    Make sure to load your data prior to calling ->setRelaxNGSchema() otherwise you will get an error.

    <?php
    $xml_reader     = new XMLReader();
    $xml_reader->setRelaxNGSchema($rng_schema);
    $xml_reader->xml($xml_data);
    ?>
    Above code generates the following warning: "Warning: XMLReader::setRelaxNGSchemaSource()
    [xmlreader.setrelaxngschemasource]: Unable to set schema. This must be
    set prior to reading or schema contains errors."

    whereas the following does not generate a warning:
    <?php
    $xml_reader     = new XMLReader();
    $xml_reader->xml($xml_data); // or $xml_reader->xml($xml_file);
    $xml_reader->setRelaxNGSchema($rng_schema);
    ?>
