note Jenda <code> use XML::Rules; my $parser = XML::Rules->new(rules => {}, ident => ' '); print $parser->toXML( Shelf_Info => { switch => [ {Name => "Puebla01", shelfType => [7480], commentText => ['ATM Core switch']}, {Name => "Puebla02", shelfType => [7440], commentText => ['ATM access switch']}, ] }); </code> <p>Not XML::Smart though. It makes use of the fact that the value of a tag attribute may only be a single string, not a hash or array so it's clear that the shelfType and commentText must be a child tag, not an attribute. Generally XML::Rules attempts to create the simplest possible XML that'd contain the data and attribute is considered simpler than child tag.</p> <p><b>Update:</b> With version 1.16 I just uploaded to CPAN, it'd be even simpler:</p> <code> use XML::Rules ToXML => { ident => ' ' }; print ToXML( Shelf_Info => { switch => [ {Name => "Puebla01", shelfType => [7480], commentText => ['ATM Core switch']}, {Name => "Puebla02", shelfType => [7440], commentText => ['ATM access switch']}, ] }); </code> <p>You may now instantiate a parser and import a subroutine that'll call the specified method on that instance to simplify the usage.</p> <!-- Node text goes above.
