Wise Monks,

While I'm reading Learning Perl, I stumble across exercise #2 in Chapter 9. The answer goes like this:

@ARGV = '/path/to/perlfunc.pod';

while(<>) {
  if (/^=item\s+([a-z_]\w*)/i) {
  print "$1\n"
 }
}

This is supposed to pull out and print all lines that start with =item and are followed by a Perl identifier name. So using this, I wrote something that should do something similar.

sub findtext {
@filenumbers = @_;
foreach $number(@filenumbers) {
push @filenumbers2, split(/\W/, $number);
}
    foreach $number(@numbers2) {
    chomp $number;
    if( defined $number ) {
        open(FILE,"/home/jroberts/$number.txt") or die "$!";
        foreach $term(@inputs) {
        while(<FILE>)
            if(/\b($term)\b/i) {
            push @before, split(' ', $`);
            @before = reverse(@before);
            @before = splice(@before, 0, 7);
            @before = reverse(@before);
            push @after, split(' ', $');
            @after = splice(@after, 0, 7); 
            if(exists $results{$number}) {
            $existing = $results{$number}; 
            $results{$number} = $existing . "... @before" . "<b>$&</b>
+" . "@after ...";
            } else {
            $results{$number} = "... @before" . "<b>$&</b>" . "@after 
+";
            }
            @before = undef;
            @after = undef;
            next;
            } else {
            print "No Match\n";
            next;
            }
        }
        print "Match found in $number.txt\n";
        @fulltext = $results{$number};
        print "@fulltext\n";
        close(FILE);
    } else {
    next;
    }
    next;
    }
}

When I put terms into @inputs using @ARGV, this only prints the first match it finds, even though there are more, also additional $term values don't get matched. I know this can be done using grep, but I wanted to write it in perl.
