<!-- $$$QDomNode-description -->
<div class="descr">
<h2>Detailed Description</h2>
<p>The QDomNode class is the base class for all the nodes in a DOM tree.</p>
<p>Many functions in the DOM return a QDomNode.</p>
<p>You can find out the type of a node using <a href="qdomnode.html#isAttr">isAttr</a>(), <a href="qdomnode.html#isCDATASection">isCDATASection</a>(), <a href="qdomnode.html#isDocumentFragment">isDocumentFragment</a>(), <a href="qdomnode.html#isDocument">isDocument</a>(), <a href="qdomnode.html#isDocumentType">isDocumentType</a>(), <a href="qdomnode.html#isElement">isElement</a>(), <a href="qdomnode.html#isEntityReference">isEntityReference</a>(), <a href="qdomnode.html#isText">isText</a>(), <a href="qdomnode.html#isEntity">isEntity</a>(), <a href="qdomnode.html#isNotation">isNotation</a>(), <a href="qdomnode.html#isProcessingInstruction">isProcessingInstruction</a>(), <a href="qdomnode.html#isCharacterData">isCharacterData</a>() and <a href="qdomnode.html#isComment">isComment</a>().</p>
<p>A QDomNode can be converted into one of its subclasses using <a href="qdomnode.html#toAttr">toAttr</a>(), <a href="qdomnode.html#toCDATASection">toCDATASection</a>(), <a href="qdomnode.html#toDocumentFragment">toDocumentFragment</a>(), <a href="qdomnode.html#toDocument">toDocument</a>(), <a href="qdomnode.html#toDocumentType">toDocumentType</a>(), <a href="qdomnode.html#toElement">toElement</a>(), <a href="qdomnode.html#toEntityReference">toEntityReference</a>(), <a href="qdomnode.html#toText">toText</a>(), <a href="qdomnode.html#toEntity">toEntity</a>(), <a href="qdomnode.html#toNotation">toNotation</a>(), <a href="qdomnode.html#toProcessingInstruction">toProcessingInstruction</a>(), <a href="qdomnode.html#toCharacterData">toCharacterData</a>() or <a href="qdomnode.html#toComment">toComment</a>(). You can convert a node to a null node with <a href="qdomnode.html#clear">clear</a>().</p>
<p>Copies of the QDomNode class share their data using explicit sharing. This means that modifying one node will change all copies. This is especially useful in combination with functions which return a QDomNode, e.g. <a href="qdomnode.html#firstChild">firstChild</a>(). You can make an independent (deep) copy of the node with <a href="qdomnode.html#cloneNode">cloneNode</a>().</p>
<p>A QDomNode can be null, much like a null pointer. Creating a copy of a null node results in another null node. It is not possible to modify a null node, but it is possible to assign another, possibly non-null node to it. In this case, the copy of the null node will remain null. You can check if a QDomNode is null by calling <a href="qdomnode.html#isNull">isNull</a>(). The empty constructor of a QDomNode (or any of the derived classes) creates a null node.</p>
<p>Nodes are inserted with <a href="qdomnode.html#insertBefore">insertBefore</a>(), <a href="qdomnode.html#insertAfter">insertAfter</a>() or <a href="qdomnode.html#appendChild">appendChild</a>(). You can replace one node with another using <a href="qdomnode.html#replaceChild">replaceChild</a>() and remove a node with <a href="qdomnode.html#removeChild">removeChild</a>().</p>
<p>To traverse nodes use <a href="qdomnode.html#firstChild">firstChild</a>() to get a node's first child (if any), and <a href="qdomnode.html#nextSibling">nextSibling</a>() to traverse. QDomNode also provides <a href="qdomnode.html#lastChild">lastChild</a>(), <a href="qdomnode.html#previousSibling">previousSibling</a>() and <a href="qdomnode.html#parentNode">parentNode</a>(). To find the first child node with a particular node name use <a href="qdomnode.html#namedItem">namedItem</a>().</p>
<p>To find out if a node has children use <a href="qdomnode.html#hasChildNodes">hasChildNodes</a>() and to get a list of all of a node's children use <a href="qdomnode.html#childNodes">childNodes</a>().</p>
<p>The node's name and value (the meaning of which varies depending on its type) is returned by <a href="qdomnode.html#nodeName">nodeName</a>() and <a href="qdomnode.html#nodeValue">nodeValue</a>() respectively. The node's type is returned by <a href="qdomnode.html#nodeType">nodeType</a>(). The node's value can be set with <a href="qdomnode.html#setNodeValue">setNodeValue</a>().</p>
<p>The document to which the node belongs is returned by <a href="qdomnode.html#ownerDocument">ownerDocument</a>().</p>
<p>Adjacent <a href="qdomtext.html">QDomText</a> nodes can be merged into a single node with <a href="qdomnode.html#normalize">normalize</a>().</p>
<p><a href="qdomelement.html">QDomElement</a> nodes have attributes which can be retrieved with <a href="qdomnode.html#attributes">attributes</a>().</p>
<p><a href="qdomelement.html">QDomElement</a> and <a href="qdomattr.html">QDomAttr</a> nodes can have namespaces which can be retrieved with <a href="qdomnode.html#namespaceURIx">namespaceURI</a>(). Their local name is retrieved with <a href="qdomnode.html#localName">localName</a>(), and their prefix with <a href="qdomnode.html#prefix">prefix</a>(). The prefix can be set with <a href="qdomnode.html#setPrefix">setPrefix</a>().</p>
<p>You can write the XML representation of the node to a text stream with <a href="qdomnode.html#save">save</a>().</p>
<p>The following example looks for the first element in an XML document and prints the names of all the elements that are its direct children.</p>
<pre class="cpp"> <span class="type"><a href="qdomdocument.html">QDomDocument</a></span> d;

