Apologies but 2 questions for you today regarding WWW:Mechanize:

1) When using the $mech->follow_link(...) $mech->find_link( ... ) if one wanted more than 1 conditional for selecting links what would the syntax be for doing this e.g

my @cgi_links = $mech_cgi->find_all_links( url_regex => qr/protein/ );
[download]

but the following does'nt?

my @cgi_links = $mech_cgi->find_all_links( url_regex => qr/(protein &&
+ amino)/ );
[download]

Can anyone point me in the right direction or know the answer?

2) what is the best practice for only following/selecting the same link once and not following it again multiple times if the link is present more than once on a web-page?

many thanks and best wishes

Dan
