Public Instance methods
prefix()

Returns the namespace of the attribute.

 e = Element.new( "elns:myelement" )
 e.add_attribute( "nsa:a", "aval" )
 e.add_attribute( "b", "bval" )
 e.attributes.get_attribute( "a" ).prefix   # -> "nsa"
 e.attributes.get_attribute( "b" ).prefix   # -> "elns"
 a = Attribute.new( "x", "y" )
 a.prefix                                   # -> ""
namespace(arg=nil)

Returns the namespace URL, if defined, or nil otherwise

 e = Element.new("el")

==( other )

Returns true if other is an Attribute and has the same name and value, false otherwise.

hash()

to_string()

Returns this attribute out as XML source, expanding the name

 a = Attribute.new( "x", "y" )
 a.to_string     # -> "x='y'"
 b = Attribute.new( "ns:x", "y" )
 b.to_string     # -> "ns:x='y'"
to_s()

Returns the attribute value, normalized

value()
