Replace HTML content using javaScript function onclick div?

I have the below snippet, which will output HTML, but I want texts A0100 and A0102 as combined string 

function closespan(val) {
  var parent = val.parentElement;
  parent.parentElement.removeChild(parent);
  var valHTML = document.getElementById("lblshowselected").innerHTML;
  var valSPLIT = valHTML.replace(/<img src="images\/delete.png" height="10">/, ",");
  var valTEXT = valSPLIT.innerText;
}
<div runat="server" id="lblshowselected">
  <div class="tknz-token">A0100<span class="tknz-token-x" onclick="closespan(this);"><img src="images/delete.png" height="10"></span></div>
  <div class="tknz-token">A0102<span class="tknz-token-x" onclick="closespan(this);"><img src="images/delete.png" height="10"></span></div>
</div>

Output
valHTML : "<div class="tknz-token">A0100<span class="tknz-token-x" onclick="closespan(this);"><img src="images/delete.png" height="10"></span></div><div class="tknz-token">A0102<span class="tknz-token-x" onclick="closespan(this);"><img src="images/delete.png" height="10"></span></div>"

Expected Output

A0100,A0102

Add your text as HTML instead of normal Text

function closespan(val) {
  debugger;
  var parent = val.parentElement;
  parent.parentElement.removeChild(parent);
  var valHTML = document.getElementById("lblshowselected");
  var valSPLIT = valHTML.replace(/<img src="images\/delete.png" height="10">/, ",");
  valHTML.innerHTML(valSPLIT);
}
<div runat="server" id="lblshowselected">
  <div class="tknz-token">A0100<span class="tknz-token-x" onclick="closespan(this);"><img src="images/delete.png" height="10"></span></div>
  <div class="tknz-token">A0102<span class="tknz-token-x" onclick="closespan(this);"><img src="images/delete.png" height="10"></span></div>
</div>

You need to get the tknz-token elements using getElementsByClassName() and iterate to get push textContent in an array.

Here is an example, I have only added code to get the textContent.

function closespan(val) {
  //Modified code
  var lbl = document.getElementById("lblshowselected");
  var arr = [];
  var tokens = lbl.getElementsByClassName('tknz-token');
  for (var i = 0; i < tokens.length; i++) {
    arr.push(tokens[i].textContent);
  }
  console.log(arr.join(','));
}
<div runat="server" id="lblshowselected">
  <div class="tknz-token">A0100<span class="tknz-token-x" onclick="closespan(this);"><img src="images/delete.png" height="10"></span></div>
  <div class="tknz-token">A0102<span class="tknz-token-x" onclick="closespan(this);"><img src="images/delete.png" height="10"></span></div>
</div>
