<hr><h2><a name="details"></a>Detailed Description</h2>
The QDomElement class represents one element in the DOM tree.
<p>
Elements have a name() and zero or more attributes associated with them.
<p>Attributes of the element are represented by <a href="qdomattr.html">QDomAttr</a> objects, that can be
queried using the <a href="#bbd00e">attribute</a>() and <a href="#547880">attributeNode</a>() functions. You can set
attributes with the <a href="#137828">setAttribute</a>() and <a href="#d62ab8">setAttributeNode</a>() functions.
<p>For further information about the Document Objct Model see
<a href="http://www.w3.org/TR/REC-DOM-Level-1/">http://www.w3.org/TR/REC-DOM-Level-1/</a>.
For a more general introduction of the DOM implementation see the
<a href="qdomdocument.html">QDomDocument</a> documentation.
<hr><h2>Member Function Documentation</h2>
<h3 class="fn"><a name="5c5365"></a>QDomElement::QDomElement()</h3>
<p>Constructs an empty element. Use the <a href="qdomdocument.html#019a5f">QDomDocument::createElement</a>() function
to construct elements with content.
<h3 class="fn"><a name="ef0d2f"></a>QDomElement::QDomElement(constQDomElement&x)</h3>
<p>Copy constructor.
<p>The data of the copy is shared: modifying one will also change the other. If
you want to make a real copy, use <a href="qdomnode.html#7b27fa">cloneNode</a>() instead.
<h3 class="fn"><a name="0cd7d9"></a>QDomElement::~QDomElement()</h3>
<p>Destructor.
<h3 class="fn"><a href="qstring.html">QString</a><a name="bbd00e"></a>QDomElement::attribute(const<a href="qstring.html">QString</a>&name, const<a href="qstring.html">QString</a>&defValue=QString::null)const</h3>
<p>Returns the attribute with the name <em>name.</em> If the attribute does not exist
<em>defValue</em> is returned.
<p>See also <a href="#137828">setAttribute</a>(), <a href="#547880">attributeNode</a>() and <a href="#d62ab8">setAttributeNode</a>().
<h3 class="fn"><a href="qdomattr.html">QDomAttr</a><a name="547880"></a>QDomElement::attributeNode(const<a href="qstring.html">QString</a>&name)</h3>
<p>Returns the <a href="qdomattr.html">QDomAttr</a> object that corresponds to the attribute with the name
<em>name.</em> If no such attribute exists a null object is returned.
<p>See also <a href="#d62ab8">setAttributeNode</a>(), <a href="#bbd00e">attribute</a>() and <a href="#137828">setAttribute</a>().
<h3 class="fn"><a href="qdomnamednodemap.html">QDomNamedNodeMap</a><a name="ae6460"></a>QDomElement::attributes()const <code>[virtual]</code></h3>
<p>Returns a <a href="qdomnamednodemap.html">QDomNamedNodeMap</a> containing all attributes for this element.
<p>See also <a href="#bbd00e">attribute</a>(), <a href="#137828">setAttribute</a>(), <a href="#547880">attributeNode</a>() and <a href="#d62ab8">setAttributeNode</a>().
<p>Reimplemented from <a href="qdomnode.html#b801ac">QDomNode.</a>
<h3 class="fn"><a href="qdomnodelist.html">QDomNodeList</a><a name="0f90c8"></a>QDomElement::elementsByTagName(const<a href="qstring.html">QString</a>&tagname)const <code>[virtual]</code></h3>
<p>Returns a <a href="qdomnodelist.html">QDomNodeList</a> containing all descendant elements of this element
with the name <em>tagname.</em> The order they are in the node list, is the order
they are encountered in a preorder traversal of the element tree.
<h3 class="fn">bool<a name="687420"></a>QDomElement::hasAttribute(const<a href="qstring.html">QString</a>&name)const</h3>
<p>Returns TRUE is this element has an attribute with the name <em>name,</em>
otherwise FALSE.
<h3 class="fn">bool<a name="077a69"></a>QDomElement::isElement()const <code>[virtual]</code></h3>
<p>Returns TRUE.
