Nokogiri is an open source software library to parse HTML and XML in Ruby.

[3][4][5][6] It depends on libxml2 and libxslt to provide its functionality.

[7] It markets itself as providing a sensible, easy-to-understand API for reading, writing, modifying, and querying documents.

It provides fast and standards-compliant parser by relying on native parsers like libxml2 (CRuby) and xerces (JRuby).

[8] Enterprise support is available through tidelift,[9] a paid subscription model, offering commercial support for open source applications.
