React Native RSS Feed reader issue - rss

Question

I am using React Native and trying to read and then parse an RSS Feed. I am following this tutorial:
https://getsiphon.com/docs/build-a-youtube-browser/
I am using a bit of the code, but trying to use a different RSS Feed. For example:
https://fivejs.codeschool.com/feed.rss
Here is the specific code I am having trouble with:
getNews() {
var url = "https://fivejs.codeschool.com/feed.rss"
fetch(url)
.then((response) => response.text())
.then((responseText) => {
const doc = new DOMParser().parseFromString(responseText, "text/xml");
var items = doc.getElementsByTagName('item');
var objs = []
for (var i = 0; i < items.length; i++) {
objs.push({
title: items[i].childNodes[0]
})
}
console.log("yay! made it here")
console.log("objs length: ", objs.length)
console.log("objs: ", objs[0])
})
.catch((error) => {
console.log('Error fetching the feed: ', error);
});
}
Everything is fine up to the point where I am console logging out the objs array. In other words I see the yay! made it here message and I also see the objs.length message (25). Once it gets to the next part I do not see the first item in the array.
As a note, I am building my code and running it in a iOS simulator using Xcode. I am not sure if the debug output console has anything to do with it, but I can't imagine it would since it does output the other messages. I even tried to console.log the items[i].childNodes[0] in the for loop and didn't get any results.

Not sure is this would help you but following the same tutorial for my own project i had to check two main points to make everything work:
Check the labels on your XML, sometimes this will mess up your parsing.
Inside the loop you can select another property. For example, in my case trying to parse a blog rss, i got "Item" (like 12 items) and inside that i get "Title" so i did this:
var item = doc.getElementsByTagName('item');
for(i=0; i < item.length; i++){
var title = item[i].getElementsByTagName('title');
console.log(title[0].textContent);
}
With this you can create an element (maybe a dictionary?) and then push it inside your array.
I hope this helps you in some way.
