There are several ways to get InnerHtml. Probably all you need to do is call: "element.innerText", but here's some other stuff I've played with:

Inner Text

/**
 * Recursively gets all text content, separated by a string.
 * Be warned there may be a slight difference between textContent and innerText.
 * @return {string} Text content.
 */
function getTextContentRecursiveFromLeaves(element, sepChar) {
  var hasChildren = element.children.length > 0;
  var hasTextContent = element.innerText;
  var allText = '';
  if (hasChildren) {
    for (var i = 0; i < element.children.length; i++) {
      console.log(i);
      var newText = getTextTextRecursiveFromLeaves(
        element.children[i], sepChar);
      if (allText && newText) { newText += sepChar; }
      allText += newText;
    }
  } else if (hasTextContent) {
    allText += element.innerText;
  }
  return allText;
}
 
/**
 * Gets inner text content by striping away HTML via Regex.
 * @return {string} Text content.
 */
function getInnerTextUsingRegex(element, sepChar) {
  var allText = element.innerHTML;
  var regex = /(<([^>]+)>)/ig;
  allText = allText.replace(regex, kSepChar);
  return allText;
}
