Convert Pattern of String into Table with Values

[Billy Peacock <spooky_loco_pv@...>]

I am trying to collect a range of Data from a string, that holds Data Values
example.. 
 assert(Table.Ammo.Signature == 'AMMO')
 assert(Table.Ammo.['Data Size'] == 194)

If anyone has any input on how to help me, i would appreciate it alot

Ammo = [[
  AMMO - Ammunition [0200FF03] <DLC1SoulCairnKeeperArrow> "Dragonbone Arrow"
    Record Header
      Signature: AMMO
      Data Size: 194

Anyone know how i can achieve this? I tried using this below
function StringLines( s, delim )
        local pos = 1
        local last = false
        return function()
                local starts, ends = string.find( s, '\n', pos, true )
                if starts then
                        if string.sub( s, starts - 1, starts - 1 ) == '\r' then
                                starts = starts - 1
                        end
                        local retStr = string.sub( s, pos, starts - 1 )
                        pos = ends + 1
                        return retStr
                elseif last then
                        return nil
                else
                        last = true
                        return s:sub( pos )
                end
        end
end

function ConvertToTable(data)
        KeywordPatterns = {
                "%s*AMMO - Ammunition [(%d+)] <([%w%C]+)>",
                "%s*Signature:%s*(%a+)",
                "%s*Data Size:%s*(%d+)"
        }

        local function PatternToTable(data)
                for a,b in pairs(KeywordPatterns) do
                        if data:find(b) then
                                print('found')
                                return select(2,data:find(b))
                        end
                end
        end

        for k,v in StringLines(data) do
                PatternToTable(data)
        end
end
