Monks, Here is my xml file

<booklist>
   <book type="technical">
      <author>Book 1 author 1</author>
      <author>Book 1 author 2</author>
      <title>Book 1 title</title>
      <isbn>Book1ISBN</isbn>
   </book>
   <book type="fiction">
      <author>Book 2 author 1</author>
      <author>Book 2 author 2</author>
      <title>Book 2 title</title>
      <isbn>Book2ISBN</isbn>
   </book>
   <book type="technical">
      <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>

Here is my perl code to parse it:

use XML::Parser;

# initialize parser and read the file
$parser = new XML::Parser( Style => 'Tree' );
my $tree = $parser->parsefile( shift @ARGV );

# serialize the structure
use Data::Dumper;
print Dumper( $tree );

And here is the output:

HOW TO ACCESS INDIVIDUAL ELEMENTS? How will they get stored in hash table? For example, I am interested in having "type" of the book.

Thanks in Advance,
