what's wrong with Xerces Parser????

[Elhanan]

it took me hours to figure out, i tested on ecplise a small java
application, that builds an XML dom, it returned the string using the
toStrimg method, however when i turned it into a Web Service under
tomcat 4.24 it returned null!! only then i noticed i was using
different parsers, the first, crimson (i think it came with axis)
worked find while the second (tomcat's) returned null, why??

Been there, done that, found the answer by searching in xerces docs for
deferred node implementations.

u mean by setting this:
http://apache.org/xml/features/dom/defer-node-expansion
to false?

but in order to change it to false
i'll need to change
http://apache.org/xml/properties/dom/document-class-name

to some other class (will is till work under tomcat?)

Please don't TOFU

No. There are good reasons to use defered nodes (although I can't
remember which

to some other class (will is till work under tomcat?)

If you want the xml as a string you should use a Transformer don't have
to know anything about the actual xml implementation, somthing like:

factory=TransformerFactory.newInstance();
transformer=factory.newTransformer();
transformer.transform(xmlSource, new StreamResult(out));
