Hello all im trying to consume a web service using javascript and soap but i cant seem to figure out how to getthe response,

Any help with this is greatly appreciated im at a loss on it

Here's what the soap response looks like
HTTP/1.1 200 OK
Content-Type: application/soap+xml; charset=utf-8
Content-Length: length

<?xml version="1.0" encoding="utf-8"?>
<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">
  <soap12:Body>
    <hintResponse xmlns="http://microsoft.com/webservices/">
      <hintResult>string</hintResult>
    </hintResponse>
  </soap12:Body>
</soap12:Envelope>


Here's the Code
             <script type="text/javascript" language=javascript>
 
  var xmlHttp;
  var  strEnvelope = "<?xml version='1.0' encoding='utf-8'?>"+
           " <soap12:Envelope xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'" +
      
          " xmlns:xsd='http://www.w3.org/2001/XMLSchema'" +
      
          " xmlns:soap12='http://www.w3.org/2003/05/soap-envelope'>" +
      
          "  <soap12:Body>" +
      
          "    <hint xmlns='http://microsoft.com/webservices'>" +
      
          "    <Term>b</Term></hint>" +
      
          "  </soap12:Body>" +
      
          "</soap12:Envelope>";

function showHint(str)
{
 
if (str.length > 0)
{
var url="http://localhost:3601/WebSite2/hint.asmx/hint";
xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
xmlHttp.open('POST', url , true);
xmlHttp.setRequestHeader("Content-Type","application/soap+xml; charset=utf-8")
xmlHttp.send(strEnvelope);
xmlHttp.onreadystatechange = checkState;
}
}
function checkState(){
  if(xmlHttp.readyState=="complete"||xmlHttp.readyState==4){
   placeHint(xmlHttp.responseXML);
     }
  else{
  alert("Not Complete");
  }
}
 function placeHint(xmlresponse) {
 alert(xmlresponse);
 response  = xmlresponse.documentElement;
  method = response.getElementsByTagName('hint')[0].firstChild.data;
  result = response.getElementsByTagName('Term')[0].firstChild.data;
}
</script>
 
I receive [object] in the alert inside of the placeHint function but then receive the error that response is null or not an object. Im not even sure if this is the best method for getting the data. Like i said id appreciate any insight

I changed to this but still have the same problems
 method = response.getElementsByTagName('hintResponse')[0].firstChild.data;
  result = response.getElementsByTagName('hintResult')[0].firstChild.data;

Here's the latest version im trying to load the response into another object then iterate through it but im getting nowhere i get two alerts that say object and one that says 4 . both appear to create and load but i cant figure out how to access the elements
     <script type="text/javascript" language=javascript>
 
  var xmlHttp;
  var  strEnvelope = "<?xml version='1.0' encoding='utf-8'?>"+
           " <soap:Envelope xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'" +
      
          " xmlns:xsd='http://www.w3.org/2001/XMLSchema'" +
      
          " xmlns:soap='http://www.w3.org/2003/05/soap-envelope'>" +
      
          "  <soap:Body>" +
      
          "    <hint xmlns='http://microsoft.com/webservices'>" +
      
          "    <Term>b</Term></hint>" +
      
          "  </soap:Body>" +
      
          "</soap:Envelope>";

function showHint(str)
{
 
if (str.length > 0)
{
var url="http://localhost:3601/WebSite2/hint.asmx/hint";
xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
xmlHttp.open('POST', url , true);
xmlHttp.setRequestHeader("Content-Type","text/xml; charset=utf-8")
xmlHttp.send(strEnvelope);
xmlHttp.onreadystatechange = checkState;
}
}
function checkState(){
  if(xmlHttp.readyState=="complete"||xmlHttp.readyState==4){
   placeHint(xmlHttp.responseXML);
   
     }
  else{
  alert("Not Complete");
  }
}
 function placeHint(xmlresponse) {
 var response;
 alert(xmlHttp.responseXML);
 oDoc =new ActiveXObject("MSXML2.DOMDocument.4.0")  
 oDoc.async = true;
 oDoc.setProperty("SelectionNamespaces","xmlns:soap='http://www.w3.org/2001/XMLSchema'")
 oDoc.load(xmlresponse)
 alert(oDoc.readyState);
 if(oDoc.readyState == 4 || oDoc.readyState == "complete"){
  result = oDoc.getElementsByTagName('hintResult')
 
  alert(result);
  }  else
  {
  alert("Not Ready")
}
}
</script>

 var resultNode;
 oDoc =new ActiveXObject("MSXML2.DOMDocument.4.0")  
 oDoc.async = false;
 oDoc.load(xmlresponse)
 var sNamespaces = "xmlns:soap='http://www.w3.org/2001/XMLSchema'" + " xmlns:default='http://microsoft.com/webservices/'";
 oDoc.setProperty("SelectionNamespaces",sNamespaces);
 var sXPath="/*/soap:Body/default:hintResponse/default:hintResult";
 resultNode = oDoc.selectSingleNode(sXPath);
 alert(resultNode.text);
}

well... I finished it on my own screw the soap i used a post and screw traversing xml with javascript this is an easy and good way to it using xslt

<script language=javascript type="text/javascript">
//posting data to webservice
function postdata(){
var url="http://localhost:3601/WebSite2/hint.asmx/hint";
xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
xmlHttp.open('POST', url , true);
xmlHttp.setRequestHeader("Content-Type","application/x-www-form-urlencoded");
var sendText=document.getElementById("Term").value
xmlHttp.send("Term="+sendText);
xmlHttp.onreadystatechange = checkState;
 }
 //checking for readiness
function checkState(){
  if(xmlHttp.readyState=="complete"||xmlHttp.readyState==4){
   placeHint2(xmlHttp.responseXML);
   }
}
//adding data to page through transform
function placeHint2(xmlresponse){
// Load XML
var xml = new ActiveXObject("Microsoft.XMLDOM")
xml.async = false
xml.load(xmlresponse)
// Load XSL
var xsl = new ActiveXObject("Microsoft.XMLDOM")
xsl.async = false
xsl.load("hint.xsl")
// Transform
document.getElementById("suggested").innerHTML =  xml.transformNode(xsl);
}
</script>
