XML输出总是没有encoding属性？

Oliver_Ye 2009-08-07 04:33:49

<?xml   version="1.0"   encoding="UTF-8"?>   

  <Order>   

  <Item   number="1">   

  <SKU>12345</SKU>   

  <Description>Standard   Widget</Description>   

  </Item> ..... 

<Order>

xmlDoc=new ActiveXObject("Microsoft.XMLDOM");

xmlDoc.async=false;

xmlDoc.load("test.xml");

alert(xmlDoc.xml);

为什么显示出来的头文件只有<?xml version="1.0" ?> ，没有encoding="UTF-8"，这是为什么，因为这个问题，导致我保存中文数据时就出错，保存后的XML里没有头文件。
是什么原因导致这个问题的呢？

我想尝试人为在保存后的XML里添加头文件，但是不知道怎么在XML开始处添加这个头文件？
