[Solved] Find closing tag in HTML string


some change in your code can work

see this line of codes

function highlightsText()
{

var range, sel;
if (window.getSelection) 
{
sel = window.getSelection();
if (sel.getRangeAt) {
range = sel.getRangeAt(0);
}
document.designMode = "on";
if (range) {
sel.removeAllRanges();
sel.addRange(range);
}
if ( !document.execCommand("HiliteColor", false, "yellow") ) {

document.execCommand("BackColor", false, "yellow");
}
document.designMode = "off";
} 
else if (document.selection && document.selection.createRange) {
range = document.selection.createRange();
range.execCommand("BackColor", false, "yellow");
}


    var newDate = new Date;
    var randomnumber= newDate.getTime();
   var nodeList = document.querySelectorAll(".Apple-style-span");
    for (var i = 0, length = nodeList.length; i < length; i++) {
         nodeList[i].id = randomnumber;  
        }


         var div = document.getElementById(randomnumber);

    var imageTag = document.createElement("img");
    imageTag.id=randomnumber;
    imageTag.setAttribute("src","notes.png");

    var linkTxt = document.createElement("a");
    linkTxt.id=randomnumber;
    linkTxt.setAttribute("href","highlight:"+randomnumber);


div.appendChild(linkTxt);

range.insertNode(div);


    return document.body.innerHTML+"<noteseparator>"+randomnumber+"<noteseparator>"+range.toString();

}   

You need make some adjustments in this code.
