I'm afraid I'm having difficulty understanding the question. You must have
*some* way to know which elements you want to ignore!

You hven't told us what $canal is!

You're retrieving another document from the database here, but you haven't
told us what's in it!

You haven't told us what's in $show.

You haven't told us what's in $default.

I don't understand the relationship of this output to your input. Where do
the numbers 2,4,5 (and 1,2,3) come from?

It's difficult to understand the question, but the problem is nothing to do
with your grammar, which is perfect!
