 Attributes</Title>

 <Sect1> <Title><Anchor Id="SDK279"/>Introduction to Attributes

 </Title>

 <Para>Elements may have attributes associated with them; since the Element

 interface inherits from Node, the generic Node interface method 

 <Function>getAttributes</Function> may be used to retrieve the set of all

 attributes for an element. </Para>

 <Para>There are methods on the Element interface to retrieve either an Attr

 object by name or an attribute value by name. In XML, where an attribute value

 may contain entity references, an Attr object should be retrieved to examine

 the possibly fairly complex sub-tree representing the attribute value. On the

 other hand, in HTML, where all attributes have simple string values, methods to

 directly access an attribute value can safely be used as a convenience. </Para>

 <Para>Before you can access an Attribute, you must first gain access to the

 associated Element.</Para> </Sect1>

 <Sect1> <Title><Anchor Id="SDK378"/>Setting the Attribute

 Values</Title>

 <Para>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 null 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. </Para> 

 <Para>The attribute's effective value is determined as follows:</Para> 

 <ItemizedList Mark="Bullet"> <ListItem> 

 <Para>If this attribute has been explicitly assigned any value, that value is

 the attribute's effective value</Para></ListItem> <ListItem> 

 <Para>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</Para></ListItem> <ListItem> 

 <Para>Otherwise, the attribute does not exist on this element in the structure

 model until it has been explicitly added.</Para></ListItem> </ItemizedList> 

 <Para>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. </Para> 

 <Para>The following topics describe DOM attributes: </Para>

 <Para> <Function>setAttribute</Function> adds a new attribute. If an attribute

 with that name is already present in the element, its value is changed to be

 that of the value parameter. This value is a simple string, it is not parsed as

 it is being set. So any markup (such as syntax to be recognized as an entity

 reference) is treated as literal text, and needs to be appropriately escaped by

 the implementation when it is written out.</Para>

 <Para> In order to assign an attribute value that contains entity references,

 the user must create an Attr node plus any Text and EntityReference nodes,

 build the appropriate subtree, and use <Function>setAttributeNode</Function> to

 assign it as the value of an attribute. </Para> </RefSect1></RefEntry>
