Bonsoir,

Hélas c'est bien la prmièe forme que tu exposes lami20j que je veux obtenir et ce que mamiemando m'a mis ne fonctionne pas, j'avais déjà essayé comme ça . . . :(
Si vous avez d'autres idées . . .

Alors en ce cas voilà le script, pareil il affiche le résultat sur STDOUT.

Si tu veux modifier le fichier sur place et tu ne sais pas le faire dit le.

Voilà le script ( faire une boucle et traiter ligne par ligne ce n'est pas laide)

#! /usr/bin/perl -w

$/=" ";
open FLIRE,'Zep3k!GnO.txt' or die "Impossible d'ouvrir le fichier : $!\n";
while (<FLIRE>){
s/\n\n<RENV/<RENV/;
print;
}


Et le résultat

[lamitest@localhost bin]$ cat Zep3k\!GnO.txt
blahblahblahblahblahblahblah

<RENV blahblah></RENV>blahblahblahblahblahblahblahblah
blahblahblahblahblah

<RENV blahblah></RENV>blahblahblahblahblahblahblahblah
