how to properly get data from an XML SOAP response in PHP?

Question

I'm able to access part of the XML record but the problem is the returned value is presented in this format below:

SimpleXMLElement Object
(
    [0] => 
1234567
)

And if I use inspect element this is what it shows:

<xx>
   <yy>
      <a>1</a>
      <b>2</b>
      <c>3</c>
      <d>4</d>
   </yy>
   <zz Type="type">
      <e>5</e>
      <f>6</f>
      <g>
         <h>7</h>
      </g>
   </zz>
</xx>

SOAP XML Response: (The actual SOAP response have < and > converted to < and > I just changed it here to make it more readable)

<s:envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:body>
<processrequestresponse xmlns="http://zzz.org/">
<processrequestresult>
<xx>
   <yy>
      <a>1</a>
      <b>2</b>
      <c>3</c>
      <d>4</d>
   </yy>
   <zz Type="type">
      <e>5</e>
      <f>6</f>
      <g>
         <h>7</h>
      </g>
   </zz>
</xx>
</processrequestresult>
</processrequestresponse>
</s:body>
</s:envelope>

Code:

$xml = simplexml_load_string($response);
$data    = $xml->xpath("//s:Body/*")[0];
        $details = $data->children("http://zzz.org/");
        $test    = $details->ProcessRequestResult[0];
        echo '<pre>';
        print_r($test);

So my question is how do I access the values for a,b,c,d,e,f, and g individually?

Answer 1

Try it this way:

$data = $xml->xpath('//*//text()');

foreach ($data as $datum) {
    if (strlen(trim($datum))>0)
    echo trim($datum)."

";
}

Output should be 1 through 7.
