<h1> TinyXML-2 </h1>

TinyXML is a simple, small, efficient, C++ XML parser that can be 
easily integrated into other programs.

The master is hosted on github:
github.com/leethomason/tinyxml2

<h2> What it does. </h2>
	
In brief, TinyXML parses an XML document, and builds from that a 
Document Object Model (DOM) that can be read, modified, and saved.

XML stands for "eXtensible Markup Language." It is a general purpose
human and machine readable markup language to describe arbitrary data.
All those random file formats created to store application data can 
all be replaced with XML. One parser for everything.

http://en.wikipedia.org/wiki/XML

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.

<h2> What it doesn't do. </h2>

TinyXML-2 doesn't parse or use DTDs (Document Type Definitions) or XSLs
(eXtensible Stylesheet Language.) There are other parsers out there 
that are much more fully
featured. But they are also much bigger, take longer to set up in
your project, have a higher learning curve, and often have a more
restrictive license. If you are working with browsers or have more
complete XML needs, TinyXML-2 is not the parser for you.

<h2> TinyXML-1 vs. TinyXML-2 </h2>

Which should you use? TinyXML-2 uses a similar API to TinyXML-1 and the same
rich test cases. But the implementation of the parser is completely re-written
to make it more appropriate for use in a game. It uses less memory, is faster,
and user far few memory allocations.

TinyXML-2 has no requirement for STL, but has also dropped all STL support. All
strings are query and set as 'const char*'. This allows the use of internal 
allocators, and keeps the code much simpler.

Both parsers:
<ol>
	<li>Simple to use with similar APIs.</li>
	<li>DOM based parser.</li>
	<li>UTF-8 Unicode support. http://en.wikipedia.org/wiki/UTF-8 </li>
</ol>

Advantages of TinyXML-2
<ol>
	<li>The focus of all future dev.</li>	
	<li>Many fewer memory allocation (about 1/100th), uses less memory (about 40% of TinyXML-1), and faster.</li>
	<li>No STL requirement.</li>
	<li>More modern C++, including a proper namespace.</li>
	<li>Proper and useful handling of whitespace</li>
</ol>

Advantages of TinyXML-1
<ol>
	<li>Can report the location of parsing errors.</li>
	<li>Support for some C++ STL conventions: streams and strings</li>
	<li>Very mature and well debugged code base.</li>
</ol>

<h2> Features </h2>

<h3> Memory Model </h3>

An XMLDocument is a C++ object like any other, that can be on the stack, or
new'd and deleted on the heap.

However, any sub-node of the Document, XMLElement, XMLText, etc, can only
be created by calling the appropriate XMLDocument::NewElement, NewText, etc.
method. Although you have pointers to these objects, they are still owned
by the Document. When the Document is deleted, so are all the nodes it contains.

<h3> Entities </h3>
TinyXML-2 recognizes the pre-defined "character entities", meaning special
characters. Namely:

@verbatim
	&amp;	&
	&lt;	<
	&gt;	>
	&quot;	"
	&apos;	'
@endverbatim

These are recognized when the XML document is read, and translated to there
UTF-8 equivalents. For instance, text with the XML of:

@verbatim
	Far &amp; Away
@endverbatim

will have the Value() of "Far & Away" when queried from the XMLText object,
and will be written back to the XML stream/file as an ampersand. 

Additionally, any character can be specified by its Unicode code point:
The syntax "&#xA0;" or "&#160;" are both to the non-breaking space characher. 
This is called a 'numeric character reference'. Any numeric character reference
that isn't one of the special entities above, will be read, but written as a
regular code point. The output is correct, but the entity syntax isn't preserved.

<h3> Printing </h3>

<h4> Print to file </h4>
You can directly use the convenience function:
@verbatim
	XMLDocument doc;
	...
	doc.Save( "foo.xml" );
@endverbatim

Or the XMLPrinter class:
@verbatim
	XMLPrinter printer( fp );
	doc.Print( &printer );
@endverbatim

<h4> Print to memory </h4>
Printing to memory is supported by the XMLPrinter.
@verbatim
	XMLPrinter printer;
	doc->Print( &printer );
	// printer.CStr() has a const char* to the XML
@endverbatim

<h4> Print without an XMLDocument </h4>

	When loading, an XML parser is very useful. However, sometimes
	when saving, it just gets in the way. The code is often set up
	for streaming, and constructing the DOM is just overhead.

	The Printer supports the streaming case. The following code
	prints out a trivially simple XML file without ever creating
	an XML document.

@verbatim
	XMLPrinter printer( fp );
	printer.OpenElement( "foo" );
	printer.PushAttribute( "foo", "bar" );
	printer.CloseElement();
@endverbatim

<h2> Using and Installing </h2>

There are 2 files in TinyXML-2:
<ol>
	<li>tinyxml2.cpp</li>
	<li>tinyxml2.h</li>
</ol>
And additionally a test file:
<ol>
	<li>xmltest.cpp</li>
</ol>

Simply compile and run. There is a visual studio 2010 project included.


<h2> Documentation </h2>

The documentation is build with Doxygen, using the 'dox' 
configuration file.

<h2> Contributors </h2>

Thanks very much to everyone who sends suggestions, bugs, ideas, and 
encouragement. It all helps, and makes this project fun.

The original TinyXML-1 has many contributors, who all deserve thanks
in shaping what is a very successful library. Extra thanks to Yves
Berquin and Andrew Ellerton who were key contributors.

TinyXML-2 grew from that effort. Lee Thomason is the original author
of TinyXML-2 (and TinyXML-1) but hopefully TinyXML-2 will be improved
by many contributors.
