ruby-rexml 3.2.4-1 (s390x binary) in ubuntu groovy

 REXML was inspired by the Electric XML library for Java, which features an
 easy-to-use API, small size, and speed. Hopefully, REXML, designed with the
 same philosophy, has these same features. It supports both tree and stream
 document parsing. Stream parsing is faster (about 1.5 times as fast). However,
 with stream parsing, one doesn't get access to features such as XPath.

 Versions of this gem are also shipped with libruby2.x.
