-pugixml 1.11 - an XML processing library
-
-Copyright (C) 2006-2020, by Arseny Kapoulkine (arseny.kapoulkine@gmail.com)
-Report bugs and download new versions at https://pugixml.org/
-
-This is the distribution of pugixml, which 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).
-
-The distribution contains the following folders:
-
- docs/ - documentation
- docs/samples - pugixml usage examples
- docs/quickstart.html - quick start guide
- docs/manual.html - complete manual
-
- scripts/ - project files for IDE/build systems
-
- src/ - header and source files
