Scan the entire dom of any page

  • 772

I need to scan the entire DOM of any page, is it possible?

I'm trying but I can't get absolutely everything, I only get a part

function findhead1() {
  var all = document.body.getElementsByTagName('*');

  for (var i = 0, max = all.length; i < max; i++) {
    console.log(all[i]);
  }
}
<body onload="findhead1()">
  <div class="postcell post-layout--right">

    <div class="post-text" itemprop="text">

      <p>I labeled some pixels of a picture as foreground and the rest of them are unlabeled yet. I want to use SVM and the labeled pixels's properties like color as SVM input to label the remaining pixels as background or foreground. Is that possible with
        one-class as input? Or do I need some pixels labeled as background (two-class input)?
        <br>Thanks in advance.<br> Edit: I found <br>
