DOMAttr
class refers to an attribute of an XML element.
Typically the allowable values for the attribute are defined in a documenttype definition.
DOMAttr
objects inherit the DOMNode
interface, but since attributes are not actually child nodes of the elements they are associated with, the DOM does not consider them part of the document tree. Thus, the DOMNode
attributes parentNode
, previousSibling
, and nextSibling
have a null value for DOMAttr
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, attribute nodes may not be immediate children of a DOMDocumentFragment
. However, they can be associated with DOMElement
nodes contained within a DOMDocumentFragment
. In short, users of the DOM need to be aware that DOMAttr
nodes have some things in common with other objects inheriting the DOMNode
interface, but they also are quite distinct.

Returns true if the attribute received its value explicitly in the XML document, or if a value was assigned programatically with the setValue function. Returns false if the attribute value came from the default value declared in the document's DTD.

Returns the type information associated with this attribute. "Experimental - subject to change"
|
|
Returns the value of the attribute. The value of the attribute is returned as a string. Character and general entity references are replaced with their values.
|
|
Returns whether this attribute is known to be of type ID or not. When it is and its value is unique, the ownerElement of this attribute can be retrieved using getElementById on Document. "Experimental - subject to change"
|
|
Sets the value of the attribute. A text node with the unparsed contents of the string will be created.
