<div class="paragraph">
<p><a href="http://pugixml.org/">pugixml</a> is a light-weight C++ XML processing library. It 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 <a href="#xpath">XPath 1.0 implementation</a> for complex data-driven tree queries. Full Unicode support is also available, with <a href="#dom.unicode">two Unicode interface variants</a> and conversions between different Unicode encodings (which happen automatically during parsing/saving). The library is <a href="#install.portability">extremely portable</a> and easy to integrate and use. pugixml is developed and maintained since 2006 and has many users. All code is distributed under the <a href="#overview.license">MIT license</a>, making it completely free to use in both open-source and proprietary applications.</p>
</div>
<div class="paragraph">
<p>pugixml enables very fast, convenient and memory-efficient XML document processing. However, since pugixml has a DOM parser, it can’t process XML documents that do not fit in memory; also the parser is a non-validating one, so if you need DTD or XML Schema validation, the library is not for you.</p>
</div>
<div class="paragraph">
<p>This is the complete manual for pugixml, which describes all features of the library in detail. If you want to start writing code as quickly as possible, you are advised to <a href="quickstart.html">read the quick start guide first</a>.</p>

<div class="paragraph">
<p>If you believe you’ve found a bug in pugixml (bugs include compilation problems (errors/warnings), crashes, performance degradation and incorrect behavior), please file an issue via <a href="https://github.com/zeux/pugixml/issues/new">issue submission form</a>. Be sure to include the relevant information so that the bug can be reproduced: the version of pugixml, compiler version and target architecture, the code that uses pugixml and exhibits the bug, etc.</p>
</div>
<div class="paragraph">
<p>Feature requests can be reported the same way as bugs, so if you’re missing some functionality in pugixml or if the API is rough in some places and you can suggest an improvement, <a href="https://github.com/zeux/pugixml/issues/new">file an issue</a>. However please note that there are many factors when considering API changes (compatibility with previous versions, API redundancy, etc.), so generally features that can be implemented via a small function without pugixml modification are not accepted. However, all rules have exceptions.</p>
</div>
<div class="paragraph">
<p>If you have a contribution to pugixml, such as build script for some build system/IDE, or a well-designed set of helper functions, or a binding to some language other than C++, please <a href="https://github.com/zeux/pugixml/issues/new">file an issue or open a pull request</a>. Your contribution has to be distributed under the terms of a license that’s compatible with pugixml license; i.e. GPL/LGPL licensed code is not accepted.</p>

<div class="paragraph">
<p>If filing an issue is not possible due to privacy or other concerns, you can contact pugixml author by e-mail directly: <a href="mailto:arseny.kapoulkine@gmail.com">arseny.kapoulkine@gmail.com</a>.</p>

<div class="paragraph">
<p>pugixml is distributed in source form without any pre-built binaries; you have to build them yourself.</p>
</div>
<div class="paragraph">
<p>The complete pugixml source consists of three files - one source file, <code>pugixml.cpp</code>, and two header files, <code>pugixml.hpp</code> and <code>pugiconfig.hpp</code>. <code>pugixml.hpp</code> is the primary header which you need to include in order to use pugixml classes/functions; <code>pugiconfig.hpp</code> is a supplementary configuration file (see <a href="#install.building.config">Additional configuration options</a>). The rest of this guide assumes that <code>pugixml.hpp</code> is either in the current directory or in one of include directories of your projects, so that <code>#include "pugixml.hpp"</code> can find the header; however you can also use relative path (i.e. <code>#include "../libs/pugixml/src/pugixml.hpp"</code>) or include directory-relative path (i.e. <code>#include <xml/thirdparty/pugixml/src/pugixml.hpp></code>).</p>

<p>The easiest way to build pugixml is to compile the source file, <code>pugixml.cpp</code>, along with the existing library/executable. This process depends on the method of building your application; for example, if you’re using Microsoft Visual Studio <sup class="footnote">[<a id="_footnoteref_1" class="footnote" href="#_footnote_1" title="View footnote.">1</a>]</sup>, Apple Xcode, Code::Blocks or any other IDE, just add <code>pugixml.cpp</code> to one of your projects.</p>

<p>It’s possible to compile pugixml as a standalone static library. This process depends on the method of building your application; pugixml distribution comes with project files for several popular IDEs/build systems. There are project files for Apple XCode, Code::Blocks, Codelite, Microsoft Visual Studio 2005, 2008, 2010+, and configuration scripts for CMake and premake4. You’re welcome to submit project files/build scripts for other software; see <a href="#overview.feedback">Feedback</a>.</p>
</div>
<div class="paragraph">
<p>There are two projects for each version of Microsoft Visual Studio: one for dynamically linked CRT, which has a name like <code>pugixml_vs2008.vcproj</code>, and another one for statically linked CRT, which has a name like <code>pugixml_vs2008_static.vcproj</code>. You should select the version that matches the CRT used in your application; the default option for new projects created by Microsoft Visual Studio is dynamically linked CRT, so unless you changed the defaults, you should use the version with dynamic CRT (i.e. <code>pugixml_vs2008.vcproj</code> for Microsoft Visual Studio 2008).</p>
</div>
<div class="paragraph">
<p>In addition to adding pugixml project to your workspace, you’ll have to make sure that your application links with pugixml library. If you’re using Microsoft Visual Studio 2005/2008, you can add a dependency from your application project to pugixml one. If you’re using Microsoft Visual Studio 2010+, you’ll have to add a reference to your application project instead. For other IDEs/systems, consult the relevant documentation.</p>

<p>It’s possible to compile pugixml as a standalone shared library. The process is usually similar to the static library approach; however, no preconfigured projects/scripts are included into pugixml distribution, so you’ll have to do it yourself. Generally, if you’re using GCC-based toolchain, the process does not differ from building any other library as DLL (adding -shared to compilation flags should suffice); if you’re using MSVC-based toolchain, you’ll have to explicitly mark exported symbols with a declspec attribute. You can do it by defining <a href="#PUGIXML_API">PUGIXML_API</a> macro, i.e. via <code>pugiconfig.hpp</code>:</p>

If you’re using STL-related functions, you should use the shared runtime library to ensure that a single heap is used for STL allocations in your application and in pugixml; in MSVC, this means selecting the 'Multithreaded DLL' or 'Multithreaded Debug DLL' to 'Runtime library' property (<code>/MD</code> or <code>/MDd</code> linker switch). You should also make sure that your runtime library choice is consistent between different projects.

