[XML-DEV Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] Re: Problem parsing XML file with Xerces-J
First of all I am happy to report that I have solved the problem by
pre-editing the XML string. My application now works fine.
I simply used substring function as below to strip the DTD reference
rsp = rsp.substring(rsp.indexOf("<MESSAGING>"));
But I am *eager* to learn the EntityResolver approach.
I have not done anything special. I have just extended my class with
SAX class DefaultHandler.
I then set my class object as the EntityResolver handler for the
DocumentBuilder as -
builder.setEntityResolver(obj);
JDK 1.4.2 document says -
"
EntityResolver is a default base class for SAX2 event handlers.
This class is available as a convenience base class for SAX2
applications: it provides default implementations for all of the
callbacks in the four core SAX2 handler classes:
1) EntityResolver
2) DTDHandler
3) ContentHandler
3) ErrorHandler
"
So I think simply this should have worked; but it is not working..
As another solution for EntityResolver approach(without doing anything
as above), I called setEntityResolver method(with argument null) on
the DocumentBuilder object. The JDK document says about this..
"
Specify the EntityResolver to be used to resolve entities present in
the XML document to be parsed. Setting this to null will result in the
underlying implementation using it's own default implementation and
behavior.
"
But this also does'nt work.
What do I need to do to set the EntityResolver correctly?
Best regards,
