XML Schema - validation problem

[Cirip Tomas <to...@theimo.com>]

Hi folks,

I have a problem with validation using XML schema. The error message I am
getting:

[Error] cvc-elt.1: Cannot find the declaration of element 'my:family'.

and I don't understand why?! XML Spy validates XML document just fine. Both
files - family.xsd and family.xml are in the same directory. Thank you

Tomas

Java code:

      DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();

      dbf.setAttribute("http://xml.org/sax/features/validation",
Boolean.TRUE);
      dbf.setAttribute("http://apache.org/xml/features/validation/schema",
Boolean.TRUE);
 
dbf.setAttribute("http://apache.org/xml/features/validation/schema-full-chec
king", Boolean.TRUE);
      dbf.setAttribute("http://xml.org/sax/features/namespaces",
Boolean.TRUE);
 
dbf.setAttribute("http://apache.org/xml/features/continue-after-fatal-error"
, Boolean.TRUE);

      DocumentBuilder parser = dbf.newDocumentBuilder();
      Document document = parser.parse("d:\\temp\\family.xml");

   ...	

XML file:

	<?xml version="1.0" encoding="UTF-8"?>
	<my:family xmlns:my="http://www.my.com"
xmlns:xsi="http://www.w3.org/2000/10/XMLSchema-instance" 
	xsi:schemaLocation="http://www.my.com family.xsd">
		<my:father>John Smith</my:father>
		<my:mother>Jane Doe</my:mother>
	</my:family>

Schema file(family.xsd):

	<?xml version="1.0" encoding="UTF-8"?>
	<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://www.my.com" 
	xmlns="http://www.my.com" elementFormDefault="qualified">
		<xs:element name="family">
			<xs:annotation>
				<xs:documentation>Comment describing your
root element</xs:documentation>
			</xs:annotation>
			<xs:complexType>
				<xs:sequence>
					<xs:element name="father"/>
					<xs:element name="mother"/>
				</xs:sequence>
			</xs:complexType>
		</xs:element>
	</xs:schema>

Xerces support XML Schema Rec, however you are using the Candidate Rec
namespace for XML Schemas: 
> xmlns:xsi="http://www.w3.org/2000/10/XMLSchema-instance"

Per XML Schema Rec [1] the namespaces are:
"http://www.w3.org/2001/XMLSchema"
"http://www.w3.org/2001/XMLSchema-instance"
