Text processing question

hello, the problemi is simple:

here's the input (.txt format):

##L
008L02C01---000225505
040L02C01---Agenti e rappresentanti
013L02C01---SEB Per 344.01
039L02C01---[SEB Per 344.01] ####2(2002)-
##L
008L02C01---000225469
040L02C01---Ambiente
013L02C01---SEB Per 344.046
039L02C01---[SEB Per 344.046] ####10(2002)-
##L
008L02C01---000186787
040L02C01---Ambiente & sicurezza
013L02C01---SEB Per 344.046
039L02C01---##2(2000)- (SEB Per 344.046)
##L
008L02C01---000228903
040L02C01---Amministrazione civile
013L02C01---SEB Per 351
039L02C01---[SEB Per 351] ####2002-

and I'd like to obtain the following "polished" output:

Agenti e rappresentanti
SEB Per 344.01
2(2002)-

Ambiente
SEB Per 344.046
10(2002)-

Ambiente & sicurezza
SEB Per 344.046
2(2000)- (SEB Per 344.046)

Amministrazione civile
SEB Per 351
2002-

is it possible?

thanks a lot,

Very quick and dirty:
#!/usr/bin/perl -w

use strict;

while (my $s = <>) {
chomp $s;
if ($s =~ /##L/) {
$s = <>;
$s = <>;
chomp $s;
my @t = split /---/, $s;
print $t[1], "\n";
$s = <>;
chomp $s;
my @t = split /---/, $s;
print $t[1], "\n";
$s = <>;
$s =~ /#+(.+)/;
print $1, "\n\n";
}
}

dda

Run it as perl script.pl infile.txt > outfile.txt

hello,
thanks for the quick answer

with windows NT + active perl Build 515 Friday, April 9, 1999 I obtainde the followingf error from the DOS shell:

C:\prl>vedi.pl kris.txt > kris2.txt
"my" variable @t masks earlier declaration in same scope at C:\prl\vedi.pl line
15.
Use of uninitialized value at C:\prl\vedi.pl line 19, <> chunk 235.

If you can delete these errors, all goes OK

bye

if I call the script as follows (in the worng manner..)

C:\prl>vedi.pl kris.txt

without output file, I obtain the right result on the STDOUT (the msdos shell)

hope it helps

Hello,

"my" variable @t masks earlier declaration in same scope at ved
Use of uninitialized value at vedi.pl line 19, <> chunk 235.

everyway thanks: I've accepted the answer.

Yes, it's my fault. Please just remove second 'my' from tge script:

#!/usr/bin/perl -w

use strict;

while (my $s = <>) {
chomp $s;
if ($s =~ /##L/) {
$s = <>;
$s = <>;
chomp $s;
my @t = split /---/, $s;
print $t[1], "\n";
$s = <>;
chomp $s;
@t = split /---/, $s;
print $t[1], "\n";
$s = <>;
$s =~ /#+(.+)/;
print $1, "\n\n";
}
}

Regards,
Dmitry.
