Hello, I am trying to save a dynamically created anchor's id onclick, but I am having a lot of trouble.

Code:
<!DOCTYPE HTML>
<html>
<head>
<meta charset="utf-8">
<title>Untitled Document</title>
<style>
</style>
</head>

<body onload="initAll();">
<div id="test"></div>

<script type="text/javascript">
var xhr = false;			//global xhr variable
var allRequestIds = new Array();
var allRequestDates = new Array();
var allRequestNames = new Array();
var allRequestBriefs = new Array();
var allListLinks = new Array();
var allListItems = new Array();
var linkId;       //global variable for clicked link's id; set to be the same as xml data's id; used to pull more data in next page


function initAll(){
	if (window.XMLHttpRequest){		//initialize xmlhttprequest into xhr variable
	xhr = new XMLHttpRequest();
	}
	else{}//ie stuff goes here
	xhr.open("GET","xml/request.xml",true);		//open connection
	xhr.onreadystatechange=createLinks;				//onreadystatechange call createLinks()
	xhr.send(null);	
}

function createLinks(){
	if(xhr.readyState==4){
		if(xhr.status==200){
			if(xhr.responseXML){
				var allRequests=xhr.responseXML.getElementsByTagName("request");		//save all requests into array
				var newList=document.createElement("ol");                               //create a new ordered list
				for(i=0;i<allRequests.length;i++){                        //arrays of each tag, and an array of links
					allRequestIds[i]=allRequests[i].getElementsByTagName("requestId")[0].firstChild.nodeValue;
					allRequestDates[i]=allRequests[i].getElementsByTagName("date")[0].firstChild.nodeValue;
					allRequestNames[i]=allRequests[i].getElementsByTagName("name")[0].firstChild.nodeValue;
					allRequestBriefs[i]=allRequests[i].getElementsByTagName("brief")[0].firstChild.nodeValue;
					allListLinks[i]=document.createElement("a");            //create an array of links
					allListLinks[i].appendChild(document.createTextNode(""+allRequestDates[i]+" "+allRequestNames[i]+" "+allRequestBriefs[i]+""));    //i don't know how to add a new line within createtextnode!!! wtf?! i wanted to add a <br />
					allListLinks[i].setAttribute("href","somepage.html");
					allListLinks[i].setAttribute("class","dynamicLink");		
					allListLinks[i].setAttribute("onclick","pullDetailed();");
					allListItems[i]=document.createElement("li");             //create an array of list items
					allListItems[i].appendChild(allListLinks[i]);  //append each anchor into each list item
					newList.appendChild(allListItems[i]);          //append all list items into ordered list
				}
				document.getElementById("test").appendChild(newList);      //append list into test paragraph
				
			}
		}
	}
}

function pullDetailed(){
	alert("function pullDetailed called!");	//this is just testing to see if this function has been called on anchor click
	linkId=this.innerHTML.;	//this doesn't work
	alert(linkId);
}
</script>
</body>
</html>
