How can I save an MSXML2.DomDocument with indenting? (I think it uses MXXMLWriter)


I have an instance of MSXML2.DomDocument.

I wave to save it, with indenting.

This code works, but does not indent:

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

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

How?


Solution

  • This oughta do it.

    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();
    }
    

    Use it like this:

    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);
    }
    

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