Defined in:

#add_element(element, attrs = nil) ⇒ Object

:call-seq:

add_element(name, attributes = nil) -> new_element
add_element(element, attributes = nil) -> element

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

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

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

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

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

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

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

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

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