如何使用缩进保存MSXML2.DomDocument？(我认为它使用MXXMLWriter)

Question

我有一个MSXML2.DomDocument的实例.

随着缩进,我挥挥手来保存它.

此代码有效,但不会缩进:

var dom = new ActiveXObject("MSXML2.DomDocument");
// fiddle with dom here
dom.save(filename);

我想我可以使用MXXMLWriter对象来注入缩进.

怎么样？

这个做得好.

function saveDomWithIndent(dom, filename) {
    var writer =  new ActiveXObject("MSXML2.MXXMLWriter"),
        reader = new ActiveXObject("MSXML2.SAXXMLReader"),
        fso = new ActiveXObject("Scripting.FileSystemObject"),
        textStream = fso.CreateTextFile(filename, true);
    writer.indent = true;
    writer.omitXMLDeclaration = true;
    reader.contentHandler = writer;
    reader.parse(dom);
    textStream.Write(writer.output);
    textStream.Close();
}

像这样使用它:

var root, node, newnode, 
    dom = new ActiveXObject("MSXML2.DOMDocument.6.0");
dom.async = false;
dom.resolveExternals = false;
dom.load(fullpath);
root = dom.documentElement;
node = root.selectSingleNode("/root/node1");
if (node !== null) {
    newnode = dom.createElement('node2');
    newnode.text = "hello";
    root.appendChild(newnode);
    saveDomWithIndent(dom, fullpath);
}

我无法弄清楚如何调整缩进级别.它总是缩进tab.
