Wordpress plugin for XML feed to single posts -- 2

I'm currently building a new website with Wordpress which displays upcoming shows of local theaters. Those theaters works with an xml link, example: [login to view URL] (it's possible that you cannot access this because they had to whitelist the IP address of my hosting, so I added a copy of the feed as an xml file in the attachment. I tried several plugins like WP All Import, Feedzy, XML Import etc. to import this, but all plugins says the url is invalid. But when I open it in Safari I get a nice overview of all shows in a XML sheet. Therefore I would like to get my own plugin. Important is that I would like to customize the feed myself, so I want to choose which data I want to import and which not, because I don't need everything of the feed. Also important is that I could add more feeds. What I want: 1. Every day import update (automatically) with option to overwrite or delete posts; 2. All entries from the feeds imported as a single post, so nothing combined into one post (every show has to be one single post!); 3. Choose which tag should be matched with title, content, category (or choose an available one from the website), featured image, show date, link to original website. 4. Option to add more then just one feed (because of multiple theaters); Short version is that it actually has to work just like Feedzy, but then for XML feed.
