Hello Everyone,

I have a slight problem when using XMLBeans.

I created a schema in which one of the elements has tag "Constant". It is
used like so:

<Constant name="PI" value="3.142" type="number"/>

The schema defines this element to be of type "TConstant". When using
scomp.exe, this generates the interface

TConstant

and the implementation class

TConstantImpl

Now, I execute an XPath query that returns a DOM "Node" using JAXP. I then
parse the returned node. For example,

Node node = XPath.evaluate("//Constant[name="PI"]", new InputSource("foo.xml"),
XPathConstants.NODESET);
TConstant constantdecl = TConstant.Factory.parse (node);

So far so good. If I do

constantdecl.toString()

I get

<Constant name="PI" value="3.142" type="number"/>

which is correct. However, if I use any of the generated methods for
retrieving the attributes such as getType(), getName() or getValue(), I keep
getting null. The XML returning methods like xgetType(), xgetValue(),
xgetName() also return null.

I am not sure why this is so. If the toString() method is able to recreate
the XML correctly, I think it should be reasonable to expect the attribute
value retrieval methods to return the correct values.

Any help will be appreciated!

Thanks,

Vijai.
