For the second question, see Extract field values example on the wiki:
...
57 -- extract the field into a table of FieldInfos
58 finfos = { field() }
59
60 if #finfos > 0 then
61 -- add our proto if we haven't already
62 if not tree then
63 tree = root:add(exproto)
64 end

66 for _, finfo in ipairs(finfos) do
...
The EASYPOST.lua script wiki:lua#examples does something similar.
This allows processing all instances of a field in a packet.
-- copy existing field(s) into table for processing
finfo = { easypost_payload_f() }
if (#finfo > 0) then
if not subtree then
subtree = tree:add(easypost_p)
end
for k, v in pairs(finfo) do
