Revision 663259 of CharacterData

<p>{{APIRef}}</p>
<p>The <code><strong>CharacterData</strong></code> abstract interface represents a {{domxref("Node")}} object that contains characters. This is an abstract interface, meaning there aren't any object of type <code>CharacterData</code>: it is implemented by other interfaces, like {{domxref("Text")}}, {{domxref("Comment")}}, or {{domxref("ProcessingInstruction")}} which aren't abstract.</p>

  Is a {{domxref("DOMString")}} representing the textual data contained in this object.</dd>
 <dt>
  {{domxref("CharacterData.length")}} {{readonlyInline}}</dt>
 <dd>
  Returns an <code>unsigned long</code> representing the size of the string contained in <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>

<dl>
 <dt>
  {{domxref("CharacterData.appendData()")}}</dt>
 <dd>
  Appends the given {{domxref("DOMString")}} to the <code>CharacterData.data</code> string; when this method returns, <code>data</code> contains the concatenated {{domxref("DOMString")}}.</dd>
 <dt>
  {{domxref("CharacterData.deleteData()")}}</dt>
 <dd>
  Removes the specified amount of characters, starting at the specified offset, from the <code>CharacterData.data</code> string; when this method returns, <code>data</code> contains the shortened {{domxref("DOMString")}}.</dd>
 <dt>
  {{domxref("CharacterData.insertData()")}}</dt>
 <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>
 <dt>
  {{domxref("ChildNode.remove()")}} {{experimental_inline}}</dt>
 <dd>
  Removes the object from its parent children list.</dd>
 <dt>
  {{domxref("CharacterData.replaceData()")}}</dt>
 <dd>
  Replaces the specified amount of characters, starting at the specified offset, with the specified {{domxref("DOMString")}}; when this method returns, <code>data</code> contains the modified {{domxref("DOMString")}}.</dd>
 <dt>
  {{domxref("CharacterData.substringData()")}}</dt>
 <dd>
  Returns a {{domxref("DOMString")}} containing the part of <code>CharacterData.data</code> of the specified length and starting at the specified offset.</dd>
