Handling Attributes in JDOM

• Most attribute work can be done through the Element class.

• Each attribute is represented as an Attribute object

• Each Attribute has:

  • A local name, a String

  • A value, a String

  • A Namespace object (which may be Namespace.NO_NAMESPACE)

  • A parent Element object (which may be null)

  • A type code such as Attribute.CDATA_ATTRIBUTE, Attribute.ID_ATTRIBUTE, or Attribute.UNDECLARED_ATTRIBUTE )

  Everything else can be determined from these five items.

• JDOM enforces restrictions on attribute names and values; e.g. value may not contain < or >

• Attributes are stored in a java.util.List in the Element that contains them

• This list only contains Attribute objects.
