Get new elements within wp post

I have a special case, where the interesting content (PDF) is added weekly into the same old blogpost (wordpress). How to create the RSS feed containing links to the weekly PDFs?

Using .entry-content as the item selector, you’re only selecting one item, which isn’t what you want. Note also that CSS selectors use the dot notation to select HTML elements using their class attribute values. To select <blockquote> elements, leave out the dot.

Here’s an example:
