Category from template

Okay, I’ve hacked an ugly index.php that mostly does what I’m looking for, but there’s one little caviat: sometimes I need to have the download link be for a C file and sometimes for a CPP file.

Is there a way I can search the tags and if I see a CPP tag to change a variable?

Wanna see what I’ve got so far?

           $cats =  $cat->cat_name . ' ';   if(strstr("$cats", "Programs")  !== FALSE) {
             if(function_exists('the_ratings')) {
             /* Little PostRatings Mod */
             /* Replaces all <div> tags with <span> tags to fix display problems on some themes */
               ob_start();
               the_ratings();
               $remove_divs = ob_get_contents();
               ob_end_clean();
               echo str_replace('div', 'span', $remove_divs);

Sometimes I think I only ask so that I’ll find my own solutions.
