REXML::Element#add_attribute

Adds an attribute to this element, overwriting any existing attribute by the same name.

key: can be either an Attribute or a String. If an Attribute, the attribute is added to the list of Element attributes. If String, the argument is used as the name of the new attribute, and the value parameter must be supplied.
value: Required if key is a String, and ignored if the first argument is an Attribute. This is a String, and is used as the value of the new Attribute. This should be the unnormalized value of the attribute (without entities).
Returns: the Attribute added

e = Element.new 'e'
e.add_attribute( 'a', 'b' )               #-> <e a='b'/>
e.add_attribute( 'x:a', 'c' )             #-> <e a='b' x:a='c'/>
e.add_attribute Attribute.new('b', 'd')   #-> <e a='b' x:a='c' b='d'/>

REXML::Element#add_attributes

Add multiple attributes to this element.

hash: is either a hash, or array of arrays

el.add_attributes( {"name1"=>"value1", "name2"=>"value2"} )
el.add_attributes( [ ["name1","value1"], ["name2"=>"value2"] ] )

REXML::Element#delete_attribute

Removes an attribute

key: either an Attribute or a String. In either case, the attribute is found by matching the attribute name to the argument, and then removed. If no attribute is found, no action is taken.
Returns: the attribute removed, or nil if this Element did not contain a matching attribute

e = Element.new('E')
e.add_attribute( 'name', 'Sean' )             #-> <E name='Sean'/>
r = e.add_attribute( 'sur:name', 'Russell' )  #-> <E name='Sean' sur:name='Russell'/>
e.delete_attribute( 'name' )                  #-> <E sur:name='Russell'/>
e.delete_attribute( r )                       #-> <E/>

REXML::Attributes#each_attribute

Iterates over the attributes of an Element. Yields actual Attribute nodes, not String values.

doc = Document.new '<a x="1" y="2"/>'
doc.root.attributes.each_attribute {|attr|
  p attr.expanded_name+" => "+attr.value
}

REXML::Attributes#get_attribute

Fetches an attribute

name: the name by which to search for the attribute. Can be a prefix:name namespace name.
Returns: The first matching attribute, or nil if there was none. This

value is an Attribute node, not the String value of the attribute.

doc = Document.new '<a x:foo="1" foo="2" bar="3"/>'
doc.root.attributes.get_attribute("foo").value    #-> "2"
doc.root.attributes.get_attribute("x:foo").value  #-> "1"
