I'm a bit confused by the documentation and am willing to create a PR to improve it once I have a better understanding of the following. In https://github.com/bobby-brennan/rss-parser#xml2js-passthrough states that you can pass options to xml2js parser. I have the following:

const parser = new Parser({
 xml2js: {
 stripPrefix: "xmlns:event"
 },
});

I would like to make use of stripPrefix of the xml2js library. It still a bit confusing to me how to use xml2js from the documentation. This new xml2js.Parser() as shown in the docs won't work. What I am tryin to accomplish is to get the namespace fields.

However, when I try to console.log each item from the following function:

const convertRssIntoJson = rssFeed => {
 return new Promise((res, rej) => {
 parser.parseURL(rssFeed, (err, rss) => {
 if (err) {
 return rej(err);
 }
 // console.log(rss.stripPrefix()) is this how is use?
 rss.items.forEach(function(entry) {
 console.log(entry);
 });
 return res(rss);
 });
 });
};

I dont get the namespace fields from event. I would like to get those fields in the JSON without having to add customFields. How can I make use of stripPrefix option an use xml2js?
