为什么TABLE通过 DATASRC 绑定一个XML 文件后，无法删除TABLE 中的TR 对象？？？
为什么TABLE通过 DATASRC 绑定一个XML后，无法删除TABLE 中的TR 对象？
请高手解释一下！！！
整个HTML 文件如下：
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN ">

<id> 882 </id>
<datepart> 07071 </datepart>

{
var table = document.getElementById( "tableOne ");
try
{
for(var i=table.rows.length-1;i> =1;i--)
{
table.deleteRow(i);
}
}catch(e)
{
alert(e.name+e.message);
}
}
</script>
</HEAD>

个人认为deleteRow应该是要把这个对象删除掉，对象可能已经不存在与文档对象中了，因为这个方法没有返回值。
removeNode是把这个对象移除，但是这个对象还是存在的，这个方法有返回值，返回的就是移除的对象。

看看这样改后的现象。上面删除正常应该是因为table正在加载数据，但是数据被移除了，所以，就什么数据也加载不到了。
