Posted 2020-07-17 GentleMint

var str = "<sup><div class=\"he‘s\"/></sup><span id=\"cs\"/>";

function removeCloseTag(str) {
    var regCloseTag = /<[^>]+\/>/,
        regTagName = /[^<][^\s]+/,
        tmp,
        tagName;

    while((tmp = str.match(regCloseTag)) && tmp.length > 0){
        tagName = tmp[0].match(regTagName);
        str = str.replace(/\/>/, ‘></‘+tagName+‘>‘);
    }

    return str;
}

var res = removeCloseTag(str); //<sup><div class="he‘s"></div></sup><span id="cs"></span>