<div id="PUGIXML_HEADER_ONLY" class="paragraph">
<p>It’s possible to use pugixml in header-only mode. This means that all source code for pugixml will be included in every translation unit that includes <code>pugixml.hpp</code>. This is how most of Boost and STL libraries work.</p>
</div>
<div class="paragraph">
<p>Note that there are advantages and drawbacks of this approach. Header mode may improve tree traversal/modification performance (because many simple functions will be inlined), if your compiler toolchain does not support link-time optimization, or if you have it turned off (with link-time optimization the performance should be similar to non-header mode). However, since compiler now has to compile pugixml source once for each translation unit that includes it, compilation times may increase noticeably. If you want to use pugixml in header mode but do not need XPath support, you can consider disabling it by using <a href="#PUGIXML_NO_XPATH">PUGIXML_NO_XPATH</a> define to improve compilation time.</p>
</div>
<div class="paragraph">
<p>To enable header-only mode, you have to define <code>PUGIXML_HEADER_ONLY</code>. You can either do it in <code>pugiconfig.hpp</code>, or provide them via compiler command-line.</p>
</div>
<div class="paragraph">
<p>Note that it is safe to compile <code>pugixml.cpp</code> if <code>PUGIXML_HEADER_ONLY</code> is defined - so if you want to i.e. use header-only mode only in Release configuration, you
can include pugixml.cpp in your project (see <a href="#install.building.embed">Building pugixml as a part of another static library/executable</a>), and conditionally enable header-only mode in <code>pugiconfig.hpp</code> like this:</p>

<div class="paragraph">
<p>pugixml uses several defines to control the compilation process. There are two ways to define them: either put the needed definitions to <code>pugiconfig.hpp</code> (it has some examples that are commented out) or provide them via compiler command-line. Consistency is important: the definitions should match in all source files that include <code>pugixml.hpp</code> (including pugixml sources) throughout the application. Adding defines to <code>pugiconfig.hpp</code> lets you guarantee this, unless your macro definition is wrapped in preprocessor <code>#if</code>/<code>#ifdef</code> directive and this directive is not consistent. <code>pugiconfig.hpp</code> will never contain anything but comments, which means that when upgrading to a new version, you can safely leave your modified version intact.</p>

<div class="paragraph">
<p><a id="PUGIXML_WCHAR_MODE"></a><code>PUGIXML_WCHAR_MODE</code> define toggles between UTF-8 style interface (the in-memory text encoding is assumed to be UTF-8, most functions use <code>char</code> as character type) and UTF-16/32 style interface (the in-memory text encoding is assumed to be UTF-16/32, depending on <code>wchar_t</code> size, most functions use <code>wchar_t</code> as character type). See <a href="#dom.unicode">Unicode interface</a> for more details.</p>
</div>
<div class="paragraph">
<p><a id="PUGIXML_COMPACT"></a><code>PUGIXML_COMPACT</code> define activates a different internal representation of document storage that is much more memory efficient for documents with a lot of markup (i.e. nodes and attributes), but is slightly slower to parse and access. For details see <a href="#dom.memory.compact">Compact mode</a>.</p>
</div>
<div class="paragraph">
<p><a id="PUGIXML_NO_XPATH"></a><code>PUGIXML_NO_XPATH</code> define disables XPath. Both XPath interfaces and XPath implementation are excluded from compilation. This option is provided in case you do not need XPath functionality and need to save code space.</p>
</div>
<div class="paragraph">
<p><a id="PUGIXML_NO_STL"></a><code>PUGIXML_NO_STL</code> define disables use of STL in pugixml. The functions that operate on STL types are no longer present (i.e. load/save via iostream) if this macro is defined. This option is provided in case your target platform does not have a standard-compliant STL implementation.</p>
</div>
<div class="paragraph">
<p><a id="PUGIXML_NO_EXCEPTIONS"></a><code>PUGIXML_NO_EXCEPTIONS</code> define disables use of exceptions in pugixml. This option is provided in case your target platform does not have exception handling capabilities.</p>

<p><a id="PUGIXML_API"></a><code>PUGIXML_API</code>, <a id="PUGIXML_CLASS"></a><code>PUGIXML_CLASS</code> and <a id="PUGIXML_FUNCTION"></a><code>PUGIXML_FUNCTION</code> defines let you specify custom attributes (i.e. declspec or calling conventions) for pugixml classes and non-member functions. In absence of <code>PUGIXML_CLASS</code> or <code>PUGIXML_FUNCTION</code> definitions, <code>PUGIXML_API</code> definition is used instead. For example, to specify fixed calling convention, you can define <code>PUGIXML_FUNCTION</code> to i.e. <code>__fastcall</code>. Another example is DLL import/export attributes in MSVC (see <a href="#install.building.shared">Building pugixml as a standalone shared library</a>).</p>
