Hi!
I have tried a solution.
Here my code.
I want to search for a city but in the function ort I will get an error like:
The operation select list item cannot accept the arguments: , [[[["GKZ", "10101"], ["Name", "Eisenstadt"], ["Region", "Gemeinde"], ["Warnstufe", "2"]], [["GKZ", "10201"], ["Name", "Rust"], ["Region", "Gemeinde"], ["Warnstufe", "2"]], [["GKZ", "10301"], ["Name", "Breitenbrunn am Neusiedler See"], ["Region", "Gemeinde"], ["Warnstufe", "2"]], [.....
The function warnstufe does work.
Hope somebody can help me.
kindly regards
This answers the example in your first post, hopefully you can work things out from there:
I attach an aia project file for you:
JSONWalk.aia (10.7 KB)
I had to use a small extension by @Hossein called List Utils, to sort the dates list.
