I solved my problem as below. I wrote a method which is convert html to element.

function htmlToElement(html) {
    var doc = new DOMParser().parseFromString(html, "text/html");
    return doc;
}

I got value like below.

var doc = htmlToElement(htmlString);
xPath = "/html/body/p";
var value = doc.evaluate(xPath, doc, null, XPathResult.ANY_TYPE, null).iterateNext().innerHTML;
