[LUA] function ExistItemByName(name) [9.6+]

[Critico]

About: I created this function because the function 'getItemIdByName(name)' no has the parameter 'false' to not display the error in console.

function ExistItemByName(name) -- by vodka
    local items = io.open("data/items/items.xml", "r"):read("*all")
    local get = items:match('name="' .. name ..'"')
    if get == nil or get == "" then
        return false
    end
return true
end

talk exemple:

function onSay(cid, words, param)
if not ExistItemByName(param) then
return doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE,"this item does exist")
end
return doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE,param.." ID: ["..getItemIdByName(param).."].")
end

So this don't work with < 9.6?

So this don't work with < 9.6?

works, but has no need to use.

parameter 'false' works in 9.6 <

in 9.6 < use try:

function onSay(cid, words, param)
if not getItemIdByName(param, false) then -- parameter false works
return doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE,"this item does exist")
end
return doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE,param.." ID: ["..getItemIdByName(param).."].")
end
