[Lua - Action] finding an unspecific value in description/name of item?

[Ecstacy]

Hey,

I'm wondering if it's possible to find a value in the name/description of an item.

I.e.
"You see a sword [+X hp on click]"

And X are various values so I have to find the X value through a function, can this be done with string.find, and if so, how?

Thank you,

If you want to find a number, use:

local description = getItemAttribute(uid, 'description')
local result = description:find('%d+')

Thank you, exactly what I was looking for

edit:

How to make this work, so it remembers the value.

function find()
local description = "an item [+420 hp]"
local result = description:find("%d+")
print(result)
end

##Fixed it

local description = "an item [+115 hp]"
local p = 0
for s in description:gmatch("[%d+]") do 
if tonumber(s) ~= nil then
p = p .. '' .. tonumber(s)
end
end
if tonumber(p) > 0 then
print(tonumber(p))
else
print('0')
end
