youtube-opml-exporter-script's Issues

OPML file only has alphabetically-first 100 subscriptions

If the youtube account has more than 100 subscriptions, the channel list page loads with only the first 100 on it, in alphabetical order. When the browser scrolls to the bottom of the list, a POST request is triggered from a continuationItemRenderer, which causes more (the next 100, I think? my account has more than 100 but less than 200 subscriptions) to be loaded onto the page.

Since this script runs shortly after page load time, it can only see the first 100 subscriptions.

The contents of the script do get all subscriptions if you manually scroll to the bottom of the page, allowing the continuations to load all of the subscriptions onto the page, and then manually run it.

I have 2 ideas for changing the script to circumvent this:

1. When the script loads, check the page to see if there are any continuationItemRenderers, make the POST request that they would make, and wait for the new content to load. Repeat until there are no new continuationItemRenderers, then parse the page for channels.

2. Make the download be manually triggered, with a button on the page or something. Maybe add some language like "download OPML of subscriptions shown on this page". Alternatively, put the button on the bottom of the page, so the you have to scroll to get to it, and will trigger continuation loads when you do that.

Downloaded file has no newlines or tabs

Even though the href data is nicely formatted with newlines and indentation, all of it is lost when the file is actually downloaded. This makes it difficult to manually read the file.

Channels with "&" in their name produce invalid XML

For example, Mortise & Tenon Magazine.

The resulting XML

<outline text="Mortise & Tenon Magazine" title="Mortise & Tenon Magazine" type="rss" xmlUrl="https://www.youtube.com/feeds/videos.xml?channel_id=UCEqwYeNMlleNXKYiUwGN3Bw" />

should be

<outline text="Mortise &amp; Tenon Magazine" title="Mortise &amp; Tenon Magazine" type="rss" xmlUrl="https://www.youtube.com/feeds/videos.xml?channel_id=UCEqwYeNMlleNXKYiUwGN3Bw" />

which has the &s in the outline's text and title replaced with &.
