It depends on what parts are constant? does all the strings you want to match start with "[[Datie" and have the exact amount on brackets? If so you can try this [[Datei.*[[.*]].*]]. And if its the one after "text" the try text [[.*[[.*]].*]].
But be aware that if you don't know the number of brackets then it can be tricky, but you need some assumption about them, because it's impossible to make a regular expression that matches an unknown amount of brackets. (For that you will need a stack - managed by you.)
