W3C是否等效于JavaScript DOMParser node.xml？

Question

I'm using DOMParser to parse some raw xml data loaded into a string. Given a particular Node object, I need to obtain the raw xml data for that node and everything beneath it in the tree.

For example, given:

<?xml version="1.0" encoding="UTF-8"?>
<root>
    <elem>
        <div>this is some text</div>
    </elem>
</root>

...and given a node object representing the <elem> element, I need to obtain:

    "<elem>
        <div>this is some text</div>
    </elem>"

...as a string.

W3C provides DOM Level 3 Load/Save spec but I am not aware of any native implementation in browsers. However, you can use de factor standard component XMLSerializer to get the xml content out.
