I confess LibXML doesn't create pretty XML, in fact I normally include variables to strip out the unneccesary whitespace because I send it through XSLT. You can write some kind recursive loop to fix it all or if you are not to worried about speed, send your string to XML::Twig
. It has some great pretty_print functionality. I only make the comment about speed because in this you will be effectively parsing your XML twice.
Edit by castaway: Closed small tag in signature
