I am attempting to validate my XML using XSD in Java by using DOM validator.
Although, manually, I know that the document is indeed valid, DOM validator shouts back at me and says:
cvc-complex-type.3.2.2: Attribute <xsi:schemaLocation> is not allowed to appear in the element <people>
I have made sure that:
setNamespaceAware()
is set to true
The schemaLanguage
property was set before schemaSource
schemaLanguage
is set to http://ww.w3.org/2001/XMLSchema
Both the XSD
and XML
are in the same folder as the .java
and .class
file
import org.xml.sax.*;
import org.xml.sax.helpers.*;
import javax.xml.parsers.*;
public class DOMValidator {
String xmlInstance = null;
String xmlSchema = null;
public static void main(String[] args){
DOMValidator validator = new DOMValidator();
validator.validateXML("student.xsd",
"helloWorld.xml");
}
public void validateXML(String xsd,String xml){
xmlSchema = xsd;
xmlInstance = xml;
beginValidation();
}
public void beginValidation(){
try{
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setNamespaceAware(true);
factory.setValidating(true);
factory.setAttribute("http://java.sun.com/xml/jaxp/properties/schemaLanguage",
"http://www.w3.org/2001/XMLSchema");
factory.setAttribute("http://java.sun.com/xml/jaxp/properties/schemaSource",
xmlSchema);
ErrorHandler errorHandler = new ErrorHandler();
DocumentBuilder builder = factory.newDocumentBuilder();
builder.setErrorHandler(errorHandler);
builder.parse(xmlInstance);
if(errorHandler.errorOccured == true){
System.out.println("Document is Invalid.");
System.out.println(errorHandler.ex.getMessage());
}else{
System.out.println("Doument is valid");
}
}catch(ParserConfigurationException e){
e.printStackTrace();
}catch(SAXException e){
e.printStackTrace();
}catch(Exception e){
e.printStackTrace();
}
}
private class ErrorHandler extends DefaultHandler{
public SAXParseException ex = null;
public boolean errorOccured = false;
@Override public void error(SAXParseException ex){
this.ex = ex;
errorOccured = true;
}
@Override public void fatalError(SAXParseException ex){
this.ex = ex;
errorOccured = true;
}
@Override public void warning(SAXParseException ex){
this.ex = ex;
errorOccured = true;
}
}
}
<xs:schema xmlns:xs="http://www.w3c.org/2001/XMLSchema"
xmlns="http://www.cmu.edu/ns/blank"
targetNamespace="http://www.cmu.edu/ns/blank"
elementFormDefault="qualified">
<people

xmlns:xsi="http://www.w3c.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.cmu.edu/ns/blank student.xsd">
How do I resolve this?
The problem is here:
<xs:schema xmlns:xs="http://www.w3c.org/2001/XMLSchema" .....>
and
<people
xmlns="http://www.cmu.edu/ns/blank"
xmlns:xsi="http://www.w3c.org/2001/XMLSchema-instance"....>
The problem is the c in the w3c.org
. DOM parser expects it to be w3.org
everywhere-- in the XML document, in the XML Schema Document, in the schemaLanguage
and the schemaSource
properties.
