Thanks Graf, your algo worked like magic. But there is one issue. Some of the tags may have a null value.

In that case, hash key is not getting assigned.

EG:

<root>
<tag1></tag1>
<tag2>My Tag2</tag2>
<tag3>My Tag3</tag3>
</root>

So for the above case, hash data structure should be:

my %my_hash = (
        tag1 => undef,
        tag2 => 'My Tag2',
        tag3 => 'My Tag3',
    );
