<?xml version="1.0" encoding="utf-8"?>
<epp xmlns="urn:ietf:params:xml:ns:epp-1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="urn:ietf:params:xml:ns:epp-1.0 epp-1.0.xsd">
 <response>
  <result code="1000">
   <msg>Command completed successfully</msg>
  </result>
  <resData>
   <domain:chkData xmlns:domain="urn:ietf:params:xml:ns:domain-1.0" xsi:schemaLocation="urn:ietf:params:xml:ns:domain-1.0 domain-1.0.xsd">
    <domain:cd>

XML;
$x = simplexml_load_string($xml);
echo intval($x->response->result["code"]), "\n";
echo strval($x->response->result->msg), "\n";
$ns = $x->response->resData->getNamespaces(true);
$cds = $x->response->resData->children($ns["domain"])->chkData->cd;
foreach ($cds as $key => $value) {
  echo intval($value->name->attributes()["avail"]), strval($value->name), strval($value->reason), "\n";
