Selectors - avoid duplicates

[mmjaeger]

Hello
I'm having the following piece of code: $$('a[rel=external]','a
[target=_blank]')

this basically returns all links that have either or both of the rel/
target attributes - how do I avoid duplicates?

Is there a way just by the selector or some array mapping function?

thanks

What do you mean by "duplicates"? The same element should not be
returned twice even if it matches more than one of the passed
selectors.

Have you even checked this code? It's not returning any duplicates: http://mooshell.net/yFUTA/

you guys are right - what confused me was that on a client site I all
the sudden saw two pictures on the link instead of one - my first
thought was that the picture gets applied to the link twice - however,
there were two links next to each other and one of them had no text.

thanks anyway
