如何使用缩进保存MSXML2.DomDocument？ （我认为它使用MXXMLWriter） [英] How can I save an MSXML2.DomDocument with indenting? (I think it uses MXXMLWriter)

问题描述

我有一个MSXML2.DomDocument的实例。

I have an instance of MSXML2.DomDocument.

我挥动来保存它，并缩进。

I wave to save it, with indenting.

此代码有效，但不会缩进：

This code works, but does not indent:

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。

I think I can use an MXXMLWriter object to inject indenting.

怎么样？

推荐答案

这个做得很好。

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：

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。它总是用标签缩进。

I could not figure out how to adjust the indent level. It always indents with a tab.
