How to getelementbytagname from specific asp.net web service

Question

Please, I'm stuck in a little problem using getElementsByTagName command on a js file with a PhoneGap project. I'm consuming a asp.net web service that works perfectly, but I failed to get the result that the web service is returning me, and that is string from <IngresarRegistroMovilResult> tag.

This is my function that receives the web service return:

function processResult() {
    if (xmlhttp.readyState==4 && xmlhttp.status==200) {
        var theXML = xmlhttp.responseXML.documentElement;
        var resultadoWebService = theXML.getElementsByTagName('string')[0].firstChild.nodeValue;

        var output = "Resultado: ";
        output += resultadoWebService;

        console.log("Pasamos por processResult, con var output:"+output);

        document.getElementById("resultadows").innerHTML = output;

    }
};

This is the specification of the web service:

POST /servicio.asmx HTTP/1.1
Host: dondeestamifamilia.masterdevelopment.co
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>
    <IngresarRegistroMovil xmlns="http://dondeestamifamilia.masterdevelopment.co/">
      <hashString>string</hashString>
    </IngresarRegistroMovil>
  </soap12:Body>
</soap12:Envelope>

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>
    <IngresarRegistroMovilResponse xmlns="http://dondeestamifamilia.masterdevelopment.co/">
      <IngresarRegistroMovilResult>string</IngresarRegistroMovilResult>
    </IngresarRegistroMovilResponse>
  </soap12:Body>
</soap12:Envelope>

This is the fragment corresponding to IngresarRegistroMovil method, from the wsdl:

<s:element name="IngresarRegistroMovil">
    <s:complexType>
        <s:sequence>
            <s:element minOccurs="0" maxOccurs="1" name="hashString" type="s:string"/>
        </s:sequence>
    </s:complexType>
</s:element>
<s:element name="IngresarRegistroMovilResponse">
    <s:complexType>
        <s:sequence>
            <s:element minOccurs="0" maxOccurs="1" name="IngresarRegistroMovilResult" type="s:string"/>
        </s:sequence>
    </s:complexType>
</s:element>

I've tried theXML.getElementsByTagName('string')[0].firstChild.nodeValue; but I get: Uncaught TypeError: Cannot read property 'firstChild' of undefined. theXML.getElementsByTagName('string')[0]; but I get: undefined. theXML.getElementsByTagName('string')[0].nodeValue; but I get: Uncaught TypeError: Cannot read property 'nodeValue' of undefined.

Please, your great support will be extremely valuable to me.

Thanks.

The tagname is IngresarRegistroMovilResult not string which you can acces by theXML.getElementsByTagName('IngresarRegistroMovilResult')[0].textContent (if I made no typo)
