<div class="descr">
<h2>Detailed Description</h2>
<p>The QDomCharacterData class represents a generic string in the DOM.</p>
<p>Character data as used in XML specifies a generic data string. More specialized versions of this class are <a href="qdomtext.html">QDomText</a>, <a href="qdomcomment.html">QDomComment</a> and <a href="qdomcdatasection.html">QDomCDATASection</a>.</p>
<p>The data string is set with <a href="qdomcharacterdata.html#setData">setData</a>() and retrieved with <a href="qdomcharacterdata.html#data">data</a>(). You can retrieve a portion of the data string using <a href="qdomcharacterdata.html#substringData">substringData</a>(). Extra data can be appended with <a href="qdomcharacterdata.html#appendData">appendData</a>(), or inserted with <a href="qdomcharacterdata.html#insertData">insertData</a>(). Portions of the data string can be deleted with <a href="qdomcharacterdata.html#deleteData">deleteData</a>() or replaced with <a href="qdomcharacterdata.html#replaceData">replaceData</a>(). The length of the data string is returned by <a href="qdomcharacterdata.html#length">length</a>().</p>
<p>The node type of the node containing this character data is returned by <a href="qdomcharacterdata.html#nodeType">nodeType</a>().</p>
