How to get the values by the index Lua

Hello there I'm new in Lua and a have a question, I have this code:

dialogExample = "1. han3x1 2. 1kekeo 3. 103kdo 4. 54o4as 5. asbf1c 6. ask6os"

for k in string.gmatch(dialogExample, "[^%s]+") do
    print(k)
end

output:

1. 
han3x1
2.
1kekeo
3.
103kdo
4.
54o4as
5.
asbf1c
6. 
ask6os

How can I get the the values by the index, for exemple, I just want to print the value of the line 1. in this case "han3x1", How can I do this?

I want get just the "1. han3x1", after I just want the value "4. 54o4as". But these values are random

I appreciate any help, thank's

Just use a table

-- table with index keys from 1 to 6
dialogExample = {"han3x1", "1kekeo", "103kdo", "54o4as", "asbf1c", "ask6os"}

for i = 1, #dialogExample do
    io.write(('%d.\n%s\n'):format(i, dialogExample[i]))
end

Output:

1. 
han3x1
2.
1kekeo
3.
103kdo
4.
54o4as
5.
asbf1c
6. 
ask6os

Than...

io.write(('%d.\n%s\n'):format(1, dialogExample[1]))

Output:

1.
han3x1

perhaps your case describes a pattern like this:

local dialogExample = "1. han3x1 2. 1kekeo 3. 103kdo 4. 54o4as 5. asbf1c 6. ask6os"
local t = {}
for i,v in string.gmatch(dialogExample, "(%d+)[%.%s]*([^%s]+)") do
    t[i] = v
    print(i,t[i])
end

out:

1    han3x1
2    1kekeo
3    103kdo
4    54o4as
5    asbf1c
6    ask6os
