Hello all, Cultura FM radio has some interesting audios about classical music. I'd like to download it automatically. The steps are: 1. To get the page with http.request; 2. To match urls started with 'http://' and ended with '.mp3'; 3. To record the urls in a file. My problem is the step 2. I could not find a pattern to match urls like: http://midia.cmais.com.br/assets/audio/default/CENA_00087___P___24_12_10_1293450448.mp3 Let me show to you my attempt: local http = require('socket.http') local target = 'http://culturafm.cmais.com.br/cena-brasileira/cena-brasileira' local content, status = http.request(target) if status == 200 then local file = io.open('url.txt', 'w') local pattern = '(http://[a-zA-Z0-9_/]-%.mp3)' for url in content:gmatch(pattern) do file:write(url) end file:close() end Would someone know a lua pattern to match urls started with "http://"; and ended with '.mp3'?
