Method to change self-closing tags to explicit tags in Javascript?
<span class="label"/>

<span class ="label"></span>

var div = document.createElement('div');
div.innerHTML = '<span/>';
var span = div.getElementsByTagName('span')[0];
span.innerHTML = 'hello';
alert(span.innerHTML);

var splitSpan = textHTML.split(">");
var i=0;
for(i=0;i<splitSpan.length-1;i++){
    var lengthSpan = splitSpan[i].length;
    var subSpan = splitSpan[i].substring(1,5);
    var endSpan = splitSpan[i].charAt(lengthSpan-1);

    if(subSpan=="span" && endSpan=="/")
    {

        splitSpan[i]=setCharAt(splitSpan[i],lengthSpan-1,'>');
        splitSpan[i]=splitSpan[i]+"</span>";
    }
    else
    {

        splitSpan[i]=splitSpan[i]+">";
    }

if(index > str.length-1) return str;

return str.substr(0,index) + chr + str.substr(index+1);
