Nonsense.

Neither the “innerHTML” property nor the “nodeValue” property of the first 
text child node are usually equivalent to the *text* content of the 
corresponding element.  Per W3C DOM Level 3 Core, all elements have a 
“textContent” property that can be read from and assigned to.

  document.getElementById("ierrmsg").textContent = "new msg";

It is supported by many DOM implementations, but not MSHTML < 9.  For the 
latter, you need to remove all child nodes and create a new text child node:

  if (typeof el.textContent != "undefined")
  {
    el.textContent = text;
  }
  else
  {
    while (el.lastChild) el.removeChild(el.lastChild);
    el.appendChild(document.createTextNode(text));
  }

See also jsx.dom.setTextContent().

An assignment to the “innerHTML” property is not equivalent to that because 
there the value right-hand side will be parsed, and the property is not 
available in XML mode.
