</SOAP-ENV:Envelope>
i have try to get web_status nodes but everything fails
Try 1
$dom = new DOMDocument();
$dom->load($xml_response);
$web_status = $dom->getElementsByTagName('web_status');
Try 2
$dom = new DOMDocument();
$dom->load($xml_response);
$xpath = new DOMXPath($dom);
$xpath->registerNamespace("ns0", "/PELTT01");
$web_status = $xpath->query('//ns0:web_status');
Can anyone help me parse this soap response
Any help appreciated

Answer 1

If I understand you correctly, you're looking for something close to your Try 2:
$dom->loadXML($xml_response);#note: NOT just "load"
$xpath = new DOMXPath($dom);
$xpath->registerNamespace("ns0", "/PELTT01");
$web_status = $xpath->query('//ns0:web_status');
foreach ($web_status as $wb)
{
$cn = $wb->childNodes;
foreach ($cn as $c){
echo trim($c->textContent);
}
}
Output:
date1
time1
station1
title1
date2
time2
station2
title2
