There are different ways to access and interact with XML data. TinyXML-2 uses a Document Object Model (DOM), meaning the XML data is parsed into a C++ objects that can be browsed and manipulated, and then written to disk or another output stream. You can also construct an XML document from scratch with C++ objects and write this to disk or another output stream. You can even use TinyXML-2 to stream XML programmatically from code without creating a document first. TinyXML-2 is designed to be easy and fast to learn. It is one header and one cpp file. Simply add these to your project and off you go. There is an example file - xmltest.cpp - to get you started. TinyXML-2 is released under the ZLib license, so you can use it in open source or commercial code. The details of the license are at the top of every source file. TinyXML-2 attempts to be a flexible parser, but with truly correct and compliant XML output. TinyXML-2 should compile on any reasonably C++ compliant system. It does not rely on exceptions, RTTI, or the STL.

Almost all applications on your server, desktop, laptop or mobile device store data in the form of mass data, e.g. photos, binary files or documents and as meta data objects (key,value-pairs), e.g. blog entries, address records or geographical location information. Existing cloud services offer different interfaces for application integration to achieve nearly the same: to store mass and meta data in the cloud. SharpBox abstracts existing proprietary technologies under a clear, easy to use and reliable API available on the most important platforms in the industry (Windows, Linux, MAC, Windows Phone 7, Android and iOS). Do you want to write code for storing data in the cloud only once in your application? SharpBox is the right free open source solution for your project. Our goal is to disburden software projects from the demand to implement storage access twice to support a wide range of storage clouds. Are you a cloud storage service provider and do you want to offer your platform for a growing community of software developers and ISVs? SharpBox is the right free open source solution under the MIT license. Just contact us or start writing your own cloud storage service provider, based on our integration API for storage vendors.
