Public Instance Methods

each_recursive() click to toggle source

Visit all subnodes of self recursively

 
               # File rexml-3.2.5/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() click to toggle source

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

 
               # File rexml-3.2.5/lib/rexml/node.rb, line 63
def find_first_recursive(&block) # :yields: node
  each_recursive {|node|
    return node if block.call(node)
  }
  return nil

                    to << indentstyle*ind unless ind<1
end
index_in_parent() click to toggle source

def index_in_parent
  parent.index(self)+1
end

@return the next sibling (nil if unset)

 
               # File rexml-3.2.5/lib/rexml/node.rb, line 11
def next_sibling_node
  return nil if @parent.nil?
  @parent[ @parent.index(self) + 1 ]
end

@return the previous sibling (nil if unset)

 
               # File rexml-3.2.5/lib/rexml/node.rb, line 17
def previous_sibling_node
  return nil if @parent.nil?
  ind = @parent.index(self)
  return nil if ind == 0
