Re^2: Make CSV list from values in AoH

Thanks very much, Rolf.

All your solutions seem to work to my original spec's, thanks!

Sorry to report that I forgot to mention that if there are no names, the output should be 2 single quotes (see update in my first post).

I've come up with this, which is based on your 1st solution:
$csv = "'" . (join "','", map{$_} map{$AoH[$_]{name}} 0..$#AoH) . "'";
or more simply:
$csv = "'" . (join "','", map{$AoH[$_]{name}} 0..$#AoH) . "'";
or even:
$csv = "'" . (join "','", map{$_->{name}} @AoH) . "'";

BTW, how do I merge the 2 maps you mentioned into 1?

Your approach is not advisable. Just imagine you need to change the quote from ' to ", then you'll have to change 4 code places instead of 2. depends what "if there are no names" means. the key "name" is missing the value for "name" is "" the value for "name" is undef `map{ $AoH[$_]{name} \|\| "" }` should cover all cases except if the name "0" is not allowed (untested) good night! :) Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery FootballPerl is like chess, only without the dice}	[reply] [d/l]

Thanks Rolf. Good point - sorry for the ambiguity. Basically meant the key "name" is missing. Actually, the @AoH will be empty to there won't be any keys. I'm not sure how I can use: map{ $AoH$_{name} \|\| "" } in context. Is that what you meant by merging the two maps into one? But I'm pretty happy with the other stuff you've given me, thanks for your help. Good morning...from NZ.	[reply]
