RapidXml is a very fast and stable XML

XML

Extensible Markup Language is a set of rules for encoding documents in machine-readable form. It is defined in the XML 1.0 Specification produced by the W3C, and several other related specifications, all gratis open standards....

 DOM

Document Object Model

The Document Object Model is a cross-platform and language-independent convention for representing and interacting with objects in HTML, XHTML and XML documents. Aspects of the DOM may be addressed and manipulated within the syntax of the programming language in use...

-style parser written in C++

C++

C++ is a statically typed, free-form, multi-paradigm, compiled, general-purpose programming language. It is regarded as an intermediate-level language, as it comprises a combination of both high-level and low-level language features. It was developed by Bjarne Stroustrup starting in 1979 at Bell...

, and its source code is freely available.

Features

• Parsing speed (including DOM tree building) approaching speed of strlen function executed on the same data. On a modern CPU (as of 2008) the parser throughput is about 1 billion characters per second. See Performance section in the Online Manual.
• Small memory footprint of the code and created DOM trees.
• Configurable memory allocation.
• A headers-only implementation, simplifying the integration process.
• Simple license that allows use for almost any purpose, both commercial and non-commercial, without any obligations.
• Supports UTF-8
  UTF-8
  UTF-8 is a multibyte character encoding for Unicode. Like UTF-16 and UTF-32, UTF-8 can represent every character in the Unicode character set. Unlike them, it is backward-compatible with ASCII and avoids the complications of endianness and byte order marks...
  
   and partially UTF-16, UTF-32 encodings.
• Portable source code with no dependencies other than a very small subset of C++ Standard Library
  C++ standard library
  In C++, the C++ Standard Library is a collection of classes and functions, which are written in the core language and part of the C++ ISO Standard itself...
  
  . This subset is so small that it can be easily emulated manually if use of standard library is undesired.

Limitations

• The parser ignores DOCTYPE declarations.
• There is no support for XML namespaces.
• The parser does not check for character validity.
• The interface of the parser does not conform to DOM specification.
• The parser does not check for attribute uniqueness.

Applications

• Primary XML parser for Boost.PropertyTree library
