How do i get these links to open in a new/blank window (xml)

1

i found this code somewhere, and have used it for a site, but the links open on the same page and i cant find an option to have them open in a different target window.

AS code:

// The first step is to activate the XML object
headlineXML = new XML();
/*
With the XML Object now active you must now load an XML foramtted document.
Any DTD or XLS formatting will be ignored.
*/
headlineXML.onLoad = myLoad;
headlineXML.load("links.xml");
// Before proceeding to far into the program, make sure the XML document has loaded
// Extract information from the XML file
function myLoad(ok) {
 if (ok == true) {
  Publish(this.firstChild);
 }
}
function Publish(HeadlineXMLNode) {
 if (HeadlineXMLNode.nodeName.toUpperCase() == "BROADCAST") {
  content = "";
  story = HeadlineXMLNode.firstChild;
  while (story != null) {
   if (story.nodeName.toUpperCase() == "STORY") {
    lead = "";
    body = "";
    URL = "";
    element = story.firstChild;
    while (element != null) {
     if (element.nodeName.toUpperCase() == "LEAD") {
      lead = element.firstChild.nodeValue;
     }
     if (element.nodeName.toUpperCase() == "BODY") {
      body = element.firstChild.nodeValue;
     }
     if (element.nodeName.toUpperCase() == "URL") {
      URL = element.firstChild.nodeValue;
     }
     element = element.nextSibling;
    }
    content += "<font size='+2' color='#DA0078'><a href='"+URL+"'>"+lead+"</a></font><br>"+body+"<br><br>";
    txt.htmltext=content;
   }
   story = story.nextSibling;
  }
 }
}

XML code:

<broadcast>
<story>
<lead>This is Headline 1</lead>
<body>This is where you can add content that will appear under the first headline</body>
<URL>http://www.communitymx.com/</URL>
</story>
<story>
<lead>This is Headline 2</lead>
<body>This is content that can appear under the second headline.</body>
<URL>http://www.flash-remoting.com/</URL></story>
<story>
<lead>This is Headline 3</lead>
<body>This is content that can appear under the third headline.</body>
<URL>http://www.macromedia.com/</URL>
</story>
</broadcast>

thanks.
