util.datamapper: Factor out extraction of the XML part to use So extract_value() takes an XML tag and details about which part we're interested in and returns that. Factoring this out will help with array implementation since this will be common behavior.

local type renderer = function (string, { string : any }) : string
local type filter = function (string, any) : string
local record lib
	new : function (string, string, funcs : { string : filter }) : renderer
end
return lib
