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);

?>
