XML Twig is so confusing. Is there any post which explains xml twig in detail? Regexp i cannot use, the parameters are determined by nodes and thus it fails. Can you suggest some good and easy to use module. I have tried hell lot of modules some are good parsers and some are good modifiers but i am unable to find a module which is a good parser as well writer of XML. Be notified I cannot afford to change my output xml parameters locations.
