/** \mainpage irrXML 1.2 API documentation
<div align="center"><img src="logobig.png" ></div>
\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 <A HREF="http://xml.irrlicht3d.org" >xml.irrlicht3d.org</A>
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
<?xml version="1.0"?>
<config>
<!-- This is a config file for the mesh viewer -->
<model file="dwarf.dea" />
<messageText caption="Irrlicht Engine Mesh Viewer">
Welcome to the Mesh Viewer of the &quot;Irrlicht Engine&quot;.
</messageText>
</config>
\endcode
The code for parsing this file would look like this:
\code
#include <irrXML.h>
using namespace irr; // irrXML is located in the namespace irr::io
using namespace io;
#include <string> // 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. Basicly, this means you can do with
irrXML whatever you want:

warranty. In no event will the authors be held liable for any damages

2. Altered source versions must be plainly marked as such, and must not be
misrepresented as being the original software.
3. This notice may not be removed or altered from any source distribution.
\section history History
As lots of references in this documentation and the source show, this xml
parser has originally been a part of the
<A HREF="http://irrlicht.sourceforge.net" >Irrlicht Engine</A>. 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. With
irrXML 1.0, this has now been done.

pugixml 1.9 - an XML processing library
Copyright (C) 2006-2018, by Arseny Kapoulkine (arseny.kapoulkine@gmail.com)
Report bugs and download new versions at http://pugixml.org/
This is the distribution of pugixml, which is a C++ XML processing library,
which consists of a DOM-like interface with rich traversal/modification
capabilities, an extremely fast XML parser which constructs the DOM tree from
an XML file/buffer, and an XPath 1.0 implementation for complex data-driven
tree queries. Full Unicode support is also available, with Unicode interface
variants and conversions between different Unicode encodings (which happen
automatically during parsing/saving).
The distribution contains the following folders:
contrib/ - various contributions to pugixml
docs/ - documentation
docs/samples - pugixml usage examples
docs/quickstart.html - quick start guide
docs/manual.html - complete manual
scripts/ - project files for IDE/build systems
src/ - header and source files
readme.txt - this file.
