Question

I am going to create an XML element in JavaScript to exchange data with server side. I found I can do it with document.createElement. But I do not know how to convert it to string. Is there any API in browser to make it easier? Or is there any JS library including this API?

EDIT: I found that browser API XMLSerializer, it should be the right way to serialize to string.

You can get the ‘outer-html’ by cloning the element,
adding it to an empty,’offstage’ container,
and reading the container’s innerHTML.

This example takes an optional second parameter.

Call document.getHTML(element, true) to include the element’s descendents.

document.getHTML= function(who, deep){
    if(!who || !who.tagName) return '';
    var txt, ax, el= document.createElement("div");
    el.appendChild(who.cloneNode(false));
    txt= el.innerHTML;
    if(deep){
        ax= txt.indexOf('>')+1;
        txt= txt.substring(0, ax)+who.innerHTML+ txt.substring(ax);
    }
    el= null;
    return txt;
}
