I am parsing a file and coloring text that matches certain words but do not want to color text if these keywords are part of a string literal or part of a commented statement. The code to parse the file and color the keywords is as follows: 
         my @words = ("while", "foreach", "loop");
         foreach my $word (@words) {
            my $word_len = length $word;
            my $next = "1.0";
            while (my $from = $t->search(-regexp, "\\b$word\\b", $next
+, "end")) {
               $next = "$from + $word_len chars";
               $t->tagAdd("green", $from, $next);
               $t->tagAdd("bold", $from, $next);
            }
         }

What is the best way to ignore a string or a commented statement and ignore these only, during the parsing?

In reply to need to recognize string literals and ignore then during parsing. by Elijah
