Solution 1

"parentElement" is called "parentNode" in Mozilla. I strongly suggest that you use jQuery[^] to get cross browser issues out of the way. Here's a page to help you get started using jQuery: Tutorials:How jQuery Works[^].

<script type="text/javascript">
 
  //  code for IE7+, Firefox, Chrome, Opera, Safari
  if (navigator.appName == 'Microsoft Internet Explorer')
  {
	var xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
        xmlDoc.async=false;
	xmlDoc.load("demo.xml");
  }
  else
  {
        xmlhttp = new XMLHttpRequest();
        xmlhttp.open("GET","demo.xml",false);
        xmlhttp.send();
        xmlDoc = xmlhttp.responseXML;
  }
	var a;
	a = xmlDoc.getElementsByTagName("CurIP")[0].childNodes[0].nodeValue; 
        document.write(a);
        
   	
</script>

These xml rendering supports in all browser.
