  • `var all = document.getElementsByTagName("*");` see http://stackoverflow.com/questions/4256339/javascript-how-to-loop-through-all-dom-elements-on-a-page – helderdarocha Feb 26 '14 at 22:17
  • You can also do it recursively, getting all children, checking their DOM type, and either getting their name, value and attributes or recursing again if a node-set is found. – helderdarocha Feb 26 '14 at 22:19

You can use browser built-in xml parser to do so. But it is more convenient to use JSON with Javascript.

var txt = "..."; // here is your xml as a string

if (window.DOMParser) {
    parser=new DOMParser();
    xmlDoc=parser.parseFromString(txt,"text/xml");
} else { // Internet Explorer
    xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
    xmlDoc.async=false;
    xmlDoc.loadXML(txt); 
}

Then you can manipulate with xmlDoc as with DOM tree. For example lets alert all tag names and values:

var tags = xmlDoc.getElementsByTagName('*');
for (var i = 0; i < tags.length; i++) {
    alert(tags[i].nodeName + ' = ' + tags[i].firstChild.nodeValue);
}

Or probably XSLT can help you (Click on the "Try it Yourself" button to see how it works.). This is way to transform XML data to html page.