<p>Reimplemented from <a href="qdomnode.html#c31d27">QDomNode.</a>
<h3 class="fn">QDomNode::NodeType<a name="4114d9"></a>QDomElement::nodeType()const <code>[virtual]</code></h3>
<p>Returns <code>ElementNode.</code>
<p>Reimplemented from <a href="qdomnode.html#4aab85">QDomNode.</a>
<h3 class="fn">void<a name="232d73"></a>QDomElement::normalize()</h3>
<p>Calling normalize() on an element brings all its children into a standard
form. This means, that adjacent <a href="qdomtext.html">QDomText</a> objects will be merged to
one text object (<a href="qdomcdatasection.html">QDomCDATASection</a> nodes are not merged).
<h3 class="fn">QDomElement&<a name="4a3983"></a>QDomElement::operator=(constQDomElement&x)</h3>
<p>Assignment operator.
<p>The data of the copy is shared: modifying one will also change the other. If
you want to make a real copy, use <a href="qdomnode.html#7b27fa">cloneNode</a>() instead.
<h3 class="fn">void<a name="dfe9bd"></a>QDomElement::removeAttribute(const<a href="qstring.html">QString</a>&name)</h3>
<p>Removes the attribute with the name <em>name</em> from this element.
<p>See also <a href="#137828">setAttribute</a>() and <a href="#bbd00e">attribute</a>().
<h3 class="fn"><a href="qdomattr.html">QDomAttr</a><a name="ef8b83"></a>QDomElement::removeAttributeNode(const<a href="qdomattr.html">QDomAttr</a>&oldAttr)</h3>
<p>Removes the attribute <em>oldAttr</em> from the element and returns it.
<p>See also <a href="#547880">attributeNode</a>() and <a href="#d62ab8">setAttributeNode</a>().
<h3 class="fn">void<a name="137828"></a>QDomElement::setAttribute(const<a href="qstring.html">QString</a>&name, const<a href="qstring.html">QString</a>&value)</h3>
<p>Sets the attribute with the name <em>name</em> to the string <em>value.</em> If the
attribute does not exist, a new one is created.
<h3 class="fn">void<a name="a5008c"></a>QDomElement::setAttribute(const<a href="qstring.html">QString</a>&name, doublevalue)</h3>
<p>This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
<h3 class="fn">void<a name="1c22b3"></a>QDomElement::setAttribute(const<a href="qstring.html">QString</a>&name, intvalue)</h3>
<p>This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
<h3 class="fn">void<a name="723152"></a>QDomElement::setAttribute(const<a href="qstring.html">QString</a>&name, uintvalue)</h3>
<p>This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
<h3 class="fn"><a href="qdomattr.html">QDomAttr</a><a name="d62ab8"></a>QDomElement::setAttributeNode(const<a href="qdomattr.html">QDomAttr</a>&newAttr)</h3>
<p>Adds the attribute <em>newAttr</em> to this element.
<p>If an attribute with the name <em>newAttr</em> exists in the element, the function
returns this attribute; otherwise the function returns a null attribute.
<p>See also <a href="#547880">attributeNode</a>().
<h3 class="fn">void<a name="26f15c"></a>QDomElement::setTagName(const<a href="qstring.html">QString</a>&name)</h3>
<p>Sets the tag name of this element.
<p>See also <a href="#a75b61">tagName</a>().
<h3 class="fn"><a href="qstring.html">QString</a><a name="a75b61"></a>QDomElement::tagName()const</h3>
<p>Returns the tag name of this element. For an XML element like
<pre> <img src="myimg.png">
</pre>
<p>the tagname would return "img".
<p>See also <a href="#26f15c">setTagName</a>().
<h3 class="fn"><a href="qstring.html">QString</a><a name="182f96"></a>QDomElement::text()const</h3>
<p>Returns the text contained inside this element.
<p>Example:
<pre> <h1>Hello <b><a href="qt.html">Qt</a></b> <![CDATA[<xml is cool>]]></h1>
</pre>
<p>The function text() of the QDomElement for the <h1> tag,
will return "Hello Qt <xml is cool>".
<p>Comments are ignored by this function. It evaluates only
<a href="qdomtext.html">QDomText</a> and <a href="qdomcdatasection.html">QDomCDATASection</a> objects.
