JavaScript操作XML实例代码（获取新闻标题并分页，并分页）

复制代码 代码如下:

<?xml version="1.0" encoding="gb2312"?>
<NEWS>
<New id="1" name="测试新闻1" time="2010-2-18">
<NBody>新闻测试1新闻测试1</NBody>
</New>
<New id="2" name="测试新闻2" time="2010-2-18">
<NBody>新闻测试2新闻测试2</NBody>
</New>
<New id="3" name="测试新闻3" time="2010-2-18">
<NBody>新闻测试3新闻测试3</NBody>
</New>
<New id="4" name="测试新闻4" time="2010-2-18">
<NBody>新闻测试4新闻测试4</NBody>
</New>
<New id="5" name="测试新闻5" time="2010-2-18">
<NBody>新闻测试5新闻测试5</NBody>
</New>
<New id="6" name="测试新闻6" time="2010-2-18">
<NBody>新闻测试6新闻测试6</NBody>
</New>
