Parse XML

[mikhl]

Hi. I have some XML that is allways formatted like the snippet below. i am trying to parse it with a JS function but I am having no success what so ever.

 

<?xml version="1.0" encoding="ISO-8859-1" ?>
<root>
<offer>
	<bookTitle>Book Title</bookTitle>
	<catDesc>Category</catDesc>
	<bookPrice>£29.99</bookPrice>
</offer>
</root>

 

The JS I have to do this so far is below and I dont think it works very well at all. I seem to be able to get the first element (the title of the book) with the .firstChild function. But I cant access the others. I was also trying something with .nextSibling but having no luck there either.

 

function displayXML( data ){
   var root = data.documentElement; // get root element
   var nElements = root.childNodes.length;
   var retval = "";

   alert(nElements);

   var offer = root.childNodes;
   nOfferElems = offer.length;

   alert(nOfferElems);
   for(var j = 0; j < nElements; j++){
   
   		if(root.childNodes[j].hasChildNodes()){

	   for ( var n = 0; n < nOfferElems; n++) {
	   		
	      if (offer[j].childNodes[n].hasChildNodes()) {
	      	
	         var node = offer[j].childNodes[n];
	         retval += node.firstChild.nodeValue;
	         
	         for(var i = 0; i < nOfferElems; i++){
	         	alert('test - ' + (i+1));
	         	alert('nodeType: ' + node.childNodes[i].nodeType);
	         	if(node.childNodes[i].nodeType != 4){
	         		alert('node test - ' + (i+1));
		         	alert(node.childNodes[i].nodeValue);
		         	//node = node.nextSibling;
	         	}
	         }

	         retval += "<br />\n";
	      }
	   }//end for
	}//end if
   }//end for
   // the id of the element on the receiving html page
   // where the output will be displayed
   document.getElementById('special2').innerHTML = retval;
}
