Lua and patterns workaround

Good day, I ask if someone could help me for doing this in this way in lua. I have a string that contains name of files (including complete fullpath) separated by a "|", at the end is a number who indicated the current file (is for a player). So I just wanna keep it with the name of the files, but right now I have to use match function 2 times, one for separation and the other for cut it out the path. I wonder if and how is possible to do this with only one. Ex. I have:

local s = "W:\\Videos\\Tokyo Ghoul\\[Tokyo Ghoul][EP01]Tragedia.mkv|W:\\Videos\\Tokyo Ghoul\\[Tokyo Ghoul][EP02]Incubación.mkv|W:\\Videos\\Tokyo Ghoul\\[Tokyo Ghoul][EP03]Paloma.mkv|W:\\Videos\\Tokyo Ghoul\\[Tokyo Ghoul][EP04]Cena.mkv|2";

So i do:

for val in s:gmatch('(.-)|') do
    print(val);
    table.insert(list, {
            type = "item",
            icon = icon;
            text = val:match(".*\\(.*)")});
end

I receive:

[Tokyo Ghoul][EP01]Tragedia.mkv
[Tokyo Ghoul][EP02]Incubación.mkv
[Tokyo Ghoul][EP03]Paloma.mkv
[Tokyo Ghoul][EP04]Cena.mkv

What I want is just use only one gmatch function. Hope someone can help me.
