I'm using Javascript to call a SOAP webservice. Using firebug, I can see that the request is successful, and I see the XML SOAP response.
How can I display the response on the webpage? Or even better - how can I display a single node within the XML SOAP response? I thought maybe I can use XPath - but it doesn't seem to be working.
Here is my code:
<html>
<head>
<title>SOAP Client Test</title>
<script type="text/javascript">
function soap() {
var xmlhttp = new XMLHttpRequest();
xmlhttp.open('POST', 'https://mysoapurl.com', true);
// build SOAP request
var sr =
'<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">' +
'<s:Header> ' +
'<USERNAME xmlns="http://www.tempuri.org">MyUsername</USERNAME>' +
'<PASSWORD xmlns="http://www.tempuri.org">MyPassword</PASSWORD>' +
'</s:Header>' +
'<s:Body>' +
'<GetData>Foo</GetData>' +
'</s:Body>' +
'</s:Envelope>';
// Send the POST request
xmlhttp.setRequestHeader('Content-Type', 'text/xml');
xmlhttp.setRequestHeader('SOAPAction', 'http://tempuri.org/MySoapActionURL');
xmlhttp.send(sr);
// send request
// ...
// This XPath query should get us the <GetResponse> element from the SOAP XML Response
var query = "//ns1:GetResponse[1]";
// This object defines the namespaces used in the query
var namespaceMapping = {
ns1: "http://tempuri.org/", // SOAP namespace
diffgr: "urn:schemas-microsoft-com" // the service-specific namespace
};
// Extract the <GetResponse> element from the response document
var responseNode=XML.getNode(XMLHttpRequest.responseXML, query, namespaceMapping);
return responseNode;
}
window.onload = soap;
</script>
</head>
<body>
</body>
<html>
Any help is greatly appreciated. Thanks for looking.
You can use the evaluate
method on the responseXML
:
var xmlhttp = new XMLHttpRequest();
xmlhttp.open('POST', 'https://mysoapurl.com', true);
// build SOAP request
var sr =
'<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">' +
'<s:Header> ' +
'<USERNAME xmlns="http://www.tempuri.org">MyUsername</USERNAME>' +
'<PASSWORD xmlns="http://www.tempuri.org">MyPassword</PASSWORD>' +
'</s:Header>' +
'<s:Body>' +
'<GetData>Foo</GetData>' +
'</s:Body>' +
'</s:Envelope>';
// Send the POST request
xmlhttp.setRequestHeader('Content-Type', 'text/xml');
xmlhttp.setRequestHeader('SOAPAction', 'http://tempuri.org/MySoapActionURL');
xmlhttp.onload = function(evt) {
var doc = this.responseXML;
var namespaceMapping = {
ns1: "http://tempuri.org/",
diffgr: "urn:schemas-microsoft-com"
};
var node = doc.evaluate('//ns1:GetResponse[1]', doc,
function (prefix) {
return namespaceMapping[prefix];
},
XPathResult.FIRST_ORDERED_NODE_TYPE,
null).singleNodeValue;
if (node != null) {
// now access node.textContent respectively run further queries on node
}
};
xmlhttp.send(sr);
