简单问题，关于dom

[jemmylau]

如何利用dom给xml文件添加
<?xml version="1.0" encoding="GB2312"?>
<?xml-stylesheet href="xsl/showtopic.xsl" type="text/xsl"?>
这样的内容呢？

[孟子E章]

createProcessingInstruction Method

Creates a processing instruction node that contains the supplied target and data.

var objXMLDOMProcessingInstruction =
oXMLDOMDocument.createProcessingInstruction(target, data);

例子：

var xmlDoc = new ActiveXObject("Msxml2.DOMDocument");
var pi;
xmlDoc.async = false;
xmlDoc.load("books.xml");
pi = xmlDoc.createProcessingInstruction("xml", "version=\"1.0\"");
xmlDoc.insertBefore(pi, xmlDoc.childNodes.item(0));
alert(xmlDoc.xml);
