chanakya,
Since you have omitted details of your requirements I am going to guess that you know you have an AoHo(H or A) and that you want the keys of the second level H and corresponding values of the (H or A) regardless of which it is.

for ( @$data } {
    print "$_ =>";
    if ( ref $_ eq 'ARRAY' ) {
        print join ", ", @$_;
    }
    else {
        print join ", ", sort values %$_;
    }
    print "\n";
}

Note: You may have to modify this a bit to get a specific order with your hashes if the simple sort I provided isn't satisfactory. You will also have to modify the depth of ref depending on how many levels deep you need to go. IOW - this isn't fully working code but an idea of how to get started.

Update:Data::Dump::Streamer and/or Data::Dumper may also be of some help. As socketdave points out, your data structure is missing commas and unbalanced and it is hard to say for sure what you want without some more specifics

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
