Loop over Fixtures

Trying to loop over all (patched) fixtures.

I found the info I needed in ShowData/LivePatch/IDTypes/Fixture

using commandline, I could navigate to that location like

cd ShowData
cd LivePatch
cd IDTypes
cd Fixture

when doing List , I have the list I need.

I tried to loop this list using LUA like:

local allFixtures = ShowData().LivePatch.IDTypes.Fixture:Children();
for allFixture in ipairs(allFixtures) do
    Printf(allFixtures[allFixture].no)
end

But no results or no error.

By thinking Fixture is a reserved word, I also tried local allFixtures = ShowData().LivePatch.IDTypes["Fixture"]:Children(); , but no luck

anyone any idea how to loop over this list correctly? thank you
