What is RapidXml?</h2><para><a href="http://rapidxml.sourceforge.net">RapidXml</a> is an attempt to create the fastest XML DOM parser possible, while retaining useability, portability and reasonable W3C compatibility. It is an in-situ parser written in C++, with parsing speed approaching that of <code>strlen()</code> function executed on the same data. <br/><br/>

89

Entire parser is contained in a single header file, so no building or linking is neccesary. To use it you just need to copy <code>rapidxml.hpp</code> file to a convenient place (such as your project directory), and include it where needed. You may also want to use printing functions contained in header <code>rapidxml_print.hpp</code>.</para><sect2><h3 id="namespacerapidxml_1dependencies_and_compatibility">1.1 Dependencies And Compatibility</h3><para>RapidXml has <i>no dependencies</i> other than a very small subset of standard C++ library (<code><cassert></code>, <code><cstdlib></code>, <code><new></code> and <code><exception></code>, unless exceptions are disabled). It should compile on any reasonably conformant compiler, and was tested on Visual C++ 2003, Visual C++ 2005, Visual C++ 2008, gcc 3, gcc 4, and Comeau 4.3.3. Care was taken that no warnings are produced on these compilers, even with highest warning levels enabled.</para></sect2><sect2><h3 id="namespacerapidxml_1character_types_and_encodings">1.2 Character Types And Encodings</h3><para>RapidXml is character type agnostic, and can work both with narrow and wide characters. Current version does not fully support UTF-16 or UTF-32, so use of wide characters is somewhat incapacitated. However, it should succesfully parse <code>wchar_t</code> strings containing UTF-16 or UTF-32 if endianness of the data matches that of the machine. UTF-8 is fully supported, including all numeric character references, which are expanded into appropriate UTF-8 byte sequences (unless you enable parse_no_utf8 flag). <br/><br/>

90

Note that RapidXml performs no decoding - strings returned by name() and value() functions will contain text encoded using the same encoding as source file. Rapidxml understands and expands the following character references: <code>&apos; &amp; &quot; &lt; &gt; &#...;</code> Other character references are not expanded.</para></sect2><sect2><h3 id="namespacerapidxml_1error_handling">1.3 Error Handling</h3><para>By default, RapidXml uses C++ exceptions to report errors. If this behaviour is undesirable, RAPIDXML_NO_EXCEPTIONS can be defined to suppress exception code. See <a href="#classrapidxml_1_1parse__error" kindref="compound">parse_error</a> class and <a href="#namespacerapidxml_ff5d67f74437199d316d2b2660653ae1_1ff5d67f74437199d316d2b2660653ae1" kindref="member">parse_error_handler()</a> function for more information.</para></sect2><sect2><h3 id="namespacerapidxml_1memory_allocation">1.4 Memory Allocation</h3><para>RapidXml uses a special memory pool object to allocate nodes and attributes, because direct allocation using <code>new</code> operator would be far too slow. Underlying memory allocations performed by the pool can be customized by use of <a href="#classrapidxml_1_1memory__pool_c0a55a6ef0837dca67572e357100d78a_1c0a55a6ef0837dca67572e357100d78a" kindref="member">memory_pool::set_allocator()</a> function. See class <a href="#classrapidxml_1_1memory__pool" kindref="compound">memory_pool</a> for more information.</para></sect2><sect2><h3 id="namespacerapidxml_1w3c_compliance">1.5 W3C Compliance</h3><para>RapidXml is not a W3C compliant parser, primarily because it ignores DOCTYPE declarations. There is a number of other, minor incompatibilities as well. Still, it can successfully parse and produce complete trees of all valid XML files in W3C conformance suite (over 1000 files specially designed to find flaws in XML processors). In destructive mode it performs whitespace normalization and character entity substitution for a small set of built-in entities.</para></sect2><sect2><h3 id="namespacerapidxml_1api_design">1.6 API Design</h3><para>RapidXml API is minimalistic, to reduce code size as much as possible, and facilitate use in embedded environments. Additional convenience functions are provided in separate headers: <code>rapidxml_utils.hpp</code> and <code><a href="#rapidxml__print_8hpp" kindref="compound">rapidxml_print.hpp</a></code>. Contents of these headers is not an essential part of the library, and is currently not documented (otherwise than with comments in code).</para></sect2><sect2><h3 id="namespacerapidxml_1reliability">1.7 Reliability</h3><para>RapidXml is very robust and comes with a large harness of unit tests. Special care has been taken to ensure stability of the parser no matter what source text is thrown at it. One of the unit tests produces 100,000 randomly corrupted variants of XML document, which (when uncorrupted) contains all constructs recognized by RapidXml. RapidXml passes this test when it correctly recognizes that errors have been introduced, and does not crash or loop indefinitely. <br/><br/>

