Answer by geocodezip for Google Map Api v3 and XML feed

The Google Maps Javascript API v3 does not contain any XML parsing. But you can parse XML with javascript and display the results on a Google Maps Javascript API v3 map.

Your code currently parses XML of this format:

<Deal Latitude="38.989869999999996" Longitude="-110.13261" Deal_ID="201090531" Price="9.50" />

function from geoxml3 that returns the text content of an element (like <lat>):

//nodeValue: Extract the text value of a DOM node, with leading and trailing whitespace trimmedgeoXML3.nodeValue = function(node, defVal) {  var retStr="";  if (!node) {    return (typeof defVal === 'undefined' || defVal === null) ? '' : defVal;  }   if(node.nodeType==3||node.nodeType==4||node.nodeType==2){      retStr+=node.nodeValue;   }else if(node.nodeType==1||node.nodeType==9||node.nodeType==11){      for(var i=0;i<node.childNodes.length;++i){         retStr+=arguments.callee(node.childNodes[i]);      }   }   return retStr;};
