Array and hash problems. 2

[peterneve]

I am susing XML::Simple to read an XML file. I have forced it to use arrays, so I can access items like this:

  print "$config1->{level1}->[0]->{level2}->[0]->{level3}->[0]";

This is great, but level3 is a hash and I want the keys of the hash. If I use something like:

  %hash=$config1->{level1}->[0]->{level2}->[0];
  @keys=keys(%hash);

I just get: HASH(0x23a11d4)

I know this probably just need dereferencing somehow but I can't work it out.

Any ideas? ;-)

Thanks in advance...

Try this:

@keys = keys(%{$hash});

Maybe:

%hash=[COLOR=red]%{[/color]$config1->{level1}->[0]->{level2}->[0][COLOR=red]}[/color];
@keys=keys(%hash);
