Open a file automatically with a specific application in Safari

Do you know if it's possible to automatize this process?

No.

No prioritization possible with the current iOS incarnation. Any app that reports to the system its capability to open docs of that kind will get listed.

In days of yore before tablets were born, pre-OSX versions of Mac OS imposed two 4-letter ID tags on all files stored within. Type and Creator, they were called. It was a cinch to place which opened what. When Unix came and conquered, such niceties went out the window. Now you only have the filename suffix to divine what gets to open the file. And some suffixes (like .txt or even .doc) are severely overloaded: EVERYONE claims to be able to deal with them, regardless. With iOS, the mandatory sandboxing the apps live in adds more interesting wrinkles to the party.

The folks at the Developer forums, both the public ones here at the ASC or over in the private ones, would be happy to discuss the intimate details.

I do not think that is possible.

Courcoul touches on what is probably the case here. Sounds like you want to develop an app and make it the default for opening a particular type of file.

As has been stated here already, this is not possible using iOS today.
