I'm trying to integrate an outsystems app with sharepoint online.  Turns out being outside the Domain Forest makes web services calls next to impossible, so using REST calls retreiving an atom feed is another way.  I"m new to outsystems and thought there is probably an easy way to parst the XML doc and conver it to output on a page that is readable/usable for user.

Hi Dean,

The XML Records is what you're looking for. :)
If you need help using it please explore the component discussions (especially this one that went one for ages).

Cheers,
Davide
