Answer 1

Yes, all DOM API functions works good in the XML, but i recommend you to look towards this approach. To use this syntax you should use xmldom and xpath libraries;

Answer 2

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))
