How to log API responses to Console and save to a data file using pm.sendRequest

问题

I am fairly new to Postman.

I am trying to generate a file using an XML API and log data to Postman Console while looping through different request parameters ([DateOut] in my case). The file I am trying to generate should look like this:

---

DateOut | PickupLocationCode | ItemType | Status

10/19/2018 | YVR | A100 | Available
10/20/2018 | YYC | A200 | On Request

---

I found out how to loop through the data file and get valid responses (in Postman Runner under Response Body). My data loop file (CSV) looks like this:

DateOut | PickupLocationCode

10/19/2018 | YVR

10/20/2018 | YYC

---

My API request looks like this:

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <soap:Body>
        <GetItemTypeStatus xmlns="http://someurl.org/">
            <Credentials>
                <Agent>the_username</Agent>
                <Password>the_password</Password>
            </Credentials>
            <Data>
                <PickupLocationCode>{{PickupLocationCode}}</PickupLocationCode>
                <DateOut>{{DateOut}}</DateOut>
            </Data>
        </GetItemTypeStatus>
    </soap:Body>
</soap:Envelope>

---

Here is my API response:

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <soap:Body>
        <GetItemTypeStatusResponse xmlns="http://tempuri.org/">
            <GetItemTypeStatusResult>
                <StatusInfo>
                    <Success>succeeded</Success>
                    <Remarks>Available</Remarks>
                </StatusInfo>
                <ItemsStatus>
                    <ItemStatus>
                        <PickupLocationCode>YVR</PickupLocationCode>
                        <ItemTypeID>109</ItemTypeID>
                        <ItemType>A100</ItemType>
                        <Status>Available</Status>
                    </ItemStatus>                  
                </ItemsStatus>
            </GetItemTypeStatusResult>
        </GetItemTypeStatusResponse>
    </soap:Body>
</soap:Envelope>

Before logging values to console I set the following variables under Pre-request Script:

pm.environment.set("DateOut", "01/01/2018");
pm.environment.set("PickupLocationCode", "YVR");

---

I am using the test below in Postman to log the values to Console. Source: Extract a value from XML response and set it as a global variable in Postman

// Convert XML output to JSON format
var jsonObject = xml2Json(responseBody);

//Add Departure Date
let departuredate = pm.iterationData.get("DateOut");
//console.log("Departure Date: ", departuredate);

// Take care of Envelope and Body tags, grab data and add DateOut
var activeStatus = jsonObject['soap:Envelope']['soap:Body'].GetItemTypeStatusResponse.GetItemTypeStatusResult.ItemStatus.ItemStatus.concat(departuredate);

// Assigning the extracted value in to a global variable
pm.globals.set ("availability", JSON.stringify(activeStatus));
console.log(['Status '] + pm.globals.get("availability"));

Here is the script that writes the API response to the file. A local server is needed to do this but the set up was very easy. Source: https://documenter.getpostman.com/view/3407886/RWgp1fB5

 let dataToFile = {
        requestName: request.name || request.url,
        fileExtension: 'xml',
        responseData: pm.response.text()
    };

    pm.sendRequest({
        url: 'http://localhost:3000/write',
        method: 'POST',
        header: 'Content-Type:application/json',
        body: {
            mode: 'raw',
            raw: JSON.stringify(dataToFile)
        }
    }, function(err, res) {
        console.log(res);
    });

What I have not found out yet is how to write only the values in the tags to the file rather than the entire API response. I would appreciate any help with this.

Thank you very much.
