<p>Note that QDomNamedNodeMap does not inherit from <a href="qdomnodelist.html">QDomNodeList</a>. QDomNamedNodeMaps do not provide any specific node ordering. Although nodes in a QDomNamedNodeMap may be accessed by an ordinal index, this is simply to allow a convenient enumeration of the contents of a QDomNamedNodeMap, and does not imply that the DOM specifies an ordering of the nodes.</p>
<p>The QDomNamedNodeMap is used in three places:</p>
<ol type="1">
<li><a href="qdomdocumenttype.html#entities">QDomDocumentType.entities</a>() returns a map of all entities described in the DTD.</li>
<li><a href="qdomdocumenttype.html#notations">QDomDocumentType.notations</a>() returns a map of all notations described in the DTD.</li>
<li><a href="qdomnode.html#attributes">QDomNode.attributes</a>() returns a map of all attributes of an element.</li>
</ol>
<p>Items in the map are identified by the name which QDomNode.name() returns. Nodes are retrieved using <a href="qdomnamednodemap.html#namedItem">namedItem</a>(), <a href="qdomnamednodemap.html#namedItemNS">namedItemNS</a>() or <a href="qdomnamednodemap.html#item">item</a>(). New nodes are inserted with <a href="qdomnamednodemap.html#setNamedItem">setNamedItem</a>() or <a href="qdomnamednodemap.html#setNamedItemNS">setNamedItemNS</a>() and removed with <a href="qdomnamednodemap.html#removeNamedItem">removeNamedItem</a>() or <a href="qdomnamednodemap.html#removeNamedItemNS">removeNamedItemNS</a>(). Use <a href="qdomnamednodemap.html#contains">contains</a>() to see if an item with the given name is in the named node map. The number of items is returned by <a href="qdomnamednodemap.html#length">length</a>().</p>
<p>Terminology: in this class we use "item" and "node" interchangeably.</p>

<h3 class="fn"><a name="QDomNamedNodeMap-2" />QDomNamedNodeMap.__init__ (<i>self</i>, <a href="qdomnamednodemap.html">QDomNamedNodeMap</a>)</h3><p>Constructs a copy of <i>n</i>.</p>
<h3 class="fn"><a name="contains" />bool QDomNamedNodeMap.contains (<i>self</i>, <a href="qstring.html">QString</a> <i>name</i>)</h3><p>Returns true if the map contains a node called <i>name</i>; otherwise returns false.</p>
<h3 class="fn"><a name="count" />int QDomNamedNodeMap.count (<i>self</i>)</h3><p>This function is provided for Qt API consistency. It is equivalent to <a href="qdomnamednodemap.html#length">length</a>().</p>
<h3 class="fn"><a name="isEmpty" />bool QDomNamedNodeMap.isEmpty (<i>self</i>)</h3><p>Returns true if the map is empty; otherwise returns false. This function is provided for Qt API consistency.</p>
<h3 class="fn"><a name="item" /><a href="qdomnode.html">QDomNode</a> QDomNamedNodeMap.item (<i>self</i>, int <i>index</i>)</h3><p>Retrieves the node at position <i>index</i>.</p>
<p>This can be used to iterate over the map. Note that the nodes in the map are ordered arbitrarily.</p>
<p>See also <a href="qdomnamednodemap.html#length">length</a>().</p>
<h3 class="fn"><a name="length" />unsigned long QDomNamedNodeMap.length (<i>self</i>)</h3><p>Returns the number of nodes in the map.</p>
<p>See also <a href="qdomnamednodemap.html#item">item</a>().</p>
<h3 class="fn"><a name="namedItem" /><a href="qdomnode.html">QDomNode</a> QDomNamedNodeMap.namedItem (<i>self</i>, <a href="qstring.html">QString</a> <i>name</i>)</h3><p>Returns the node called <i>name</i>.</p>
<p>If the named node map does not contain such a node, a <a href="qdomnode.html#isNull">null node</a> is returned. A node's name is the name returned by <a href="qdomnode.html#nodeName">QDomNode.nodeName</a>().</p>
<p>See also <a href="qdomnamednodemap.html#setNamedItem">setNamedItem</a>() and <a href="qdomnamednodemap.html#namedItemNS">namedItemNS</a>().</p>

<p>If the map does not contain such a node, a <a href="qdomnode.html#isNull">null node</a> is returned.</p>

<p>The function returns the removed node or a <a href="qdomnode.html#isNull">null node</a> if the map did not contain a node called <i>name</i>.</p>
<p>See also <a href="qdomnamednodemap.html#setNamedItem">setNamedItem</a>(), <a href="qdomnamednodemap.html#namedItem">namedItem</a>(), and <a href="qdomnamednodemap.html#removeNamedItemNS">removeNamedItemNS</a>().</p>

The name used by the map is the node name of <i>newNode</i> as returned by <a href="qdomnode.html#nodeName">QDomNode.nodeName</a>().</p>
<p>If the new node replaces an existing node, i.e. the map contains a node with the same name, the replaced node is returned.</p>
<p>See also <a href="qdomnamednodemap.html#namedItem">namedItem</a>(), <a href="qdomnamednodemap.html#removeNamedItem">removeNamedItem</a>(), and <a href="qdomnamednodemap.html#setNamedItemNS">setNamedItemNS</a>().</p>
