How to add new node to the document and attach it with its correct
PSVI ?
Hi,
I'm working on a UI application that lets the user edit the xml
document based on the grammar specified in its schema. At first I don't know
how to add a new node using XERCES. Second when I add new node using the
normal DOM APIs, I can't get the schema information (PSVI) so I wanna ask
how to add new node to the document and attach it with its correct PSVI.
I don't know it there are APIs to re-validate the document so that I can
attach new nodes with its PSVI.
Best regards,
Omar Mostafa

You should be looking at the *source code* of the samples. They're
primarily meant to educate developers on how to use the APIs, not so much
for direct consumption by your application.

I have been searching the mailing list for the past two days with no clue.
Regarding the samples, I don't understand it, like "java
jaxp.SourceValidator (options) ..." how could I use this in my code ??
Thanks in advance,

No. You must be thinking of *JAXB*. That's something entirely different and
not supported by Xerces.
Please take a look at the samples and FAQs in the documentation. If you're
still not sure after reviewing that I suggest that you search the mailing
list archives [1] where you'll find many past discussions on DOM and PSVI.

The JAXP samples will generate the data access classes and the beans that
represent the grammar specified in the XSD, am I right ?
What I want to do is to get the PSVI dynamically while my application is
running.
I hope it's clear now.

I have no idea what you mean by that.

You need to re-validate the document and you can do that using JAXP. Take a
look at the sample.

Thanks Michael for your prompt response.
But I want to do this in the runtime not using JAXP. The typical scenario I
want to do is to add a new node at the runtime and use its
type definition as well.
The problem is that the PSVI gets created at the document loading time and I
can't create a new ElementPSVI and set the type definition.

Hi Omar,
You need to validate the document in order to get PSVI. The
jaxp.SourceValidator sample [1] included with Xerces shows how you can
validate a DOM using the JAXP Validation API.
Thanks.
