Hi,
I was trying to parse a XML file within a cocos2d-x project (XML file is required for the core game settings). After some exploration of the cocos2d-x code (which parses .plist file ) i was successfully able to parse my own Xml file. In the blog post http://www.siddhanttewari.com/site/?p=8 , i have shared C++ class which can be starting point for anyone doing a similar job.
