class REXML::Element

def add_element element, attrs=nil


e0[1] # =>
e0.add_element(e1, {'bat' => '0', 'bam' => '1'})

sets attributes on the added element:
With argument +element+ and hash argument +attributes+,

e0[0] # =>
e0.add_element(e1)
e1 = REXML::Element.new('bar')
e0 = REXML::Element.new('foo')

With element argument +element+, adds that element as a child:

e0[1] # =>
e0.add_element('baz', {'bat' => '0', 'bam' => '1'})

sets attributes on the new element:
With argument +name+ and hash argument +attributes+,


e0[0] # =>
e0.add_element('bar')
e0 = REXML::Element.new('foo')

and adds the new element as a child:
With string argument +name+, creates a new element with that name

on the added element; returns the added element.
Adds a child element, optionally setting attributes
