sourceString containing the RelaxNG Schema.
Returns TRUE on success or FALSE on failure.
If you get the following warning message when calling ->setRelaxNGSchemaSource(): "Warning: XMLReader::setRelaxNGSchemaSource()
[xmlreader.setrelaxngschemasource]: Unable to set schema. This must be
set prior to reading or schema contains errors."
Make sure to load data using XMLReader::open() or XMLReader::xml() prior to calling XMLReader::setRelaxNGSchemaSource().
Cf. comment on XMLReader::setRelaxNGSchema for more details.
This function and setRelaxNGSchema() seem picky about when they are called - right after the call to open(). For example:
<?php
$schema="/path/to/schema.rng";
$xmlfile="/path/to/xml.xml";
$xml = new XMLReader();
$xml->open($xmlfile);
$xml->setRelaxNGSchemaSource(file_get_contents($schema));
while ($xml->read()) {
// ...
}
$xml->close();
?>
