Need Help??

in reply to foreach not doing what I expect it to be doing

You are creating an array with only a single element. That single element happens to be an array reference. So the foreach loop is working how you expect, it's your earlier assignment that isn't. You might have better luck by dereferencing the arrayref on assignment (note, this makes a copy. Depending on the circumstances, that may be bad):

my @bucketList = @{ $_xmlData->{Bucket} };
...

See also perlreftut for a nice references tutorial, or perlref for the full reference docs.

Also, but not related to your problem, you should open your bucket.txt only once, otherwise it'll be overwritten on each iteration. `open(DEBUG, ">bucket.txt"); foreach my $bucket ( @bucketList ) { print DEBUG Dumper($bucket); } close(DEBUG);` [download] -- 6x9=42	[reply] [d/l]

That, or open it with `>>` instead of `>`. But your solution is better overall, I am just stating a TIMTOWTDI. Update: Mental note, read all replies before responding!	[reply] [d/l] [select]
