# An \REXML::Element object represents an XML element.
#
# An element:
#
# - Has a name (string).
# - May have a parent (another element).
# - Has zero or more children
#   (other elements, text, CDATA, processing instructions, and comments).
# - Has zero or more siblings
#   (other elements, text, CDATA, processing instructions, and comments).
# - Has zero or more named attributes.
#
# == In a Hurry?
#
# If you're somewhat familiar with XML
# and have a particular task in mind,
# you may want to see the
# {tasks pages}[../doc/rexml/tasks/tocs/master_toc_rdoc.html],
# and in particular, the
# {tasks page for elements}[../doc/rexml/tasks/tocs/element_toc_rdoc.html].
#
# === Name
#
# An element has a name, which is initially set when the element is created:
#
#   e = REXML::Element.new('foo')
#   e.name # => "foo"
#
# The name may be changed:
#
#   e.name = 'bar'
#   e.name # => "bar"
#
#
# === \Parent
#
# An element may have a parent.
#
# Its parent may be assigned explicitly when the element is created:
#
#   e0 = REXML::Element.new('foo')
#   e1 = REXML::Element.new('bar', e0)
#   e1.parent # => <foo> ... </>
#
# Note: the representation of an element always shows the element's name.
# If the element has children, the representation indicates that
# by including an ellipsis (<tt>...</tt>).
#
# The parent may be assigned explicitly at any time:
#
#   e2 = REXML::Element.new('baz')
#   e1.parent = e2
#   e1.parent # => <baz/>
#
# When an element is added as a child, its parent is set automatically:
#
#   e1.add_element(e0)
#   e0.parent # => <bar> ... </>
#
# For an element that has no parent, method +parent+ returns +nil+.
#
# === Children
#
# An element has zero or more children.
# The children are an ordered collection
# of all objects whose parent is the element itself.
#
# The children may include any combination of elements, text, comments,
# processing instructions, and CDATA.
# (This example keeps things clean by controlling whitespace
# via a +context+ setting.)

#    root = d.root
#    root.children.size # => 10
#    root.each {|child| p "#{child.class}: #{child}" }
#
# Output:

#   "REXML::Comment: comment 1"
#   "REXML::Instruction: <?target_0 pi_1?>"
#   "REXML::CData: cdata 1"
#
# A child may be added using inherited methods
# Parent#insert_before or Parent#insert_after:
#
#   xml_string = '<root><a/><c/><d/></root>'
#   d = REXML::Document.new(xml_string)
#   root = d.root
#   c = d.root[1] # => <c/>
#   root.insert_before(c, REXML::Element.new('b'))
#   root.to_a # => [<a/>, <b/>, <c/>, <d/>]
#
# A child may be replaced using Parent#replace_child:
#
#   root.replace_child(c, REXML::Element.new('x'))
#   root.to_a # => [<a/>, <b/>, <x/>, <d/>]
#
# A child may be removed using Parent#delete:
#
#   x = root[2] # => <x/>
#   root.delete(x)
#   root.to_a # => [<a/>, <b/>, <d/>]
#
# === Siblings
#
# An element has zero or more siblings,
# which are the other children of the element's parent.
#
# In the example above, element +ele_1+ is between a CDATA sibling
# and a text sibling:
#
#   ele_1 = root[5]        # => <ele_1/>
#   ele_1.previous_sibling # => "cdata 0"
#   ele_1.next_sibling     # => "\n text 1\n "
#
# === \Attributes
#
# An element has zero or more named attributes.
#
# A new element has no attributes:
#
#   e = REXML::Element.new('foo')
#   e.attributes      # => {}
#
# Attributes may be added:
#
#   e.add_attribute('bar', 'baz')
#   e.add_attribute('bat', 'bam')
#   e.attributes.size # => 2
#   e['bar']          # => "baz"
#   e['bat']          # => "bam"
#
# An existing attribute may be modified:
#
#   e.add_attribute('bar', 'bad')
#   e.attributes.size # => 2
#   e['bar']          # => "bad"
#
# An existing attribute may be deleted:
#
#   e.delete_attribute('bar')
#   e.attributes.size # => 1
#   e['bar']          # => nil
#
