SimpleXRD is an extraordinarily simple parser for XRD documents written in PHP 5.

This XRD parser supports all the features of XRD which can be translated into its JSON representation under RFC 6415. This means that the parser does not support extensibility under the XRD specification.

Using the parser is straightforward. Assuming the XRD code has been loaded into a variable called $xml. Then the code is simply

$parser = new SimpleXRD();
$parser->load($xml);
$jrd = $parser->parse();
$parser->free();

The JSON representation can then be obtained by using json_encode($jrd).
