About

libxml2 is a widely used C library implementing many XML-related standards like

  • XML 1.0 parser
    • push, pull, reader modes
    • event-based or DOM builder
  • DOM API
  • DTD validation
  • HTML 4 parser
  • XPath 1.0
  • XPointer 1.0
  • XInclude 1.0
  • XML Schema 1.0
  • Canonical XML 1.0
  • XML Catalogs
  • RelaxNG
  • Schematron

Prominent users include

  • KHTML/WebKit-derived web browsers like
    • Google Chrome
    • Microsoft Edge
    • Apple Safari 
  • Programming language bindings
    • PHP (core)
    • lxml (Python)
    • Nokogiri (Ruby)
    • XML::LibXML (Perl)
    • many others
  • Apache httpd
  • LibreOffice / OpenOffice
  • PostgreSQL 
  • Inkscape
  • ImageMagick
  • BIND DNS
  • Wine
  • more than 500 Debian packages

libxml2 is preinstalled on most UNIX-based systems like Linux, Android, iOS, macOS, ChromeOS. It is also used in Microsoft's Edge browser and consequently runs on the majority of all mobile devices, desktops and servers in the world. That said, most of the implemented standards from around 2000-2005 are considered legacy technology today and rarely used in new projects.

The project was started in 1998. Originally authored by Daniel Veillard, libxml2 received contributions from many parties in the early 2000s. After XML technologies largely fell out of favor, the pace of development decreased. In the early 2010s, the project was only lightly maintained. Since around 2015, Nick Wellnhofer contributed many bug fixes and improvements and gradually became maintainer of the project.
