i wrote a small programm which notifys me on my android, when a button is pushed

Code: Select allpin = 4
gpio.mode(pin,gpio.INPUT)

function buttonpressed()

if gpio.read(pin)== 0 then
     conn=net.createConnection(net.TCP, false)
     conn:on("receive", function(conn, pl) print(pl) end)
     conn:connect(80,"50.116.34.97")
     conn:send("GET /publicapi/notify?apikey=MYAPIKEY&application=ESP8266&event=START&description=Der%20Schalter%20wurde%20gedrückt\r\n"
          .."Connection: keep-alive\r\nAccept: */*\r\n\r\n")
     tmr.delay(500000)
end

end

tmr.alarm(0, 100, 1, function() buttonpressed() end )


It works fine and when i push the button, i get this payload ( pl ) printed on the serial terminal :

Code: Select all<?xml version="1.0" encoding="UTF-8"?><nma><success code="200" remaining="989" resettimer="45"/></nma>


But how can i save the payload to a string / char and search for words like " success code" or "resettimer="?
Or is there a way to save the payload and let a command search a character at a specfied place?

Sorry for my English, I'm a young student from Germany

But i couldn't find the examples by Xchip
