I'm trying to build a Perlscript to extract data from a ton of text files.
From the command line, I'd like to run the following 
ls *.txt | myscript.pl

[download]
where myscript.pl looks something like this: 
#!/usr/bin/perl -w

my $filename = "";
my $inputline = "";
my $siteid = "";
my $sitename = "";

foreach $filename (@ARGV){
    open(FILE,$filename) or die "can't open file: $!\n";
    print "processing $filename\n";

    while ($inputline = <FILE>){
        if ($inputline =~ m/^Station/){
           print "$inputline\n";
         }
}
        close FILE;
}

I've seen other code snippets using a pipe in the open(), but I'd rather do it as shown if possible. Any help appreciated. If I must use a pipe in open(), how can I iterate through the results of ls *.txt?

update (broquaint): added <code> tags and dropped extraneous <br> tags
