/><hr /><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;
d<span class="operator">.</span>setContent(someXML);

<hr /><h2>Method Documentation</h2><h3 class="fn"><a name="QDomNode" />QDomNode.__init__ (<i>self</i>)</h3><p>Constructs a <a href="qdomnode.html#isNull">null</a> node.</p>
<h3 class="fn"><a name="QDomNode-2" />QDomNode.__init__ (<i>self</i>, <a href="qdomnode.html">QDomNode</a>)</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>
<h3 class="fn"><a name="appendChild" /><a href="qdomnode.html">QDomNode</a> QDomNode.appendChild (<i>self</i>, <a href="qdomnode.html">QDomNode</a> <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>
<p><b>See also</b> <a href="qdomnode.html#insertBefore">insertBefore</a>(), <a href="qdomnode.html#insertAfter">insertAfter</a>(), <a href="qdomnode.html#replaceChild">replaceChild</a>(), and <a href="qdomnode.html#removeChild">removeChild</a>().</p>
<h3 class="fn"><a name="attributes" /><a href="qdomnamednodemap.html">QDomNamedNodeMap</a> QDomNode.attributes (<i>self</i>)</h3><p>Returns a named node map of all attributes. Attributes are only
provided for <a href="qdomelement.html">QDomElement</a>s.</p>
<p>Changing the attributes in the map will also change the
attributes of this <a href="qdomnode.html">QDomNode</a>.</p>
<h3 class="fn"><a name="childNodes" /><a href="qdomnodelist.html">QDomNodeList</a> QDomNode.childNodes (<i>self</i>)</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>p<span class="operator">></span>Hello <span class="operator"><</span>b<span class="operator">></span>you<span class="operator"><</span><span class="operator">/</span>b<span class="operator">></span><span class="operator"><</span><span class="operator">/</span>p<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><b>See also</b> <a href="qdomnode.html#firstChild">firstChild</a>() and <a href="qdomnode.html#lastChild">lastChild</a>().</p>
<h3 class="fn"><a name="clear" />QDomNode.clear (<i>self</i>)</h3><p>Converts the node into a null node; if it was not a null node
before, its type and contents are deleted.</p>
<p><b>See also</b> <a href="qdomnode.html#isNull">isNull</a>().</p>
<h3 class="fn"><a name="cloneNode" /><a href="qdomnode.html">QDomNode</a> QDomNode.cloneNode (<i>self</i>, bool <i>deep</i> = True)</h3><p>Creates a deep (not shallow) copy of the <a href="qdomnode.html">QDomNode</a>.</p>
<p>If <i>deep</i> is true, then the cloning is done recursively
which means that all the node's children are deep copied too. If
<i>deep</i> is false only the node itself is copied and the copy
will have no child nodes.</p>
<h3 class="fn"><a name="columnNumber" />int QDomNode.columnNumber (<i>self</i>)</h3><p>For nodes created by <a href="qdomdocument.html#setContent">QDomDocument.setContent</a>(), this
function returns the column number in the XML document where the
node was parsed. Otherwise, -1 is returned.</p>
<p>This function was introduced in Qt 4.1.</p>
<p><b>See also</b> <a href="qdomnode.html#lineNumber">lineNumber</a>() and <a href="qdomdocument.html#setContent">QDomDocument.setContent</a>().</p>
<h3 class="fn"><a name="firstChild" /><a href="qdomnode.html">QDomNode</a> QDomNode.firstChild (<i>self</i>)</h3><p>Returns the first child of the node. If there is no child node,
a <a href="qdomnode.html#isNull">null node</a> is returned.
Changing the returned node will also change the node in the
document tree.</p>
<p><b>See also</b> <a href="qdomnode.html#lastChild">lastChild</a>() and <a href="qdomnode.html#childNodes">childNodes</a>().</p>
<h3 class="fn"><a name="firstChildElement" /><a href="qdomelement.html">QDomElement</a> QDomNode.firstChildElement (<i>self</i>, QString <i>tagName</i> = '')</h3><p>Returns the first child element with tag name <i>tagName</i> if
tagName is non-empty; otherwise returns the first child element.
Returns a null element if no such child exists.</p>
<p><b>See also</b> <a href="qdomnode.html#lastChildElement">lastChildElement</a>(), <a href="qdomnode.html#previousSiblingElement">previousSiblingElement</a>(),
and <a href="qdomnode.html#nextSiblingElement">nextSiblingElement</a>().</p>
<h3 class="fn"><a name="hasAttributes" />bool QDomNode.hasAttributes (<i>self</i>)</h3><p>Returns true if the node has attributes; otherwise returns
false.</p>
<p><b>See also</b> <a href="qdomnode.html#attributes">attributes</a>().</p>
<h3 class="fn"><a name="hasChildNodes" />bool QDomNode.hasChildNodes (<i>self</i>)</h3><p>Returns true if the node has one or more children; otherwise
returns false.</p>
<h3 class="fn"><a name="insertAfter" /><a href="qdomnode.html">QDomNode</a> QDomNode.insertAfter (<i>self</i>, <a href="qdomnode.html">QDomNode</a> <i>newChild</i>, <a href="qdomnode.html">QDomNode</a> <i>refChild</i>)</h3><p>Inserts the node <i>newChild</i> after the child node
<i>refChild</i>. <i>refChild</i> must be a direct child of this
node. If <i>refChild</i> is <a href="qdomnode.html#isNull">null</a>
then <i>newChild</i> is appended as this 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 inserted
after <i>refChild</i>.</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>
