in reply to How to deal with long line

If the file is of modest size then read eveything into a string and:

my $str = <DATA>;
my @strs = $str =~ /START(.*?)END/g;
print join "\n", @strs;

__DATA__
somecharSTARTfvENDsomecharSTARTsvENDsomecharSTARTtvENDsomechar

Update: Change to read from a "file"

Monarch has suggested to me that this is likely to get pretty slow with HUGE files, and I agree. For very large files I'd suggest using this technique.

Perl is Huffman encoded by design.

    Thanks a lot it worked fine, I updated it to read from a file: 
    sub getInfoFromLongLine
{
    #Openning file for reading
    open(IFH,"$InputFile") || die "Can't open file: $InputFile\n";
    my $str = <IFH>;
    my @wanted_substrings = $str =~ /<A>(.*?)<\/A>/g;

 return "@wanted_substrings";
}
