I have copied your schema and document and attempted validation using Xerces
2.2.
There is a problem in the schema: the element "job" that you define inside the
complexType rslType is *not* qualified. This is because 1) there is no
elementFormDefault="qualified" attribute on your schema element and 2) there
is no form="qualified" attribute on the element declaration itself, inside
the complex type. Schema spec states that in such a case, the element
declaration is assumed to be for an element that is *not* qualified.
In other words, the following document *would* satisfy your schema (and in
fact does with Xerces 2.2):
<?xml version="1.0" encoding="UTF-8"?>
<!-- This declaration has absolutely no effect, so I've removed it:
xmlns:rsl="http://schemas.gridforum.org/gridServices/rsl";
-->
<rsl xmlns="http://schemas.gridforum.org/gridServices/rsl";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://schemas.gridforum.org/gridServices/rsl
schema/test.xsd">
<job xmlns=""> Bastard! </job>
</rsl>
What you probably want however, is to *qualify* the element declaration in
your schema. There are two ways to do this: 1) using an "elementFormDefault"
attribute on the top-level schema element (which essentially qualifies *all*
local element declarations, except those that explicitly contain a "form"
attribute specifying otherwise) or 2) using a "form" attribute on the element
declaration. This means only that particular element will be qualified.
In both cases, you should set the chosen attribute value to "qualified".
Examples:
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema";
targetNamespace="http://schemas.gridforum.org/gridServices/rsl";
xmlns:rsl="schemas.gridforum.org/gridServices/rsl"
version="0.2"
elementFormDefault="qualified">
...
</xsd:schema>
- or -
(inside complexType "rslType" definition)
...
<xsd:element name="job" form="qualified" type="xsd:string" minOccurs="0"/>
...
Doing this, your original document validates.
The features I needed to set were:
- validation (setValidating(true))
- namespaces (setNamespaceAware(true))
"http://apache.org/xml/features/validation/dynamic"; /* possibly not
needed */
"http://apache.org/xml/features/validation/schema";
I found all these in the Xerces documentation.
I really hope this helps you all solve your problem. It took me a while myself
to understand the elementFormDefault attribute by the way ;)
