Got a "neglected" alert on this question.  Where does the raw data come from?  A good test data set is the first thing we need in order to show you how to assemble this XML document.  Thanks.

To generate SimpleXMLElement object from xml data, you simply pass it to the class constructor:
$xmlStr = ''; // Your xml string will be here
$xml = SimpleXMLElement($xmlStr);

Open in new window


So in your case, you can do something like the following:
$xmlStr = '<?xml version="1.0"?>
  <itwresponse version="1.0">
    <field name="code">
      <string>OK</string>
    </field>
    <field name="output">
      <array>
        <object>
          <field name="ent">
            <string>Text</string>
          </field>
          <field name="expires">
            <string>232432432432423</string>
          </field>
        </object>
      </array>
    </field>
  </itwresponse>';

$xml = new SimpleXMLElement($xmlStr);

Open in new window

If you're new to PHP and want to learn, this article can help you get started with a good foundation.

If you already have this XML document (from whatever source) and want to find information inside it (called "parsing the XML"), this code example should help you get started.  If you have some information you want to put into an XML document, then we need to see the test data set in order to show you some ways of assembling the XML document.  

In any case, the XML tag names, as shown in the original post, are likely to be confusing.  You apparently have field name  tags nested inside field name  tags -- this is not a very strong semantic design!  So if this XML document is one you are producing to send to another application, you might want to refine the meaning and clarify the names of your information elements.

If you're not "stuck" with XML, JSON is almost always a better alternative.

ini_set('display_errors', TRUE);
error_reporting(E_ALL);
echo '<pre>';


// TEST DATA FROM THE POST AT E-E
$xml = <<<EOX
<?xml version="1.0"?>
  <itwresponse version="1.0">
    <field name="code">
      <string>OK</string>
    </field>
    <field name="output">
      <array>
        <object>
          <field name="ent">
            <string>Text</string>
          </field>
          <field name="expires">
            <string>232432432432423</string>
          </field>
        </object>
      </array>
    </field>
  </itwresponse>
EOX;


// MAKE AN OBJECT AND FIND INFORMATION INSIDE THE OBJECT
$obj  = SimpleXML_Load_String($xml, 'SimpleXMLElement', LIBXML_NOCDATA);

$code = (string)$obj->field[0]->string;
var_dump($code);

$expr = (string)$obj->field[1]->array->object->field[1]->string;
var_dump($expr);

Open in new window

Outputs:
string(2) "OK"
string(15) "232432432432423"

Open in new window
