Parses an Array to XML, allows for multiple items with the same key, as long as the parent node is a collection. Useful for those nasty SOAP webservices with auto generated and poor WSDL

Hell yeah, 5 years have passed but I still find some nasty integrations that use XML.

Thanks for the snippet, works great

thx ;)

Cheers mate!

I can't even remember how this code works, happy to see people are still finding a use to it!