91

Another unit test puts RapidXml head-to-head with another, well estabilished XML parser, and verifies that their outputs match across a wide variety of small and large documents. <br/><br/>

92

Yet another test feeds RapidXml with over 1000 test files from W3C compliance suite, and verifies that correct results are obtained. There are also additional tests that verify each API function separately, and test that various parsing modes work as expected.</para></sect2><sect2><h3 id="namespacerapidxml_1acknowledgements">1.8 Acknowledgements</h3><para>I would like to thank Arseny Kapoulkine for his work on <a href="http://code.google.com/p/pugixml">pugixml</a>, which was an inspiration for this project. Additional thanks go to Kristen Wegner for creating <a href="http://www.codeproject.com/soap/pugxml.asp">pugxml</a>, from which pugixml was derived. Janusz Wohlfeil kindly ran RapidXml speed tests on hardware that I did not have access to, allowing me to expand performance comparison table.</para></sect2></sect1><sect1><h2 id="namespacerapidxml_1two_minute_tutorial">2. Two Minute Tutorial</h2><sect2><h3 id="namespacerapidxml_1parsing">2.1 Parsing</h3><para>The following code causes RapidXml to parse a zero-terminated string named <code>text</code>: <pre>using namespace rapidxml;

93

xml_document<> doc; // character type defaults to char

94

doc.parse<0>(text); // 0 means default parse flags

95

</pre><code>doc</code> object is now a root of DOM tree containing representation of the parsed XML. Because all RapidXml interface is contained inside namespace <code>rapidxml</code>, users must either bring contents of this namespace into scope, or fully qualify all the names. Class <a href="#classrapidxml_1_1xml__document" kindref="compound">xml_document</a> represents a root of the DOM hierarchy. By means of public inheritance, it is also an <a href="#classrapidxml_1_1xml__node" kindref="compound">xml_node</a> and a <a href="#classrapidxml_1_1memory__pool" kindref="compound">memory_pool</a>. Template parameter of <a href="#classrapidxml_1_1xml__document_8338ce6042e7b04d5a42144fb446b69c_18338ce6042e7b04d5a42144fb446b69c" kindref="member">xml_document::parse()</a> function is used to specify parsing flags, with which you can fine-tune behaviour of the parser. Note that flags must be a compile-time constant.</para></sect2><sect2><h3 id="namespacerapidxml_1accessing_dom_tree">2.2 Accessing The DOM Tree</h3><para>To access the DOM tree, use methods of <a href="#classrapidxml_1_1xml__node" kindref="compound">xml_node</a> and <a href="#classrapidxml_1_1xml__attribute" kindref="compound">xml_attribute</a> classes: <pre>cout << "Name of my first node is: " << doc.first_node()->name() << "\n";

96

xml_node<> *node = doc.first_node("foobar");

97

cout << "Node foobar has value " << node->value() << "\n";

98

for (xml_attribute<> *attr = node->first_attribute();

99

attr; attr = attr->next_attribute())

100

{

101

cout << "Node foobar has attribute " << attr->name() << " ";

102

cout << "with value " << attr->value() << "\n";

103

}

104

</pre></para></sect2><sect2><h3 id="namespacerapidxml_1modifying_dom_tree">2.3 Modifying The DOM Tree</h3><para>DOM tree produced by the parser is fully modifiable. Nodes and attributes can be added/removed, and their contents changed. The below example creates a HTML document, whose sole contents is a link to google.com website: <pre>xml_document<> doc;

105

xml_node<> *node = doc.allocate_node(node_element, "a", "Google");

106

doc.append_node(node);

107

xml_attribute<> *attr = doc.allocate_attribute("href", "google.com");

108

node->append_attribute(attr);

109

</pre> One quirk is that nodes and attributes <i>do not own</i> the text of their names and values. This is because normally they only store pointers to the source text. So, when assigning a new name or value to the node, care must be taken to ensure proper lifetime of the string. The easiest way to achieve it is to allocate the string from the <a href="#classrapidxml_1_1xml__document" kindref="compound">xml_document</a> memory pool. In the above example this is not necessary, because we are only assigning character constants. But the code below uses <a href="#classrapidxml_1_1memory__pool_69729185bc59b0875192d667c47b8859_169729185bc59b0875192d667c47b8859" kindref="member">memory_pool::allocate_string()</a> function to allocate node name (which will have the same lifetime as the document), and assigns it to a new node: <pre>xml_document<> doc;

110

char *node_name = doc.allocate_string(name); // Allocate string and copy name into it

111

xml_node<> *node = doc.allocate_node(node_element, node_name); // Set node name to node_name

</pre></para></sect2></sect1><sect1><h2 id="namespacerapidxml_1differences">3. Differences From Regular XML Parsers</h2><para>RapidXml is an <i>in-situ parser</i>, which allows it to achieve very high parsing speed. In-situ means that parser does not make copies of strings. Instead, it places pointers to the <i>source text</i> in the DOM hierarchy.</para><sect2><h3 id="namespacerapidxml_1lifetime_of_source_text">3.1 Lifetime Of Source Text</h3><para>In-situ parsing requires that source text lives at least as long as the document object. If source text is destroyed, names and values of nodes in DOM tree will become destroyed as well. Additionally, whitespace processing, character entity translation, and zero-termination of strings require that source text be modified during parsing (but see non-destructive mode). This makes the text useless for further processing once it was parsed by RapidXml. <br/><br/>

131

In many cases however, these are not serious issues.</para></sect2><sect2><h3 id="namespacerapidxml_1ownership_of_strings">3.2 Ownership Of Strings</h3><para>Nodes and attributes produced by RapidXml do not own their name and value strings. They merely hold the pointers to them. This means you have to be careful when setting these values manually, by using <a href="#classrapidxml_1_1xml__base_e099c291e104a0d277307fe71f5e0f9e_1e099c291e104a0d277307fe71f5e0f9e" kindref="member">xml_base::name(const Ch *)</a> or <a href="#classrapidxml_1_1xml__base_18c7469acdca771de9b4f3054053029c_118c7469acdca771de9b4f3054053029c" kindref="member">xml_base::value(const Ch *)</a> functions. Care must be taken to ensure that lifetime of the string passed is at least as long as lifetime of the node/attribute. The easiest way to achieve it is to allocate the string from <a href="#classrapidxml_1_1memory__pool" kindref="compound">memory_pool</a> owned by the document. Use <a href="#classrapidxml_1_1memory__pool_69729185bc59b0875192d667c47b8859_169729185bc59b0875192d667c47b8859" kindref="member">memory_pool::allocate_string()</a> function for this purpose.</para></sect2><sect2><h3 id="namespacerapidxml_1destructive_non_destructive">3.3 Destructive Vs Non-Destructive Mode</h3><para>By default, the parser modifies source text during the parsing process. This is required to achieve character entity translation, whitespace normalization, and zero-termination of strings. <br/><br/>

132

In some cases this behaviour may be undesirable, for example if source text resides in read only memory, or is mapped to memory directly from file. By using appropriate parser flags (parse_non_destructive), source text modifications can be disabled. However, because RapidXml does in-situ parsing, it obviously has the following side-effects:<ul><li><para>no whitespace normalization is done</para></li><li><para>no entity reference translation is done</para></li><li><para>names and values are not zero-terminated, you must use <a href="#classrapidxml_1_1xml__base_0dae694c8f7e4d89f1003e2f3a15a43c_10dae694c8f7e4d89f1003e2f3a15a43c" kindref="member">xml_base::name_size()</a> and <a href="#classrapidxml_1_1xml__base_aed5ae791b7164c1ee5e649198cbb3db_1aed5ae791b7164c1ee5e649198cbb3db" kindref="member">xml_base::value_size()</a> functions to tell where they end</para></li></ul></para></sect2></sect1><sect1><h2 id="namespacerapidxml_1performance">4.

As a rule of thumb, parsing speed is about 50-100x faster than Xerces DOM, 30-60x faster than TinyXml, 3-12x faster than pugxml, and about 5% - 30% faster than pugixml, the fastest XML parser I know of.</para><para><ul><li><para>The test file is a real-world, 50kB large, moderately dense XML file. </para></li><li><para>All timing is done by using RDTSC instruction present in Pentium-compatible CPUs. </para></li><li><para>No profile-guided optimizations are used. </para></li><li><para>All parsers are running in their fastest modes. </para></li><li><para>The results are given in CPU cycles per character, so frequency of CPUs is irrelevant. </para></li><li><para>The results are minimum values from a large number of runs, to minimize effects of operating system activity, task switching, interrupt handling etc. </para></li><li><para>A single parse of the test file takes about 1/10th of a millisecond, so with large number of runs there is a good chance of hitting at least one no-interrupt streak, and obtaining undisturbed results. </para></li></ul><table rows="9" cols="7" border="1" cellpadding="3pt"><tr><th thead="yes"><para><center>Platform</center></para></th><th thead="yes"><para><center>Compiler</center></para></th><th thead="yes"><para>strlen() </para></th><th thead="yes"><para>RapidXml </para></th><th thead="yes"><para>pugixml 0.3 </para></th><th thead="yes"><para>pugxml </para></th><th thead="yes"><para>TinyXml </para></th></tr><tr><td thead="no"><para><center>Pentium 4</center></para></td><td thead="no"><para><center>MSVC 8.0</center></para></td><td thead="no"><para><center>2.5</center></para></td><td thead="no"><para><center>5.4</center></para></td><td thead="no"><para><center>7.0</center></para></td><td thead="no"><para><center>61.7</center></para></td><td thead="no"><para><center>298.8</center></para></td></tr><tr><td thead="no"><para><center>Pentium 4</center></para></td><td thead="no"><para><center>gcc 4.1.1</center></para></td><td thead="no"><para><center>0.8</center></para></td><td thead="no"><para><center>6.1</center></para></td><td thead="no"><para><center>9.5</center></para></td><td thead="no"><para><center>67.0</center></para></td><td thead="no"><para><center>413.2</center></para></td></tr><tr><td thead="no"><para><center>Core 2</center></para></td><td thead="no"><para><center>MSVC 8.0</center></para></td><td thead="no"><para><center>1.0</center></para></td><td thead="no"><para><center>4.5</center></para></td><td thead="no"><para><center>5.0</center></para></td><td thead="no"><para><center>24.6</center></para></td><td thead="no"><para><center>154.8</center></para></td></tr><tr><td thead="no"><para><center>Core 2</center></para></td><td thead="no"><para><center>gcc 4.1.1</center></para></td><td thead="no"><para><center>0.6</center></para></td><td thead="no"><para><center>4.6</center></para></td><td thead="no"><para><center>5.4</center></para></td><td thead="no"><para><center>28.3</center></para></td><td thead="no"><para><center>229.3</center></para></td></tr><tr><td thead="no"><para><center>Athlon XP</center></para></td><td thead="no"><para><center>MSVC 8.0</center></para></td><td thead="no"><para><center>3.1</center></para></td><td thead="no"><para><center>7.7</center></para></td><td thead="no"><para><center>8.0</center></para></td><td thead="no"><para><center>25.5</center></para></td><td thead="no"><para><center>182.6</center></para></td></tr><tr><td thead="no"><para><center>Athlon XP</center></para></td><td thead="no"><para><center>gcc 4.1.1</center></para></td><td thead="no"><para><center>0.9</center></para></td><td thead="no"><para><center>8.2</center></para></td><td thead="no"><para><center>9.2</center></para></td><td thead="no"><para><center>33.7</center></para></td><td thead="no"><para><center>265.2</center></para></td></tr><tr><td thead="no"><para><center>Pentium 3</center></para></td><td thead="no"><para><center>MSVC 8.0</center></para></td><td thead="no"><para><center>2.0</center></para></td><td thead="no"><para><center>6.3</center></para></td><td thead="no"><para><center>7.0</center></para></td><td thead="no"><para><center>30.9</center></para></td><td thead="no"><para><center>211.9</center></para></td></tr><tr><td thead="no"><para><center>Pentium 3</center></para></td><td thead="no"><para><center>gcc 4.1.1</center></para></td><td thead="no"><para><center>1.0</center></para></td><td thead="no"><para><center>6.7</center></para></td><td thead="no"><para><center>8.9</center></para></td><td thead="no"><para><center>35.3</center></para></td><td thead="no"><para><center>316.0</center></para></td></tr></table><i>(*) All results are in CPU cycles per character of source text</i></para></sect2></sect1><sect1><h2 id="namespacerapidxml_1reference">5.

Base class for

<a href="#classrapidxml_1_1xml__document">xml_document</a> <h4>Description</h4><para xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">This class is used by the parser to create new nodes and attributes, without overheads of dynamic memory allocation. In most cases, you will not need to use this class directly. However, if you need to create nodes manually or modify names/values of nodes, you are encouraged to use <a href="#classrapidxml_1_1memory__pool" kindref="compound">memory_pool</a> of relevant <a href="#classrapidxml_1_1xml__document" kindref="compound">xml_document</a> to allocate the memory. Not only is this faster than allocating them by using <code>new</code> operator, but also their lifetime will be tied to the lifetime of document, possibly simplyfing memory management. <br/><br/>

197

Call <a href="#classrapidxml_1_1memory__pool_750ba3c610b129ac057d817509d08f41_1750ba3c610b129ac057d817509d08f41" kindref="member">allocate_node()</a> or <a href="#classrapidxml_1_1memory__pool_462de142669e0ff649e8e615b82bf457_1462de142669e0ff649e8e615b82bf457" kindref="member">allocate_attribute()</a> functions to obtain new nodes or attributes from the pool. You can also call <a href="#classrapidxml_1_1memory__pool_69729185bc59b0875192d667c47b8859_169729185bc59b0875192d667c47b8859" kindref="member">allocate_string()</a> function to allocate strings. Such strings can then be used as names or values of nodes without worrying about their lifetime. Note that there is no <code>free()</code> function -- all allocations are freed at once when <a href="#classrapidxml_1_1memory__pool_c8bb3912a3ce86b15842e79d0b421204_1c8bb3912a3ce86b15842e79d0b421204" kindref="member">clear()</a> function is called, or when the pool is destroyed. <br/><br/>

198

It is also possible to create a standalone <a href="#classrapidxml_1_1memory__pool" kindref="compound">memory_pool</a>, and use it to allocate nodes, whose lifetime will not be tied to any document. <br/><br/>

199

Pool maintains <code>RAPIDXML_STATIC_POOL_SIZE</code> bytes of statically allocated memory. Until static memory is exhausted, no dynamic memory allocations are done. When static memory is exhausted, pool allocates additional blocks of memory of size <code>RAPIDXML_DYNAMIC_POOL_SIZE</code> each, by using global <code>new[]</code> and <code>delete[]</code> operators. This behaviour can be changed by setting custom allocation routines. Use <a href="#classrapidxml_1_1memory__pool_c0a55a6ef0837dca67572e357100d78a_1c0a55a6ef0837dca67572e357100d78a" kindref="member">set_allocator()</a> function to set them. <br/><br/>

200

Allocations for nodes, attributes and strings are aligned at <code>RAPIDXML_ALIGNMENT</code> bytes. This value defaults to the size of pointer on target architecture. <br/><br/>

201

To obtain absolutely top performance from the parser, it is important that all nodes are allocated from a single, contiguous block of memory. Otherwise, cache misses when jumping between two (or more) disjoint blocks of memory can slow down parsing quite considerably. If required, you can tweak <code>RAPIDXML_STATIC_POOL_SIZE</code>, <code>RAPIDXML_DYNAMIC_POOL_SIZE</code> and <code>RAPIDXML_ALIGNMENT</code> to obtain best wasted memory to performance compromise. To do it, define their values before <a href="#rapidxml_8hpp" kindref="compound">rapidxml.hpp</a> file is included. </para><h4>Parameters</h4><dl><dt class="parameter-name">Ch</dt><dd>Character type of created nodes. </dd></dl><p/><h3 class="reference-header" id="classrapidxml_1_1memory__pool_f8fb3c8f1a564f8045c40bcd07a89866_1f8fb3c8f1a564f8045c40bcd07a89866">
