'Attribute not allowed to appear in element' error

[matt hegarty]

Hi
I am relatively new to XML, but am having problems with a validation
issue.

When the XML is parsed and validated using Xerces, the following error
is seen:

cvc-complex-type.3.2.2: Attribute 'xsi:noNamespac eSchemaLocation ' is
not allowed to appear in element 'questionFeed'.

This error does not appear when the file is validated against the
schema using the XMLSpy tool. The file passes validation when the
'noNamespaceSch emaLocation' entry in the XML is removed. So I guess
the question is: how can I structure my schema so that this error is
not seen? Incidentally, the 'noNamespaceSch emaLocation' is
irrelevant in the XML - I validate programmaticall y.

Snippets of both schema and XML are attached:

== SCHEMA FILE ===

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
elementFormDefa ult="qualified" attributeFormDe fault="unqualif ied">

<xs:element name="questionF eed">
<!-- snipped -->
</xs:element>
</xs:schema>
== XML FILE ===

Maybe Xerces complains as you have elementFormDefa ult="qualified" , try with
elementFormDefa ult="unqualifie d"
which seems to be what you want anyway as you do not use a target
namespace and your XML instance doesn't have a namespace on the elements.

Make sure you turn namespaces support of your parser on. If you
obtain your parser instance through JAXP you should call
setNamespaceAwa re(true) on the parser factory instance.

Thanks for the responses.
I followed Stanimir's suggestion and this seems to have solved the
problem.

Alternatively (I haven't tested it though), if you're going to
validate documents which elements doesn't have namespace, using such
XML Schema that doesn't specify 'targetNamespac e', you could not
include the 'noNamespaceSch emaLocation' attribute and set the schema
location through the parser factory properties:

"Properties for enabling schema validation" in the JAXP 1.2
specification <http://java.sun.com/xml/downloads/jaxp.html>.

You could get immediate online information from:
