Hi,
This is a sample of the variable given by Data::Dumper
function.
This function gives me the dump of the xml file into the
variable $VAR1.
$VAR1 = {
'Sample' => [
{
'books' => {
'ID' => '1',
'author' => 'my name.P',
'cost' => '300',
'edition' => '2',
'volume' => '2',
},
'seller' => 'amazon.com',
'discont' => '10%',
'date' => '22-2-02'
},
{
'books' => {
'ID' => '2',
'author' => 'my name.S',
'cost' => '40',
'edition' => '2',
'volume' => '1',
},
'seller' => 'amazon.com',
'discont' => 'none',
'date' => '22-2-02'
},
{
'books' => {
'ID' => '1',
'author' => 'my name.P',
'cost' => '300',
'edition' => '2',
'volume' => '2',
},
'seller' => 'amazon.com',
'discont' => '10%',
'date' => '22-2-02'
}
]
};
Now my question is after getting the values, I have 3 books
in my hash. How do i find out how many books, (ie., child
level nodes for sample) by perl code.
Thanks in advance.
Best regards
Prakash
