I wrote a Java class which implements the DOMErrorHandler interface (Xerces).
This class aims at validating an XML instance against
an XML schema. The parser used to parse and
compare the schema and the XML instance is a DOMASBuilder (Xerces).
When the XML instance doesn't fit to the XML schema, a DOMError is thrown and
processed by a handleError method which code looks
like :
public boolean handleError(DOMError error)
{
System.err.print("[");
switch ( error.getSeverity() )
{
case DOMError.SEVERITY_WARNING:
System.err.print("Warning");
break;
case DOMError.SEVERITY_ERROR:
System.err.print("Error");
break;
case DOMError.SEVERITY_FATAL_ERROR:
System.err.print("Fatal Error");
break;
}
System.err.print("] ");
...
// Node in error -> NODE IS ALWAYS EMPTY !!??
DOMLocator domLoc = error.getLocation();
Node errNode = domLoc.getErrorNode();
if ( errNode != null )
{
String strNodeName = errNode.getNodeName();
String strNodeValue = errNode.getFirstChild().getNodeValue();
}
return error.getSeverity() != DOMError.SEVERITY_FATAL_ERROR;
}
My problem is that I can't get the XML instance's node in error. The
DOMError.getLocation().getErrorNode() instruction should return
a reference to the node in the XML instance which
doesn't respect the grammar in the schema. This reference is always a null
pointer ! Does anybody know which parameter/option should
I set to get the information on the node in error ??
Thanks a lot.
