Function to convert XML to JSON

xmlToJson.js

// Changes XML to JSON
// Modified version from here: http://davidwalsh.name/convert-xml-json
xmlToJson(xml) {
  // Create the return object
  let obj = {};

  if (xml.nodeType === 1) { // element
    // do attributes
    if (xml.attributes.length > 0) {
      obj['@attributes'] = {};
      for (let j = 0; j < xml.attributes.length; j += 1) {
        const attribute = xml.attributes.item(j);
        obj['@attributes'][attribute.nodeName] = attribute.nodeValue;
      }
    }
  } else if (xml.nodeType === 3) { // text
    obj = xml.nodeValue;
  }

  // do children
  // If just one text node inside
  if (xml.hasChildNodes() && xml.childNodes.length === 1 && xml.childNodes[0].nodeType === 3) {
    obj = xml.childNodes[0].nodeValue;
  } else if (xml.hasChildNodes()) {
    for (let i = 0; i < xml.childNodes.length; i += 1) {
      const item = xml.childNodes.item(i);
      const nodeName = item.nodeName;
      if (typeof (obj[nodeName]) === 'undefined') {
        obj[nodeName] = xmlToJson(item);
      } else {
        if (typeof (obj[nodeName].push) === 'undefined') {
          const old = obj[nodeName];
          obj[nodeName] = [];
          obj[nodeName].push(old);
        }
        obj[nodeName].push(xmlToJson(item));
      }
    }
  }
  return obj;
},

Great News! I finally solved my own problem. Everything is working now. I had to include another child node to be retrieved (CDATA-Section) of type level 4 and bingo, all data needed came in and I can now extract what I need in the format I need it. Thanks all.

Another version:

// xml is the result of `DOMParser.parseFromString()`
function xml2json(xml) {
  if (xml.children.length === 0)
    return xml.textContent.trim()

  const obj = {}

  for (let child of xml.children) {
    const name = child.nodeName
    if (obj[name] === undefined)
      obj[name] = xml2json(child)
    else {
      if (!Array.isArray(obj[name]))
        obj[name] = [obj[name]]
      obj[name].push(xml2json(child))
    }
  }

  return obj
}

Great.Thanks much
