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();

?>
