<P>目前，我們已經能夠通過DOM獲取XML文檔中的信息了。如前所述，通過DOM還可以動態地更改XML文檔中的內容。下面我們仍舊使用上面的client.xml文檔，通過實例來說明如何更改XML文檔中的內容。</P>
<P>假如我們希望在addressbook.xml中，給第一個person元素增添一個字符串為"北大方正"的company元素，實現這一添加元素操作的語句如下：</P>
<DIV align=center>

<TABLE width="80%" border=1>
<TBODY>
<TR>
<TD width="100%">node = root.childNodes.item(0)<BR>newNode =
