I’d 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 = xml.collected(viewFromXML,"/connection") for i=#relationTable, 1, -1 do connectionFromXML = relationTable[i] parseXMLConnection( rootFromXML, connectionFromXML, viewFromXML, rootFromOverrideXML) end
But apparently my lua knowledge is lacking (severely, I might say) as this ends with “attempt to get length of a function value “
What is the correct way to do it?

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.

It had been awhile, so for the record.
I was looking for something similar and found out that adding a third argument to the xml.collected reverses the iterations. Looks like the argument has to be true in a boolean sense, so puting any "string" there will do the trick.
for v in xml.collected(doc, "/chapter/section", "string") do ... end
