How to open a link by clicking on a DataGrid row

Question

I have a list of documents that are accessible over the internet.  The list is in an XML file which serves as the data source for a DataGrid.  What I cannot figure out is how to open the document selected in the DataGrid.  I think that I need to change something in the openDocument function (below) but I am not certain what I should change.  Any help would be appeciated.
Sample file are below:
Application
viewDocuments.mxml
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
layout="absolute"
creationComplete="initApp();">
<mx:Script>
<![CDATA[
import mx.collections.ArrayCollection;
import mx.rpc.events.ResultEvent;
import mx.core.Application;
[Bindable]
private var documents:ArrayCollection;
private function initApp():void
this.srv.send();
private function onResult(evt:ResultEvent):void
this.documents=evt.result.data.document;
private function openDocument():void
var docURL:String;
docURL=dgDocuments.selectedItem.url;
navigateToURL(new URLRequest("http://cnn.com/"), "_blank");
//Below does not work
//navigateToURL(new URLRequest("docURL"), "_blank");
]]>
</mx:Script>
<mx:HTTPService id="srv"
url="documents.xml"
resultFormat="object"
result="onResult(event)"/>
<mx:Canvas id="cViewDocumentsContainer"
x="0"
y="0"
width="100%"
height="100%">
<mx:DataGrid id="dgDocuments"

dataProvider="{documents}"

y="74"
doubleClickEnabled="true"
doubleClick="openDocument();">

dataField="doc_id"

<mx:DataGridColumn headerText="Name"

<mx:DataGridColumn headerText="File Name"

<mx:Text x="15"
y="48"
text="Double-click on the document below you want to read. The document will open in a new window."/>
</mx:Canvas>
</mx:Application>
Data

You need this (removed double quotes):
navigateToURL(
new URLRequest(docURL), "_blank");
