You can use the "display" attribute in CSS to control whether tags should display "inline" or in a separate "block".
If you want to start playing with the layout more, it is best to separate the elements, for example:
code:


function nodeToObject(n:XMLNode):Object {

 var o:Object = new Object();

 for (var i in n.childNodes) {

  o[n.childNodes[i].nodeName] = n.childNodes[i].firstChild.nodeValue;

 }

 return o;

}

newsContent.onLoad = function(success)

{

 if (success) {

  var ns:Array = this.firstChild.firstChild.childNodes;

  var s:String = "";

  for( var i=0;i<ns.length;i++ ) {

   var newsItem:Object = nodeToObject(ns[i]);

   s += "<entryDate>News item number "+(i+1)+" published on "+newsItem.entryDate+"</entryDate>";

   s += "<entrytitle>"+newsItem.entryTitle+"</entrytitle>";

   s += "<entrybody>"+newsItem.entryBody+"</entrybody>";

   if((i+1) < ns.length) s += "<BR />______ ----- @@@@</BR>";

  }

 }

 newsText.htmlText = s;

}
