在注释之间移动HTML代码（包括注释）

Question

I have the below HTML special content between comments

<p>Regular text</p>
<p>Regular text</p>
<!--Special Content-->
<p>Special Content 1</p>
<p>Special Content 2</p>
<!--/Special Content-->
<p>Regular text</p>
<p>Regular text</p>
<p id="reference">Place special content with comments below this <p> element</p>

I need to wrap the HTML content between the comments <!--Special Content--> and <!--/Special Content--> including the comments themselves into a <div> and move it below the <p id="reference"> element.

I have no access to the actual HTML template so it needs to be done via JavaScript or JQuery.

I haven't be able to find a way to wrap the content including the comments so far.

End result should be:

<p>Regular text</p>
<p>Regular text</p>
<p>Regular text</p>
<p>Regular text</p>
<p id="reference">Place special content with comments below this <p> element</p>
<div id="wrapper">
  <!--Special Content-->
  <p>Special Content 1</p>
  <p>Special Content 2</p>
  <!--/Special Content-->
</div>

I appreciate your ideas.

 var dataElem = document.getElementById("data"); var doMove = false; var toMove = []; for (var i = 0; i < dataElem.childNodes.length; i++) { var node = dataElem.childNodes[i]; if (node.nodeType === Node.COMMENT_NODE && node.data === "Special Content") { doMove = true; } if (doMove) { toMove.push(node); } if (node.nodeType === Node.COMMENT_NODE && node.data === "/Special Content") { doMove = false; } } var targetElem = document.createElement("DIV"); targetElem.setAttribute("id", "wrapper"); dataElem.insertBefore(targetElem, document.getElementById("reference").nextSibling); for (var i = 0; i < toMove.length; i++) { targetElem.appendChild(toMove[i]); } 

 <div id="data"> <p>Regular text</p> <p>Regular text</p> <!--Special Content--> <p>Special Content 1</p> <p>Special Content 2</p> <!--/Special Content--> <p>Regular text</p> <p>Regular text</p> <p id="reference">Place special content with comments below this <p> element</p> </div>

This will move all the content between your special comment tags after the reference id tag.

 let move = false; let parse = $('body').contents().each(function(k,v){ if( v.nodeType === 8 ){ if( v.nodeValue === "Special Content" ) move = true; else if( v.nodeValue === "/Special Content") move = false; } else if(move && v.nodeType === 1) $(v).insertAfter('#reference'); });
