XML - Simple

djbryson has asked for the wisdom of the Perl Monks concerning the following question:

I have multi level XML
I figured out how to extract whatever parts I want like so:

print $data->{channel}{item}[3]{title};
or
print $data->{channel}->{item}[3]->{title};
[download]

How can I loop through this and output?
So, I have a hash called "channel" that contains an array called "item" which contains another hash called "title" correct? So, if I want to loop all the titles, what's the syntax?

Most likely you will find tye's References Quick Reference most useful. Alternatively look at perldsc.	[reply]

Do what Corion suggested and read References Quick Reference. After reading the above quick reference, the code `foreach my $key (keys %{$hash_ref})` will mean something to you and be your friend (if you are not sure what that line does, check out the perldocs).	[reply] [d/l]
