Preloading schema that imports another schema
Hello,
I have a schema (in file 2.xsd) that imports another schema (in file 1.xsd)
and an instance document like this:
<?xml version="1.0"?>
<outer xmlns="http://localhost/test-2"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="file:2.xsd"
xmlns:sps-v1="http://localhost/test-1">
....
<inner xmlns="http://localhost/test-1"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="file:xml/1.xsd">
...
</inner>
</outer>
The interesting part is that if I explicitly preload only schema from 2.xsd,
the schema from file 1.xsd also get preloaded (I checked the pool contents)
and all works well when I parse the instance document. However, if I attempt
to preload both 2.xsd and 1.xsd, both of them are preloaded, as before, but
when I attempt to parse the the instance document I get this exception:
One of the grammar(s) returned from the user's grammar pool is in conflict
with another grammar.
I'm have used XMLSpy to validate the instance document and it validated.
Can anyone offer an explanation? TIA,
-a

I was not using 2.4.. thought I was. Anyhow I can now fetch it. Thanks a
lot.
Thanks,

Subject: RE: Get/Set Encoding value
Thanks for the information but I am a bit confused on to actually get the
encoding information. Do I need to implement the Locator interface and add
this method to the interface? If so, what do I return for the methods I
must implement as part of the Locator interface? Or am I way off base ? :-)
Thanks,
Rob

Hi Rob,
If you're using the latest version of the parser (Xerces 2.4.0), you
should be able to retrieve the encoding using SAX. Have a look at:
http://xml.apache.org/xerces2-j/faq-general.html#faq-8. The solution isn't
particularly elegant, but SAX's Locator2 interface isn't available yet.
Just to clarify some things for you:
<?xml ... ?> is an xml declaration. It isn't a processing instruction, so
it won't be reported to your ContentHandler.
SAX is read only, so if you need to change the encoding of your instance
document, you'd have an easier time using DOM. i.e. Parsing your document
(in whatever encoding) into a DOM, and then serializing it back with UTF-8
as the output encoding.
Hope that helps.

Get/Set Encoding value
Posted by Rob Outar <ro...@ideorlando.org>.
I have to write a program that will fetch the encoding information from XML
files:
<?xml version="1.0" encoding="UTF-8"?>
and verify that all encoding is set to UTF-8, my early trials using SAX has
not worked, I thought it was a preprocessing instruction but I did not get
the callback for my test files. Is there an easy way to fetch and possibly
update the encoding value?
Thanks,

No, from http://xml.apache.org/dist/xerces-j/. But!... with the jars from
the above location worked. Hmm! I have a problem - it's not easy to change
the parser used on the govenment project.
