<hr><h2><a name="details"></a>Detailed Description</h2>
The QDomAttr class represents one attribute of a <a href="qdomelement.html">QDomElement</a>
<p>
For example, the following piece of XML gives an element with no children,
but two attributes:
<p><pre> <link href="http://www.trolltech.com" color="red" />
</pre>
<p>One can use the attributes of an element with code similar to:
<p><pre> <a href="qdomelement.html">QDomElement</a> e = ....;
<a href="qdomattr.html">QDomAttr</a> a = e.<a href="qdomelement.html#97b2c5">attributeNode</a>( "href" );
cout << a.<a href="#7dea09">value</a>() << endl // gives "http://www.trolltech.com"
a.<a href="#fa7855">setValue</a>( "http://doc.trolltech.com" );
<a href="qdomattr.html">QDomAttr</a> a2 = e.<a href="qdomelement.html#97b2c5">attributeNode</a>( "href" );
cout << a2.<a href="#7dea09">value</a>() << endl // gives "http://doc.trolltech.com"
</pre>
<p>This example also shows that changing an attribute received from an element
changes the attribute of the element. If you do not want to change the
value of the element's attribute you have to use <a href="qdomnode.html#8f17f1">cloneNode</a>() to get an
independent copy of the attribute.
<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.

<h3 class="fn"><a name="531cef"></a>QDomAttr::QDomAttr()</h3>
<p>Constructs an empty attribute.
<h3 class="fn"><a name="2f9604"></a>QDomAttr::QDomAttr(constQDomAttr&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#8f17f1">cloneNode</a>() instead.
<h3 class="fn"><a name="e54bbf"></a>QDomAttr::~QDomAttr()</h3>
<p>Destructor.
<h3 class="fn">bool<a name="b76ec6"></a>QDomAttr::isAttr()const <code>[virtual]</code></h3>
<p>Returns TRUE.
<p>Reimplemented from <a href="qdomnode.html#c5ede2">QDomNode.</a>
<h3 class="fn"><a href="qstring.html">QString</a><a name="4710bf"></a>QDomAttr::name()const <code>[virtual]</code></h3>
<p>Returns the name of the attribute.
<h3 class="fn">QDomNode::NodeType<a name="036b00"></a>QDomAttr::nodeType()const <code>[virtual]</code></h3>
<p>Returns <code>AttributeNode.</code>
<p>Reimplemented from <a href="qdomnode.html#46495e">QDomNode.</a>
<h3 class="fn">QDomAttr&<a name="179955"></a>QDomAttr::operator=(constQDomAttr&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#8f17f1">cloneNode</a>() instead.
<h3 class="fn">void<a name="fa7855"></a>QDomAttr::setValue(const<a href="qstring.html">QString</a>&v) <code>[virtual]</code></h3>
<p>Sets the value of the attribute to <em>v.</em>
<p>See also <a href="#7dea09">value</a>().
<h3 class="fn">bool<a name="590558"></a>QDomAttr::specified()const <code>[virtual]</code></h3>
<p>Returns TRUE if the attribute has been expicitly specified in the XML
document or was set by the user with <a href="#fa7855">setValue</a>(), otherwise FALSE.
<p>See also <a href="#fa7855">setValue</a>().
<h3 class="fn"><a href="qstring.html">QString</a><a name="7dea09"></a>QDomAttr::value()const <code>[virtual]</code></h3>
<p>Returns the current value of the attribute. Returns a null string
when the attribute has not been specified.
