Get immediate parent node in REXML

Question

How do I get the immediate parent of a node with REXML? root_node() gets me the parent node of the document, but I just want the parent of the current node.

Answer 1

require "rexml/document"

string = "
  <root>
    <a>
      <b>
        test
      </b>
    </a>
  </root>"

doc = REXML::Document.new string
p doc[1][1][1] #=> <b> ... </>
p doc[1][1][1].parent #=> <a> ... </>
