xml external feeds to show on news site

Need assistance in implementing a xml feed from external source . This is currently already running on our site, but not correctly.
We have 2 sections (www.tophotel.news)
1.) Editors choice - Manuel added content
2.) xml feed from external source - we need to adjust in order to get the feed set up with different categories and also show in the different categories as shown in navigation.

Anybody with knowledge of feeds and scripts in order to get this working.

Thanks
Walter
