Took me a while to get a working example.  Here it is:



<?php



# enable warnings

ini_set( 'track_errors', 1);

ini_set('error_reporting', E_ALL | E_STRICT);



# this is a sample relaxNG definition

$rng = <<<EOT

<?xml version="1.0" encoding="UTF-8"?>

<grammar ns="" xmlns="http://relaxng.org/ns/structure/1.0"

  datatypeLibrary="http://www.w3.org/2001/XMLSchema-datatypes">

  <start>

    <element name="apple">

      <element name="pear">

        <data type="NCName"/>

      </element>

    </element>

  </start>

</grammar>

EOT;



# well formed xml, but invalid per schema

# too many pears

$bad_xml =<<<EOT

<?xml version="1.0"?>

<apple>

  <pear>Pear</pear>

  <pear>Pear</pear>

</apple>

EOT;



# well formed xml and valid per schema

$good_xml =<<<EOT

<?xml version="1.0"?>

<apple>

  <pear>Pear</pear>

</apple>

EOT;



# this function does the work, it tests the relaxNG in the string $rng

# against the xml in string $xml

Function relaxNG ( $xml, $rng ) {

        $dom_xml = new DomDocument;

        $dom_xml->loadXML($xml);

                        

        if ( $dom_xml->relaxNGValidateSource ( $rng ) ) {

                echo "Good\n";

        } else {

                echo $php_errormsg . "\n";

        }

}       



# test the good xml, will echo:

#    Good

relaxNG ($good_xml, $rng);

                        

# test the bad xml, will echo:

#    Did not expect element pear there

relaxNG ($bad_xml, $rng);



?>



results:



Good

Did not expect element pear there
