QXmlSchema Class Reference
[QtXmlPatterns module]

bool QXmlSchema::load ( const QUrl & source )

Sets this QXmlSchema to a schema loaded from the source URI.

If the schema is invalid, false is returned and the behavior is undefined.

Example:

     QUrl url("http://www.schema-example.org/myschema.xsd");

     QXmlSchema schema;
     if (schema.load(url) == true)
         qDebug() << "schema is valid";
     else
         qDebug() << "schema is invalid";

See also isValid().

bool QXmlSchema::load ( QIODevice * source, const QUrl & documentUri = QUrl() )

Sets this QXmlSchema to a schema read from the source device. The device must have been opened with at least QIODevice::ReadOnly.

documentUri represents the schema obtained from the source device. It is the base URI of the schema, that is used internally to resolve relative URIs that appear in the schema, and for message reporting.

If source is null or not readable, or if documentUri is not a valid URI, behavior is undefined.

If the schema is invalid, false is returned and the behavior is undefined.

Example:

     QFile file("myschema.xsd");
     file.open(QIODevice::ReadOnly);

     QXmlSchema schema;
     schema.load(&file, QUrl::fromLocalFile(file.fileName()));

     if (schema.isValid())
         qDebug() << "schema is valid";
     else
         qDebug() << "schema is invalid";

See also isValid().

bool QXmlSchema::load ( const QByteArray & data, const QUrl & documentUri = QUrl() )

Sets this QXmlSchema to a schema read from the data

documentUri represents the schema obtained from the data. It is the base URI of the schema, that is used internally to resolve relative URIs that appear in the schema, and for message reporting.

If documentUri is not a valid URI, behavior is undefined.

If the schema is invalid, false is returned and the behavior is undefined.

Example:

     QByteArray data( "<?xml version=\"1.0\" encoding=\"UTF-8\"?>"
                      "<xsd:schema"
                      "        xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\""
                      "        xmlns=\"http://qt.nokia.com/xmlschematest\""
                      "        targetNamespace=\"http://qt.nokia.com/xmlschematest\""
                      "        version=\"1.0\""
                      "        elementFormDefault=\"qualified\">"
                      "</xsd:schema>" );

     QBuffer buffer(&data);
     buffer.open(QIODevice::ReadOnly);

     QXmlSchema schema;
     schema.load(&buffer);

     if (schema.isValid())
         qDebug() << "schema is valid";
     else
         qDebug() << "schema is invalid";
