The Ruby has many APIs for parsing & generating XML. The  REXML is the standard API that ships as part of the Ruby core, whereas the frameworks like Builder & Hpricot are available as gems. The Gems are essentially third-party APIs or the libraries that conform to an specific format. They are easily downloadable & installable (conceptually similar to an third-party Java API available in an JAR file).

The REXML is the standard Ruby library for parsing & creating the XML. It is bundled as part of the Ruby Core language distribution, so you know it will always be available.

It is lightweight,  less than 2000 lines of code. The methods & classes are really easy-to-understand. The SAX2-based API & Full XPath support.  Shipped with Ruby installation & no separate installation is required.
