Hi Jenda,

Your code worked like a magic. Thanks a bunch for that.

However my actual XML file is slightly different than the one I posted previously.

Following is my actual XML file: 
<root>

<!-- First Element -->
<start_element>

<header>
<element_num>1</element_num>
</header>

<contents>
<child>MyChild</child>
</contents>

</start_element>

<!-- Second Element -->
<start_element>

<header>
<element_num>2</element_num>
</header>

<contents>
<child>MyChild</child>
<userID>MyUser</userID>
</contents>

</start_element>

<!-- Third Element -->
<start_element>

<header>
<element_num>3</element_num>
</header>

<contents>
<child>MyChild</child>
</contents>

</start_element>

</root>

I tried your old code for this XML file but it didn't work. I guess some modification is needed. I am a very early beginner to modify your code. Could you please guide me to make the necessary change.

Also I am trying to provide the XML file as an input parameter. For that I have slightly modify your code but somehow its not working as shown below. Any pointers?

use strict;
use warnings;
no warnings 'uninitialized';

use XML::Rules;

my $parser = XML::Rules->new(
    rules => {
        _default => 'raw extended',
        start_element => sub {
            my ($tag,$attr,$context,$parents,$parser) = @_;

            print {$parser->{parameters}[( exists $attr->{':userID'} ?
+ 0 : 1 )]} $parser->ToXML( $tag, $attr);
        }
    }
);

open my $FH1, '>', 'test1.xml';
open my $FH2, '>', 'test2.xml';
open my $FH3, "$ARGV[0]";

print $FH1 "<root>\n";
print $FH2 "<root>\n";
$parser->parse( <$FH3>, [$FH1, $FH2]);
print $FH1 "\n</root>\n";
print $FH2 "\n</root>\n";

And if you could please explain your code line by line it will be great as I am really curious to know how is it working and significance of each & every line and each & every method. :)
