Simple decision process within a schema

[Nicholas Taylor <Ni...@msdw.com>]

Hi,

I'm not sure whether this is the correct forum, but here goes. I would
like to be able to use a schema that will allow me to make decisions on
the content of an xml message depending on the values of certain fields.

For example:
If I have a message that consists of:
<Message>
  <field 1/>
  <field 2/>
  <field 3/>
</Message>

where <field 1/> would be an enumeration that could only contain A or X.

If <field 1> contains an A, I would like both <field 2> & <field 3> to
be mandatory.  If <field 1> contains an X, then <field 2> is still
mandatory and <field 3> is optional.
Is it possible to construct a schema that would allow you to perform
such a function?

Thanks,

Nicholas Taylor

DocumentBuilder-Problem

[Erik Zimmermann <ez...@pironet.com>]

Hi Everybody,
I m having a problem with a very simple piece of code. It throws an
exception which I cant explain.
Does anybody has an idea? (I didnt include the whole code...)


import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;

{
    System.out.println("Line 1");
        DocumentBuilderFactory docBuilderFactory =
DocumentBuilderFactory.newInstance();
    System.out.println("Line 2");
        DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();

    System.out.println("Line 3");
}

Line 1
Line 2
