Overview
Represents a node in the tree. Nodes are never encountered except as superclasses of other objects. Nodes have siblings.
Instance Attribute Summary
- #parent? ⇒ Boolean readonly
Instance Method Summary
-
#each_recursive(&block)
Visit all subnodes of
self
recursively. -
#find_first_recursive(&block)
Find (and return) first subnode (recursively) for which the block evaluates to true.
- #indent(to, ind)
-
#index_in_parent
Returns the position that
self
holds in its parent's array, indexed from 1. - #next_sibling_node ⇒ Object (also: #next_sibling)
- #previous_sibling_node ⇒ Object (also: #previous_sibling)
-
#to_s(indent = nil)
- indent

#each_recursive(&block)
Visit all subnodes of self
recursively
# File '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(&block)
Find (and return) first subnode (recursively) for which the block evaluates to true. Returns nil
if none was found.
# File 'lib/rexml/node.rb', line 63

#index_in_parent
Returns the position that self
holds in its parent's array, indexed from 1.
# File 'lib/rexml/node.rb', line 72
