Hello guys,

So I finally managed to get an RSS feed outputting the items I wanted it to (it wasn't easy, and still isn't properly correct, but I can live with the caveats for the time being.)

However, the feed spits out content seemingly from other areas of the site, image I have the following structure (I thought this could be down to page inheritance, maybe it was spitting out the content of an inherited master, but alas, I have set the master to 'none' for the NewsRssFeed page and it still gets outputed):

Media
  News
    NewsItem1
    NewsItem2
    NewsItem3
  NewsRssFeed

I use the following selector in my RSS XSLT:

$currentPage/descendant::*

And the output is similar to this:

<channel>
  <title></title>
  <link></link>
  <pubDate/>
  <generator></generator>
  <description></description>
  <language>en</language>
  <item>...</item>
  <item>...</item>
  <item>...</item>
A bunch of page content is written here!
</channel>

Here is the XSTL in full:

Perhaps the most peculiar part is that what is being outputted is very definitely on a page somewhere (I found some of the content on the About page) but it doesn't have this content in full, just a paragraph or so, and it starts with a number: maybe some keywords and DateTimes; below is an example:
