pugixml 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).
pugixml is used by a lot of projects, both open-source and proprietary, for performance and easy-to-use interface.
Documentation for the current release of pugixml is available on-line as two separate documents:
- Quick-start guide, that aims to provide enough information to start using the library;
- Complete reference manual, that describes all features of the library in detail.
You’re advised to start with the quick-start guide; however, many important library features are either not described in it at all or only mentioned briefly; if you require more information you should read the complete manual.
Here's an example of how code using pugixml looks; it opens an XML file, goes over all Tool nodes and prints tools that have a Timeout attribute greater than 0:
#include "pugixml.hpp"
#include <iostream>
int main()
{
pugi::xml_document doc;
pugi::xml_parse_result result = doc.load_file("xgconsole.xml");
if (!result)
return -1;
for (pugi::xml_node tool: doc.child("Profile").child("Tools").children("Tool"))
{
int timeout = tool.attribute("Timeout").as_int();
if (timeout > 0)
std::cout << "Tool " << tool.attribute("Filename").value() << " has timeout " << timeout << "\n";
}
}And the same example using XPath:
#include "pugixml.hpp"
#include <iostream>
int main()
{
pugi::xml_document doc;
pugi::xml_parse_result result = doc.load_file("xgconsole.xml");
if (!result)
return -1;
pugi::xpath_node_set tools_with_timeout = doc.select_nodes("/Profile/Tools/Tool[@Timeout > 0]");
for (pugi::xpath_node node: tools_with_timeout)
{
pugi::xml_node tool = node.node();
std::cout << "Tool " << tool.attribute("Filename").value() <<
" has timeout " << tool.attribute("Timeout").as_int() << "\n";
}
