htmlparser2 convert xml object into string

Question

I'm having a little trouble getting the htmlparser2 module (using node.js) to output an xml string. Basically I'm parsing it in like so:

var htmlparser=require('htmlparser2');
function(xmlString,cb){
    var handler=new htmlparser.DomHandler(cb);
    var parser = new htmlparser.Parser(handler);
    parser.write(xmlString);
    parser.done();
}

Then I get an object called "dom", which I do some work on. After that work is done, I want to export it back into an XML string. I know that htmlparser.DomUtils.getOuterHTML(dom) works for HTML objects, but doesn't work for XML (at least not by default). I get back <undefined></undefined> when I call htmlparser.DomUtils.getOuterHTML(dom) on an xml dom.

Thanks in advance for any help you're able to offer! -Dylan

Fixed. Basically you need to use a second option in getOuterHTML... htmlparser.DomUtils.getOuterHTML(dom,{xmlMode:true}) If that doesn't work, try calling on the inner elems in the array like: htmlparser.DomUtils.getOuterHTML(dom[0],{xmlMode:true}) You'll have to wrap a for loop around it to get the whole document, but it works for me! — Dylan Williams
