How to Inspect the Contents of a SimpleXMLElement when print_r() Outputs Empty?

SimpleXML and asXML() - Inspecting Its Contents

Encountering an empty output when using print_r() on a SimpleXMLElement can be disconcerting. To effectively explore its contents, it's recommended to employ the asXML() method instead.

In your specific scenario, the print_r() output shows an empty Item node because the XML's Item child includes an attributes node within a different namespace. To access these attributes, you can utilize one of several techniques:

  • $xml->Item->children("http://systinet.com/wsdl/com/osm/webservices/service/");
  • $xml->Item->children('q1', true);
  • $xml->Item->xpath('//q1:Attribute');

Employing asXML() provides a more comprehensive representation of the SimpleXMLElement, allowing thorough inspection of its structure and content.
