if using
$content =~ s/(\w+)(: *)(.*)\n<xxxxyyxxxx>\n/$1.":".$2.encode_base64($
+3,'')."\n"/ges;

[download]
it works but it takes the biggest text segment, not the smallest one which i want.
to answer to tall_man, i'm trying to clean the ldif output from mozilla to get standard ldap to include in a directory.
so i get a file with multiple 
cn: dn=toto
sn: XXX
description: YYY

[download]

some of them base64 encoded, i have to decode them, for cn, add a good suffix, remove others, reformat ones, ...
some of theses base64 fields contains multiples lines and at the end of the conversion (reencoding base64) my file has:
cn: dn=toto
sn: XXX
description: YYY
yyyy
<xxxxyyxxxx>

cn: dn=toto2
sn: XXX2
description: YYY2

cn: dn=toto3
sn: XXX3
description: YYY3
tttt
uuuuuu
<xxxxyyxxxx>

[download]

$content =~ s/(\w+)(: *)(.*)\n<xxxxyyxxxx>\n/$1.":".$2.encode_base64($
+3,'')."\n"/ges;

[download]

=> encode the largest matching
$content =~ s/(\w+)(: *)([^\n]*)\n<xxxxyyxxxx>\n/$1.":".$2.encode_base
+64($3,'')."\n"/ges;

[download]

=> doesn't match field with more than 1 lines. i hope have been clearer.

thanks
