Public Instance Methods

each_recursive() click to toggle source

Visit all subnodes of self recursively

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

                    if @parent and @parent.context and not @parent.context[:indentstyle].nil? then
                            indentstyle = @parent.context[:indentstyle]
                    else
                            indentstyle = '  '
                    end
                    to << indentstyle*ind unless ind<1
end

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

 
               # File rexml/node.rb, line 72
def index_in_parent
  parent.index(self)+1
end
next_sibling_node() click to toggle source

@return the next sibling (nil if unset)

 
               # File rexml/node.rb, line 11
def next_sibling_node
  return nil if @parent.nil?
  @parent[ @parent.index(self) + 1 ]
end
parent?() click to toggle source 
 
               # File rexml/node.rb, line 48
def parent?
  false;
end
previous_sibling_node() click to toggle source

@return the previous sibling (nil if unset)

 
               # File rexml/node.rb, line 17
def previous_sibling_node
  return nil if @parent.nil?
  ind = @parent.index(self)
  return nil if ind == 0
  @parent[ ind - 1 ]

DEPRECATED This parameter is now ignored. See the formatters in the REXML::Formatters package for changing the output style.

  unless indent.nil?
    Kernel.warn( "#{self.class.name}.to_s(indent) parameter is deprecated" )
    f = REXML::Formatters::Pretty.new( indent )
    f.write( self, rv = "" )
  else
    f = REXML::Formatters::Default.new
