how to read string from xml response body in javascript

Question

i am trying to read the token value from xml response body in javascript variable so far i tried

if (response.getStatusCode() != 200) {
api.fail("HTTP error: " + response.getStatusCode()); }
var xmlDoc = xml.responseXML;
var x = xmlDoc.getElementsByTagName('string');

xml response ENTC~OTKtfKDRu7DIOj0buMfv+PdYDC62yS5GdRHeMO8H+/9UaUs8b2rpN67ONWO3XMkI96zV7x3jVQbeJNovp9Mhh4FbqXsqH2YB/MO/i8y7gJp2GG0QxczIC2oSosSSCAWK

What is not working? Do you get an error? From the code you posted you are never declaring xmlDoc. Maybe var x = xmlDoc.getElementsByTagName('string'); should be var x = xmlresponseBody.getElementsByTagName('string');? — Johan, Apr 29 '20 at 08:05

To read in JS, you need to use DOMParser API. Following is an example:

const text = "<string>This is my xml</string>"; //API response in XML
const parser = new DOMParser();
const xmlDOM = parser.parseFromString(text,"text/xml");
const value = xmlDOM.getElementsByTagName("string")[0].childNodes[0].nodeValue;
console.log(value)

Edit: Example using fetch() API

fetch('Your_API_URL')
.then(response=>response.text())
.then(data=>{
    const parser = new DOMParser();
    const xmlDOM = parser.parseFromString(data,"text/xml");
    const value = xmlDOM.getElementsByTagName("string")[0].childNodes[0].nodeValue;
    console.log(value)
})
.catch(err=>console.log(err))

how do i read xml response in code, i want read first node value – Nikhil Patil Apr 29 '20 at 08:15
I suppose you are already reading in your code. var xmlDoc = xml.responseXML;; //same as 'text' variable in code above. – Pramod Mali Apr 29 '20 at 08:17
i am making a Http GET request which is giving me a xml response – Nikhil Patil Apr 29 '20 at 08:18
Once you get the response from your HTTP GET. Post successful callback/promise/async-await, string can be extracted from the response. – Pramod Mali Apr 29 '20 at 08:21
can you help me with that @Pramod Mali? – Nikhil Patil Apr 29 '20 at 08:22
i want read the response and extract the token string and store it in a variable to later use – Nikhil Patil Apr 29 '20 at 08:27
@NikhilPatil, I have updated my answer with example showing how to call API and use its XML response. – Pramod Mali Apr 29 '20 at 08:47
