NAME
    XML::DOM::Attr - An XML attribute in XML::DOM

DESCRIPTION
    XML::DOM::Attr extends XML::DOM::Node.

    The Attr nodes built by the XML::DOM::Parser always have one child node
    which is a Text node containing the expanded string value (i.e.
    EntityReferences are always expanded.) EntityReferences may be added
    when modifying or creating a new Document.

    The Attr interface represents an attribute in an Element object.
    Typically the allowable values for the attribute are defined in a
    document type definition.

    Attr objects inherit the Node interface, but since they are not actually
    child nodes of the element they describe, the DOM does not consider them
    part of the document tree. Thus, the Node attributes parentNode,
    previousSibling, and nextSibling have a undef value for Attr objects.
    The DOM takes the view that attributes are properties of elements rather
    than having a separate identity from the elements they are associated
    with; this should make it more efficient to implement such features as
    default attributes associated with all elements of a given type.
    Furthermore, Attr nodes may not be immediate children of a
    DocumentFragment. However, they can be associated with Element nodes
    contained within a DocumentFragment. In short, users and implementors of
    the DOM need to be aware that Attr nodes have some things in common with
    other objects inheriting the Node interface, but they also are quite
    distinct.

    The attribute's effective value is determined as follows: if this
    attribute has been explicitly assigned any value, that value is the
    attribute's effective value; otherwise, if there is a declaration for
    this attribute, and that declaration includes a default value, then that
    default value is the attribute's effective value; otherwise, the
    attribute does not exist on this element in the structure model until it
    has been explicitly added. Note that the nodeValue attribute on the Attr
    instance can also be used to retrieve the string version of the
    attribute's value(s).

    In XML, where the value of an attribute can contain entity references,
    the child nodes of the Attr node provide a representation in which
    entity references are not expanded. These child nodes may be either Text
    or EntityReference nodes. Because the attribute type may be unknown,
    there are no tokenized attribute values.

  METHODS
    getValue
        On retrieval, the value of the attribute is returned as a string.
        Character and general entity references are replaced with their
        values.

    setValue (str)
        DOM Spec: On setting, this creates a Text node with the unparsed
        contents of the string.

    getName
        Returns the name of this attribute.