<h3 class="fn"><a name="QDomNode-2"></a>QDomNode::<span class="name">QDomNode</span> ( const <span class="type">QDomNode</span> & <i>n</i> )</h3>
<p>Constructs a copy of <i>n</i>.</p>
<p>The data of the copy is shared (shallow copy): modifying one node will also change the other. If you want to make a deep copy, use <a href="qdomnode.html#cloneNode">cloneNode</a>().</p>
<!-- @@@QDomNode -->
<!-- $$$~QDomNode[overload1]$$$~QDomNode -->

<h3 class="fn"><a name="appendChild"></a><span class="type">QDomNode</span> QDomNode::<span class="name">appendChild</span> ( const <span class="type">QDomNode</span> & <i>newChild</i> )</h3>
<p>Appends <i>newChild</i> as the node's last child.</p>
<p>If <i>newChild</i> is the child of another node, it is reparented to this node. If <i>newChild</i> is a child of this node, then its position in the list of children is changed.</p>
<p>If <i>newChild</i> is a <a href="qdomdocumentfragment.html">QDomDocumentFragment</a>, then the children of the fragment are removed from the fragment and appended.</p>
<p>If <i>newChild</i> is a <a href="qdomelement.html">QDomElement</a> and this node is a <a href="qdomdocument.html">QDomDocument</a> that already has an element node as a child, <i>newChild</i> is not added as a child and a null node is returned.</p>
<p>Returns a new reference to <i>newChild</i> on success or a <a href="qdomnode.html#isNull">null node</a> on failure.</p>
<p>Calling this function on a null node(created, for example, with the default constructor) does nothing and returns a <a href="qdomnode.html#isNull">null node</a>.</p>
<p>The DOM specification disallow inserting attribute nodes, but for historical reasons, QDom accepts them anyway.</p>

<h3 class="fn"><a name="childNodes"></a><span class="type"><a href="qdomnodelist.html">QDomNodeList</a></span> QDomNode::<span class="name">childNodes</span> () const</h3>
<p>Returns a list of all direct child nodes.</p>
<p>Most often you will call this function on a <a href="qdomelement.html">QDomElement</a> object.</p>
<p>For example, if the XML document looks like this:</p>
<pre class="cpp"> <span class="operator"><</span>body<span class="operator">></span>
<span class="operator"><</span>h1<span class="operator">></span>Heading<span class="operator"><</span><span class="operator">/</span>h1<span class="operator">></span>

<span class="operator"><</span><span class="operator">/</span>body<span class="operator">></span></pre>
<p>Then the list of child nodes for the "body"-element will contain the node created by the &lt;h1&gt; tag and the node created by the &lt;p&gt; tag.</p>
<p>The nodes in the list are not copied; so changing the nodes in the list will also change the children of this node.</p>

<p>Returns true if <i>n</i> and this DOM node are equal; otherwise returns false.</p>
<p>Any instance of <a href="qdomnode.html">QDomNode</a> acts as a reference to an underlying data structure in <a href="qdomdocument.html">QDomDocument</a>. The test for equality checks if the two references point to the same underlying node. For example:</p>
<pre class="cpp"> <span class="type"><a href="qdomdocument.html">QDomDocument</a></span> document;
<span class="type"><a href="qdomelement.html">QDomElement</a></span> element1 <span class="operator">=</span> document<span class="operator">.</span>documentElement();
<span class="type"><a href="qdomelement.html">QDomElement</a></span> element2 <span class="operator">=</span> element1;</pre>
<p>The two nodes (<a href="qdomelement.html">QDomElement</a> is a <a href="qdomnode.html">QDomNode</a> subclass) both refer to the document's root element, and <tt>element1 == element2</tt> will return true. On the other hand:</p>
<pre class="cpp"> <span class="type"><a href="qdomelement.html">QDomElement</a></span> element3 <span class="operator">=</span> document<span class="operator">.</span>createElement(<span class="string">"MyElement"</span>);
<span class="type"><a href="qdomelement.html">QDomElement</a></span> element4 <span class="operator">=</span> document<span class="operator">.</span>createElement(<span class="string">"MyElement"</span>);</pre>
<p>Even though both nodes are empty elements carrying the same name, <tt>element3 == element4</tt> will return false because they refer to two different nodes in the underlying data structure.</p>
