Represents a node in the tree. Nodes are never encountered except as superclasses of other objects. Nodes have siblings.
Visit all subnodes of self recursively
# File lib/rexml/node.rb, line 53
53: def each_recursive(&block) # :yields: node
54: self.elements.each {|node|
55: block.call(node)
56: node.each_recursive(&block)
57: }
58: end
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.
