parse json in nodejs with : in the json keys - node.js

Question

My nodejs code receives a response from a HTTP POST call which is in xml. I convert it to json using xml2js, and now I need to read this so as to get the data of one of the json keys.
This is how a part of my json data looks. I am trying to read this as follows:
var base64encoded = jsonxml."soapenv:Body".runReportResponse.runReportReturn.reportBytes;
However, when I run this i get the error message:
jsonxml."soapenv:Body".runReportResponse.runReportReturn.reportBytes;
^^^^^^^^^^^^^^
SyntaxError: Unexpected string.'
I have also tried by removing the double quotes, but then it gives exception to the colon (:) which appears in the data. How do I read such kind of data?
Entire json:
[

"Envelope": {
"$": {
"xmlns:soapenv": "http://schemas.xmlsoap.org/soap/envelope/",
"xmlns:xsd": "http://www.w3.org/2001/XMLSchema",

I've updated the answer base on your new JSON (thank you!). It looks like the problem is maybe that each property in the JSON is really an array.
I'd suggest if you don't want this behaviour, to have a look at the explicitArray options in the xml2js options object setting it to false.
e.g. :
explicitArray (default: true): Always put child nodes in an array if true; otherwise an array is created only if there is more than one.
This might simplify accessing properties!
let response = [
{
"Envelope": {
"$": {
"xmlns:soapenv": "http://schemas.xmlsoap.org/soap/envelope/",
"xmlns:xsd": "http://www.w3.org/2001/XMLSchema",
"xmlns:xsi": "http://www.w3.org/2001/XMLSchema-instance"
},

"runReportResponse": {

"runReportReturn": {
"metaDataList": {

console.log("Report bytes: ", response[0].Envelope.Body.runReportResponse.runReportReturn.reportBytes);
