    copied!<p>I am writing a page that uses javascript to load an xml file from the server, and then I parse it. My code runs correctly in Firefox, Chrome, and IE10, but in IE9 the childNodes array of the responseXML object has only 1 item that says "Invalid number of parameters". I know the xml loads correctly because the firstChild property has the correct name and value, and its firstChild property does also, etc. </p> <p>I could rewrite my parsing code to work with this, but I dont really want to do that for a number of reasons. </p> <p>Does anyone have any ideas what my problem is here? I also noticed that the dataType and doctype properties of the responseXML object are null. </p> <p>I checked the http header the server is sending back when the xml file is requested, and it has Content-Type: text/xml. </p> <p>This is my code that is causing the problem,</p> <pre><code>var xmlReq = new XMLHttpRequest(); xmlReq.addEventListener("load", onXmlReqComplete, false); xmlReq.addEventListener("error", onXmlReqError, false); xmlReq.addEventListener("abort", onXmlReqAbort, false); xmlReq.open("get", "tree.xml", true); xmlReq.send(); function onXmlReqComplete(e){ var xmlResp = this.responseXML; //this is the line that causes the error, //SCRIPT5007: Unable to get property 'childNodes' of undefined or null reference var items = xmlResp.childNodes[0].childNodes[1].childNodes; for(var i = 0; i &lt; items.length; i++){ if(items[i].nodeName == "#text"){ continue; } treeData.push(items[i]); } layoutDisplay(); } </code></pre> <p>Any help is appreciated, thank you</p>
