<!-- $$$QDomElement-description -->
<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>The <a href="qdomelement.html">QDomElement</a> class represents one element in the DOM tree.</p>
<p>Elements have a <a href="qdomelement.html#tagName">tagName</a>() and zero or more attributes associated with them. The tag name can be changed with <a href="qdomelement.html#setTagName">setTagName</a>().</p>
<p>Element attributes are represented by <a href="qdomattr.html">QDomAttr</a> objects that can be queried using the <a href="qdomelement.html#attribute">attribute</a>() and <a href="qdomelement.html#attributeNode">attributeNode</a>() functions. You can set attributes with the <a href="qdomelement.html#setAttribute">setAttribute</a>() and <a href="qdomelement.html#setAttributeNode">setAttributeNode</a>() functions. Attributes can be removed with <a href="qdomelement.html#removeAttribute">removeAttribute</a>(). There are namespace-aware equivalents to these functions, i.e&#x2e; <a href="qdomelement.html#setAttributeNS">setAttributeNS</a>(), <a href="qdomelement.html#setAttributeNodeNS">setAttributeNodeNS</a>() and <a href="qdomelement.html#removeAttributeNS">removeAttributeNS</a>().</p>
<p>If you want to access the text of a node use <a href="qdomelement.html#text">text</a>(), e.g&#x2e;</p>
<pre class="cpp">

  <span class="type"><a href="qdomelement.html#QDomElement">QDomElement</a></span> e <span class="operator">=</span> <span class="comment">//...</span>
  <span class="comment">//...</span>
  <span class="type"><a href="../qtcore/qstring.html">QString</a></span> s <span class="operator">=</span> e<span class="operator">.</span>text()

</pre>
<p>The <a href="qdomelement.html#text">text</a>() function operates recursively to find the text (since not all elements contain text). If you want to find all the text in all of a node's children, iterate over the children looking for <a href="qdomtext.html">QDomText</a> nodes, e.g&#x2e;</p>
<pre class="cpp">

  <span class="type"><a href="../qtcore/qstring.html">QString</a></span> text;
  <span class="type"><a href="qdomelement.html#QDomElement">QDomElement</a></span> element <span class="operator">=</span> doc<span class="operator">.</span>documentElement();
  <span class="keyword">for</span>(<span class="type"><a href="qdomnode.html#QDomNode">QDomNode</a></span> n <span class="operator">=</span> element<span class="operator">.</span>firstChild(); <span class="operator">!</span>n<span class="operator">.</span>isNull(); n <span class="operator">=</span> n<span class="operator">.</span>nextSibling())
  {
      <span class="type"><a href="qdomtext.html">QDomText</a></span> t <span class="operator">=</span> n<span class="operator">.</span>toText();
      <span class="keyword">if</span> (<span class="operator">!</span>t<span class="operator">.</span>isNull())
          text <span class="operator">+</span><span class="operator">=</span> t<span class="operator">.</span>data();
  }

</pre>
<p>Note that we attempt to convert each node to a text node and use <a href="qdomelement.html#text">text</a>() rather than using <a href="qdomnode.html#firstChild">firstChild</a>().<a href="qdomnode.html#toText">toText</a>().data() or n.<a href="qdomnode.html#toText">toText</a>().data() directly on the node, because the node may not be a text element.</p>
<p>You can get a list of all the decendents of an element which have a specified tag name with <a href="qdomelement.html#elementsByTagName">elementsByTagName</a>() or <a href="qdomelement.html#elementsByTagNameNS">elementsByTagNameNS</a>().</p>
<p>To browse the elements of a dom document use <a href="qdomnode.html#firstChildElement">firstChildElement</a>(), <a href="qdomnode.html#lastChildElement">lastChildElement</a>(), <a href="qdomnode.html#nextSiblingElement">nextSiblingElement</a>() and <a href="qdomnode.html#previousSiblingElement">previousSiblingElement</a>(). For example, to iterate over all child elements called &quot;entry&quot; in a root element called &quot;database&quot;, you can use:</p>
<pre class="cpp">

  <span class="type"><a href="qdomdocument.html">QDomDocument</a></span> doc <span class="operator">=</span> <span class="comment">// ...</span>
  <span class="type"><a href="qdomelement.html#QDomElement">QDomElement</a></span> root <span class="operator">=</span> doc<span class="operator">.</span>firstChildElement(<span class="string">&quot;database&quot;</span>);
  <span class="type"><a href="qdomelement.html#QDomElement">QDomElement</a></span> elt <span class="operator">=</span> root<span class="operator">.</span>firstChildElement(<span class="string">&quot;entry&quot;</span>);
  <span class="keyword">for</span> (; <span class="operator">!</span>elt<span class="operator">.</span>isNull(); elt <span class="operator">=</span> elt<span class="operator">.</span>nextSiblingElement(<span class="string">&quot;entry&quot;</span>)) {
      <span class="comment">// ...</span>
  }

</pre>
