Visit all subnodes of self
recursively
# File rexml-3.2.8/lib/rexml/node.rb, line 54 def each_recursive(&block) # :yields: node self.elements.each {|node| block.call(node) node.each_recursive(&block) } end
find_first_recursive() { |node| ... }

Find (and return) first subnode (recursively) for which the block evaluates to true. Returns nil
if none was found.

Returns the position that self
holds in its parent’s array, indexed from 1.
