Unescape HTML entities in Javascript?

Question

I have some Javascript code that communicates with an XML-RPC backend. The XML-RPC returns strings of the form:

Answer 1

CMS' answer works fine, unless the HTML you want to unescape is very long, longer than 65536 chars. Because then in Chrome the inner HTML gets split into many child nodes, each one at most 65536 long, and you need to concatenate them. This function works also for very long strings:

function unencodeHtmlContent(escapedHtml) {
  var elem = document.createElement('div');
  elem.innerHTML = escapedHtml;
  var result = '';
  // Chrome splits innerHTML into many child nodes, each one at most 65536.
  // Whereas FF creates just one single huge child node.
  for (var i = 0; i < elem.childNodes.length; ++i) {
    result = result + elem.childNodes[i].nodeValue;
  }
  return result;
}
