base on Light-weight, simple and fast XML parser for C++ with XPath support pugixml [](https://github.com/zeux/pugixml/actions) [](https://ci.appveyor.com/project/zeux/pugixml) [](https://codecov.io/github/zeux/pugixml?branch=master)  ======= 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 Documentation for the current release of pugixml is available on-line as two separate documents: * [Quick-start guide](https://pugixml.org/docs/quickstart.html), that aims to provide enough information to start using the library; * [Complete reference manual](https://pugixml.org/docs/manual.html), 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. ## Example 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: ```c++ #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: ```c++ #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"; } } ``` ## License This library is available to anybody free of charge, under the terms of MIT License (see LICENSE.md).
