[newcomer2004]

如何使用dom对xml文件的结构进行修改，如下把table.xml改为table1.xml(加入分页的部分)
table.xml
<?xml version="1.0" encoding="GBK"?>
<printtable>

<table width="478" border="0" align="center">
<tr>
<td width="478" height="69" colspan="4" align="center" size="5">register table</td>
</tr>
<tr>
<td height="49" width="176">id：</td>
<td width="108">004</td>
<td width="126" align="right">name： </td>
<td width="50">JFrame</td>
</tr>
</table>
<table width="433" height="172" border="1" align="center">
<tr>
<td width="137" height="22">year</td>
<td width="137">month</td>
<td width="137">day</td>
</tr>
<tr>
<td width="137" height="22">hour</td>
<td width="137">minute</td>
<td width="137">second</td>
</tr>
</table>


<table width="733" height="172" border="1" align="center">

<td height="22" width="137">love;</td>
<td width="137">love;</td>
<td width="137">love;</td>

</table>
<table width="433" height="26" border="0" align="center">
