Merci

Tu peux me redonner le lien vers le post principal afin que je puisse voir la manière d'appeler les fonctions stp ?

[labomatik]

ça vient du module météo de Steven. 

[Krikroff]

Aussi une lib XML dans mon framework LUA cf. Code du module Sonos

Mais celui de Steven me semble plus léger dans le bon sens !
