XML::Simple XML / XMLin / XMLout? or something else?

[Roboz]

Hello Perl Monks! I have an XML file similar to the following:

<booklist>
   <book>
      <author>Book 1 author 1</author>
      <author>Book 1 author 2</author>
      <title>Book 1 title</title>
      <isbn>Book1ISBN</isbn>
   </book>
   <book>
      <author>Book 2 author 1</author>
      <author>Book 2 author 2</author>
      <title>Book 2 title</title>
      <isbn>Book2ISBN</isbn>
   </book>
   <book>
      <author>Book 3 author 1</author>
      <author>Book 3 author 2</author>
      <author>Book 3 author 3</author>
      <title>Book 3 title</title>
      <isbn>Book3ISBN</isbn>
   </book>
</booklist>

I would like to loop through this file and output each book's XML code including the opening and closing book tags. I've tried parsing the XML file with XML::Simple using XMLin and that gives me a data structure like so:

$VAR1 = {
          'book' => [
                    {
                      'isbn' => 'Book1ISBN',
                      'title' => 'Book 1 title',
                      'author' => [
                                  'Book 1 author 1',
                                  'Book 1 author 2'
                                ]
                    },
                    {
                      'isbn' => 'Book2ISBN',
                      'title' => 'Book 2 title',
                      'author' => [
                                  'Book 2 author 1',
                                  'Book 2 author 2'
                                ]
                    },
                    {
                      'isbn' => 'Book3ISBN',
                      'title' => 'Book 3 title',
                      'author' => [
                                  'Book 3 author 1',
                                  'Book 3 author 2',
                                  'Book 3 author 3'
                                ]
                    }
                  ]
        };

I'm really at a loss as how I would loop throught this to output the XML. I think the data structure is confusing me. I need the XML chunks to be identical to the input. I'm assuming I would use XMLout. Or maybe something completely different? Thanks in advance for any pointers!
