I’d like to travese the contents of an xml.collected() in a reverse order. I have

I tried:

But apparently my lua knowledge is lacking (severely, I might say) as this ends with “attempt to get length of a function value“

it's an iterator

What is the correct way to do it?
xml.all

Tried to find documentation, but failed.

Tried this:

    local relationTable = xml.all(viewFromXML,"/connection")
    for i=#relationTable, 1, -1 do
      connectionFromXML = relationTable[i]
      parseXMLConnection( rootFromXML, connectionFromXML, viewFromXML, rootFromOverrideXML)
    end

but it fails as well.
