I=E2=80=99d like to travese the contents of an xml.collected() in a =
reverse order. I have

    for connectionFromXML in xml.collected(viewFromXML,"/connection") do
      parseXMLConnection( rootFromXML, connectionFromXML, viewFromXML, =
rootFromOverrideXML)
    end

I tried:

    local relationTable =3D xml.collected(viewFromXML,"/connection")
    for i=3D#relationTable, 1, -1 do
      connectionFromXML =3D relationTable[i]
      parseXMLConnection( rootFromXML, connectionFromXML, viewFromXML, =
rootFromOverrideXML)
    end

But apparently my lua knowledge is lacking (severely, I might say) as =
this ends with =E2=80=9Cattempt to get length of a function value =E2=80=9C=


What is the correct way to do it?
