QXmlSchemaValidator Class

Detailed Description

The QXmlSchemaValidator class loads, parses an XML instance document and validates it against a W3C XML Schema that has been compiled with QXmlSchema.

The following example shows how to load a XML Schema from a local file, check whether it is a valid schema document and use it for validation of an XML instance document:

     QUrl schemaUrl("file:///home/user/schema.xsd");

     QXmlSchema schema;
     schema.load(schemaUrl);

     if (schema.isValid()) {
         QFile file("test.xml");
         file.open(QIODevice::ReadOnly);

         QXmlSchemaValidator validator(schema);
         if (validator.validate(&file, QUrl::fromLocalFile(file.fileName())))
             qDebug() << "instance document is valid";
         else
             qDebug() << "instance document is invalid";
     }
