- - \section intro Introduction - - Welcome to the irrXML API documentation. - Here you'll find any information you'll need to develop applications with - irrXML. If you look for a tutorial on how to start, take a look at the \ref irrxmlexample, - at the homepage of irrXML at xml.irrlicht3d.org - or into the SDK in the directory \example. - - irrXML is intended to be a high speed and easy-to-use XML Parser for C++, and - this documentation is an important part of it. If you have any questions or - suggestions, just send a email to the author of the engine, Nikolaus Gebhardt - (niko (at) irrlicht3d.org). For more informations about this parser, see \ref history. - - \section features Features - - irrXML provides forward-only, read-only - access to a stream of non validated XML data. It was fully implemented by - Nikolaus Gebhardt. Its current features are: - - - It it fast as lighting and has very low memory usage. It was - developed with the intention of being used in 3D games, as it already has been. - - irrXML is very small: It only consists of 60 KB of code and can be added easily - to your existing project. - - Of course, it is platform independent and works with lots of compilers. - - It is able to parse ASCII, UTF-8, UTF-16 and UTF-32 text files, both in - little and big endian format. - - Independent of the input file format, the parser can return all strings in ASCII, UTF-8, - UTF-16 and UTF-32 format. - - With its optional file access abstraction it has the advantage that it can read not - only from files but from any type of data (memory, network, ...). For example when - used with the Irrlicht Engine, it directly reads from compressed .zip files. - - Just like the Irrlicht Engine for which it was originally created, it is extremely easy - to use. - - It has no external dependencies, it does not even need the STL. - - Although irrXML has some strenghts, it currently also has the following limitations: - - - The input xml file is not validated and assumed to be correct. - - \section irrxmlexample Example - - The following code demonstrates the basic usage of irrXML. A simple xml - file like this is parsed: - \code - - - - - - Welcome to the Mesh Viewer of the "Irrlicht Engine". - - - \endcode - - The code for parsing this file would look like this: - \code - #include - using namespace irr; // irrXML is located in the namespace irr::io - using namespace io; - - #include // we use STL strings to store data in this example - - void main() - { - // create the reader using one of the factory functions - - IrrXMLReader* xml = createIrrXMLReader("config.xml"); - - // strings for storing the data we want to get out of the file - std::string modelFile; - std::string messageText; - std::string caption; - - // parse the file until end reached - - while(xml && xml->read()) - { - switch(xml->getNodeType()) - { - case EXN_TEXT: - // in this xml file, the only text which occurs is the messageText - messageText = xml->getNodeData(); - break; - case EXN_ELEMENT: - { - if (!strcmp("model", xml->getNodeName())) - modelFile = xml->getAttributeValue("file"); - else - if (!strcmp("messageText", xml->getNodeName())) - caption = xml->getAttributeValue("caption"); - } - break; - } - } - - // delete the xml parser after usage - delete xml; - } - \endcode - - \section howto How to use - - Simply add the source files in the /src directory of irrXML to your project. Done. - - \section license License - - The irrXML license is based on the zlib license.

But because - the parser has become very useful with the latest release, people asked for a - separate version of it, to be able to use it in non Irrlicht projects.
