[Thomas Vollath]

Here is an excerpt xml of a fictional YouTube channels videos:

When setting up a new Feed in the Xenforo ACP you can access a few tags in the message template:
{title} {content} {author} {link}

My question is how can I parse other tags from the xml? I can parse {id} and a few others, but none of the tags with ":" in them work.

What I am trying to achieve is to parse the "yt:videoId" in to a media=youtube bbcode like this:

[media=youtube]{yt:videoId}[/media]

In general, parsing tags other than what's available by default would require custom development.
