Question

I have an xml.
I have created one XSD for the xml.

I want to write a prog to validate the xml against xsd.
I wrote a prog and got individual values am setting.

But is there a way, i can give the xml file as input and could see if the xml is valid against the XSD?

Thanks,
Nini

This is an example of xml validation with XSD.

public static boolean validate() {
    Source xmlFile = null;
    File schemaFile;
    SchemaFactory schemaFactory;
    Schema schema;
    try {
        schemaFile = new File(xsdFileName);
        xmlFile = new StreamSource(new File(xmlFileName));
        schemaFactory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
        schema = schemaFactory.newSchema(schemaFile);
        Validator validator = schema.newValidator();
        validator.validate(xmlFile);
        System.out.println(xmlFile.getSystemId() + " is valid");
    } catch (SAXException | IOException e) {
        System.out.println(xmlFile.getSystemId() + " is NOT valid");
        System.out.println("Reason: " + e.getLocalizedMessage());
        return false;
    }
    return true;
}
