jdom中使用名字空间的问题

[wangsiye]

使用jdom生成xml文档，当父节点声明了一个名字空间，子节点使用相同的名字空间时，jdom好像默认子节点省略该名字空间的声明。现在我想让子节点同样出现该名字空间的声明，有没有什么办法。多谢各位大侠，急~~~~

就是怎样才能有如下的显示效果
<?xml version="1.0" encoding="UTF-8" ?>
- <SQ:ATTRIBUTES xmlns:SQ="http://www.mynamespace.com">
- <SQ:HEADER xmlns:SQ="http://www.http://www.mynamespace.com">
<SQ:FILENAME xmlns:SQ="http://www.sequoiabroadband.com">LordOfRing3.AVI</SQ:FILENAME>

支持相同名称父节点和子节点。我刚刚做了个实验，把代码给你，自己参考

可能是说的不太清楚，我指的不是相同名称的父节点和子节点，而是相同名字空间的元素的名字空间声明问题，举个例子
<?xml version="1.0" encoding="UTF-8" ?>
- <SQ:ATTRIBUTES xmlns:SQ="http://www.mynamespace.com">
- <SQ:HEADER>
<SQ:FILENAME>LordOfRing2.AVI</SQ:FILENAME>
<SQ:FILETYPE>video</SQ:FILETYPE>
<SQ:CONTENTID>OURID</SQ:CONTENTID>
<SQ:STATUS>0</SQ:STATUS>
<SQ:DESCRIPTION>This is the test movie.</SQ:DESCRIPTION>
<SQ:AUTHOR>John Woo</SQ:AUTHOR>
<SQ:OWNER>Jack Chen</SQ:OWNER>
<SQ:CREATEDATE>2003,7,22</SQ:CREATEDATE>
<SQ:THUMBNAIL>twas1_beijing_sell1_Sample.jpg</SQ:THUMBNAIL>
</SQ:HEADER>
</SQ:ATTRIBUTES>
名字空间是SQ, 但是想在每个元素后面都有名字空间的声明xmlns:SQ="http://www.mynamespace.com"
应该怎么做?
