Class Attributes

java.lang.Object
  org.jsoup.nodes.Attributes

All Implemented Interfaces:

Cloneable, Iterable<Attribute>

public class Attributes
extends Object
implements Iterable<Attribute>, Cloneable

The attributes of an Element.

Attributes are treated as a map: there can be only one value associated with an attribute key.

Attribute key and value comparisons are done case insensitively, and keys are normalised to lower-case.
