The <code><aclass="el"href="classxercesc_1_1DOMAttr.html"title="The DOMAttr class refers to an attribute of an XML element.">DOMAttr</a></code> class refers to an attribute of an XML element.
<code><aclass="el"href="classxercesc_1_1DOMAttr.html"title="The DOMAttr class refers to an attribute of an XML element.">DOMAttr</a></code> objects inherit the <code><aclass="el"href="classxercesc_1_1DOMNode.html"title="The DOMNode interface is the primary datatype for the entire Document Object Model...">DOMNode</a></code> 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 <code><aclass="el"href="classxercesc_1_1DOMNode.html"title="The DOMNode interface is the primary datatype for the entire Document Object Model...">DOMNode</a></code> attributes <code>parentNode</code>, <code>previousSibling</code>, and <code>nextSibling</code> have a null value for <code><aclass="el"href="classxercesc_1_1DOMAttr.html"title="The DOMAttr class refers to an attribute of an XML element.">DOMAttr</a></code> 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 <code><aclass="el"href="classxercesc_1_1DOMDocumentFragment.html"title="DOMDocumentFragment is a "lightweight" or "minimal" DOMDocument...">DOMDocumentFragment</a></code>. However, they can be associated with <code><aclass="el"href="classxercesc_1_1DOMElement.html"title="By far the vast majority of objects (apart from text) that authors encounter when...">DOMElement</a></code> nodes contained within a <code><aclass="el"href="classxercesc_1_1DOMDocumentFragment.html"title="DOMDocumentFragment is a "lightweight" or "minimal" DOMDocument...">DOMDocumentFragment</a></code>. In short, users of the DOM need to be aware that <code><aclass="el"href="classxercesc_1_1DOMAttr.html"title="The DOMAttr class refers to an attribute of an XML element.">DOMAttr</a></code> nodes have some things in common with other objects inheriting the <code><aclass="el"href="classxercesc_1_1DOMNode.html"title="The DOMNode interface is the primary datatype for the entire Document Object Model...">DOMNode</a></code> interface, but they also are quite distinct.<p>
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. <dlclass="since"compact><dt><b>Since:</b></dt><dd>DOM Level 1 </dd></dl>
The value of the attribute is returned as a string. Character and general entity references are replaced with their values. <dlclass="since"compact><dt><b>Since:</b></dt><dd>DOM Level 1 </dd></dl>
