<p>{{APIRef("DOM")}}</p>
<p>A interface abstrata <strong>CharacterData </strong>representa um objeto {{domxref("Node")}} que contém caracteres. Esta é uma interface abstrata, o que significa que não há nenhum objeto do tipo <code>CharacterData</code>: ela é implementada por outras interfaces, como {{domxref("Text")}}, {{domxref("Comment")}} ou {{domxref("ProcessingInstruction")}}, que não são abstratas.</p>

<dl>
<dt>{{domxref("CharacterData.data")}}</dt>
<dd>É um {{domxref("DOMString")}} representando os dados textuais contidos neste objeto.</dd>
<dt>{{domxref("CharacterData.length")}} {{readonlyInline}}</dt>
<dd>Retorna um <code>unsigned long</code> representando o tamanho da string contida em <code>CharacterData.data</code>.</dd>
<dt>{{domxref("NonDocumentTypeChildNode.nextElementSibling")}} {{readonlyInline}}</dt>
<dd>Returns the {{domxref("Element")}} immediately following the specified one in its parent's children list, or <code>null</code> if the specified element is the last one in the list.</dd>
<dt>{{domxref("NonDocumentTypeChildNode.previousElementSibling")}} {{readonlyInline}}</dt>
<dd>Returns the {{domxref("Element")}} immediately prior to the specified one in its parent's children list, or <code>null</code> if the specified element is the first one in the list.</dd>

<dd>Inserts the specified characters, at the specified offset, in the <code>CharacterData.data</code> string; when this method returns, <code>data</code> contains the modified {{domxref("DOMString")}}.</dd>
