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 rexml/node.rb, line 53 def each_recursive(&block) # :yields: node self.elements.each {|node| block.call(node) node.each_recursive(&block) } end
Find (and return) first subnode (recursively) for which the block evaluates
to true. Returns nil
if none was found.
# File rexml/node.rb, line 62 def find_first_recursive(&block) # :yields: node each_recursive {|node| return node if block.call(node) } return nil end
# File rexml/node.rb, line 38 def indent to, ind 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 71 def index_in_parent parent.index(self)+1 end
@return the next sibling (nil if unset)
# File rexml/node.rb, line 10 def next_sibling_node return nil if @parent.nil? @parent[ @parent.index(self) + 1 ] end
@return the previous sibling (nil if unset)
# File rexml/node.rb, line 16 def previous_sibling_node return nil if @parent.nil? ind = @parent.index(self) return nil if ind == 0 @parent[ ind - 1 ] end
DEPRECATED This parameter is now ignored. See the formatters in the REXML::Formatters package for changing the output style.
