<p>
Assume the following XML document:<elementExample id="demo"> <subelement1/> <subelement2><subsubelement/></subelement2> </elementExample> <p>
When represented using DOM, the top node is an <code>DOMElement</code> node for "elementExample", which contains two child <code>DOMElement</code> nodes, one for "subelement1" and one for "subelement2". "subelement1" contains no child nodes. <p>
Elements may have attributes associated with them; since the <code>DOMElement</code> interface inherits from <code><a class="el" href="classDOMNode.html">DOMNode</a></code>, the generic <code><a class="el" href="classDOMNode.html">DOMNode</a></code> interface method <code>getAttributes</code> may be used to retrieve the set of all attributes for an element. There are methods on the <code>DOMElement</code> interface to retrieve either an <code><a class="el" href="classDOMAttr.html">DOMAttr</a></code> object by name or an attribute value by name. In XML, where an attribute value may contain entity references, an <code><a class="el" href="classDOMAttr.html">DOMAttr</a></code> 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.<p>

Adds a new attribute.
<p>
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. In order to assign an attribute value that contains entity references, the user must create an <code><a class="el" href="classDOMAttr.html">DOMAttr</a></code> node plus any <code><a class="el" href="classDOMText.html">DOMText</a></code> and <code><a class="el" href="classDOMEntityReference.html">DOMEntityReference</a></code> nodes, build the appropriate subtree, and use <code>setAttributeNode</code> to assign it as the value of an attribute. <dl compact><dt><b>Parameters:</b></dt><dd>

Adds a new attribute.

If an attribute with the same local name and namespace URI is already present on the element, its prefix is changed to be the prefix part of the <code>qualifiedName</code>, and its value is changed to be the <code>value</code> 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.
