Thanks Michael for your explanations.
I have tried to add your remarks to my code,
without success
I am using JDK 1.4.2_13 with xerces 2.9.0
-------------------------------------------------------------
Here is the code:
element.setAttribute("xmlns",
"http://example.com/zedv/services/Logger/log";);
element.setAttribute("xmlns:xsi",
XMLConstants.W3C_XML_SCHEMA_INSTANCE_NS_URI);
DocumentBuilderFactory newInstance = DocumentBuilderFactory.
newInstance();
newInstance.setNamespaceAware(true);
Document doc2Validate = newInstance.newDocumentBuilder().newDocument();
Element importNode = (Element) doc2Validate.importNode(element, true);
doc2Validate.appendChild(importNode);
doc2Validate.normalize();
Schema schema = SchemaFactory.newInstance(
XMLConstants.W3C_XML_SCHEMA_NS_URI).newSchema(
new StreamSource(this.getClass().
getResourceAsStream("/LoggerLog.xsd")));
Validator newValidator = schema.newValidator();
newValidator.setErrorHandler(new ValidationErrorHandler());
newValidator.validate(new DOMSource(doc2Validate));
-------------------------------------------------------------
The XSD looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";
xmlns="http://example.com/zedv/services/Logger/log";
targetNamespace="http://example.com/zedv/services/Logger/log";
elementFormDefault="qualified">
<xs:element name="log" type="log"/>
<xs:complexType name="log">
<xs:attribute name="info" type="xs:string"/>
</xs:complexType>
</xs:schema>
-------------------------------------------------------------
The XML is here:
<?xml version="1.0" encoding="UTF-8" ?>
<log info="starting test"/>
-------------------------------------------------------------
I have added xerces 2.9.0 to the classpath an have run
the code above with jdk 1.4.3_13
The result was this exception
org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the declaration
of element 'log'.

Exception in thread "main"
Then I changed the jdk to 1.5_6 and the same code is working fine....
Do you have any idea?
