parseASURI(Unknown Source)
at edu.gatech.xmlape.editor.dom.ASBuilder.main(ASBuilder.java:212)
So I guess the ASBuilder can't handle wellformedness problem?
the personal.xsd:
