Get all tags with the wildcard:

var allElements = document.getElementsByTagName('*');
for(var i = 0; i < allElements.length; i++) {
    // ensure the element has an Id that is not empty and does exist
    // and string other than empty, '', will return true
    allElements[i].id && console.log(allElements[i].id);
}
