JavaScript can be used to extract a specific value from a SOAP response

In order to extract the Patient ID (PATAA000000040) from the SOAP response below using JavaScript and insert it into a Mirth destination, we need to target the value under the livingSubjectId tag. It's important to note that this tag may repeat, but we should only consider the first iteration of livingSubjectId.

How would you implement this in JavaScript?

<?xml version='1.0' encoding='UTF-8'?>
<S:Envelope
    xmlns:S="http://www.w3.org/2003/05/soap-envelope">
    <S:Body>
        <ns3:RespondingGateway_PRPA_IN201306UV02Response
            xmlns="urn:gov:hhs:fha:NwHINc:common:NwHINccommon"
            xmlns:ns2="http://schemas.xmlsoap.org/ws/2004/08/addressing"
            xmlns:ns3="urn:hl7-org:v3"
            xmlns:ns4="urn:gov:hhs:fha:NwHINc:common:patientcorrelationfacade">
           [SOAP Response Continued...]

This is an attempted solution:

msg = new XML(msg);
logger.info(msg);
var soap = new Namespace('http://www.w3.org/2003/05/soap-envelope');
var edeia = new Namespace('http://schemas.xmlsoap.org/ws/2004/08/addressing');
var PatientID = msg.soap::Body.edeia::controlActProcess.edeia::queryByParameter.edeia::livingSubjectId.toString();
logger.info(PatientID);
channelMap.put('PatientID',PatientID);

However, the following error occurred in Mirth:

Transformer error
ERROR MESSAGE: Error evaluating transformer
com.mirth.connect.server.MirthJavascriptTransformerException: 
CHANNEL:    Test SOAP Response
CONNECTOR:  sourceConnector
SCRIPT SOURCE:

Answer №1

It seems like the XML tag is not being parsed correctly, which is causing the error message to appear. When I received a SOAP response, it looked like this.

<S:Envelope xmlns:S="http://test.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENV="http://test.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header/>
<S:Body>
<ns1:addInformation xmlns:ns2="http://Getdatawebservice/">;
<send>
<MrnNumber>MRN5023150</MrnNumber>
<isError>True</isError>
<ErrorReason>Patient deceased</ErrorReason>
</send>
</ns1:addInformation>
</S:Body>
</S:Envelope>

The code snippet below demonstrates how I extracted details from the ErrorReason tag within the response message. This code was written in the Edit Response section of the destination.

//Replace : completely, mirth somehow not takes it
var updateMsg= new XML (msg).toString().replace(/:/g,”)
    //Create a new XML using it
    var newMsg= new XML (updateMsg);
    //Get the specific Error Reason XML tag value
    var checkError = newmsg['SBody']['ns1addInformation ']['send']['isError'].toString();
    // Not required in your scenario
    if(checkError=="false")
    {
    var errorMessage = "Message Sent Successfully";
    channelMap.put("errorMessage", errorMessage);
    }

You can utilize the above code to parse other fields as well. It should be effective. If you encounter multiple occurrences of the field, you'll need to implement looping logic.
