Bonjour,

Je souhaiterais pouvoir, à partir de mon application télécharger des données sur une page Web.
Pour cela je dois fournir à cette page certaines informations issues de mon application.

Pourriez vous me dire comment pratiquer?

Voici le code de la page Web en question:
Code html : Sélectionner tout - Visualiser dans une fenêtre à part

L'application doit fournir le code ICAO, la date et heure les autres champs restent sans modification.
Elle doit récupérer le texte se trouvant sous la ligne horizontale.

Je joins également une screen de la page avec le texte à récupérer en bas (EDDK 110550Z 34006KT 6000 FEW005 BKN007 BKN012 17/16 Q1013 TEMPO 4000 BR BKN004)
