ATTLIST id ID not working?

[eric]

Greetings!

Not sure if this is the right place to post this or if I should post in the
Java newsgroup.

I have a DTD which specifies:

<!ATTLIST category id ID #IMPLIED>

In my xml document I have:

<category id = "Barber and Beauty Salons">
..
..
..
<category id="Attorneys">
..
..
..
<category id = "Florists">

My thinking is that the DTD has specified id as a unique ID.

When I try this in my jsp page:

Element test = doc.getElementById("Attorneys");
out.println("Testing " + test);

All I get for test is null. Is this a feature, bug or somthing I'm doing
wrong? :-))

ID-attribute values cannot contain spaces. See

This does not match the production rules for ID (contains whie space).

Hmm, maybe you're not parsing with validation switched on.

Johannes,

Thanks for pointing out the whitespace! It did not make any difference
though.

I should have put this in my original post. Here's how I set up the
validation:

DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setValidating (true);

if(dbf.isValidating())
out.println("It is validating <br />");

I get no errors and the out.println displays. I wonder why the white space
in the id wasn't caught?

Still getting null for doc.getElementById("Attorneys");

Hello Eric,

Try the following print statement instead.

Element test = doc.getElementById("Attorneys");
out.println("Testing " + test.getNodeName());

We've run into the same problem before. Usually I would expect the
Java object value to be printed, but it always returns a null for XML
Node objects.

Check the API for the Node class for a table of values that will be
returned depending on the method called for a specific implemenation of
the Node class.

Kind regards,
Eric
