UPDATE: I've updated the code to look like this:

<div id="fitin">

<span id="Body0"></span>
</div>
<hr></hr>
<div id="slideshow">
   <div>
<p class="small">Post 5</p>
<span id="Body4"></span>
   </div>
   <div>
<p class="small">Post 2</p>
<span id="Body1"></span>
   </div>
   <div>
<p class="small">Post 3</p>
<span id="Body2"></span>
   </div>
   <div>
<p class="small">Post 4</p>
<span id="Body3"></span>
   </div>
</div>
</div>


<script>

if (window.XMLHttpRequest)
  {// code for IE7+, Firefox, Chrome, Opera, Safari
  xmlhttp=new XMLHttpRequest();
  }
else
  {// code for IE6, IE5
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
xmlhttp.open("GET","...=xml",false);
xmlhttp.send();
xmlDoc=xmlhttp.responseXML;

var i=0,d;
while (d=document.getElementById["Body"+i]) 
d.innerHTML=xmlDoc.getElementsByTagName("Body")[i++].childNodes
[0].nodeValue;

</script>

EDIT: It doesn't pull the same data that it was pulling before and no posts show up now. It's as if it's not gathering the array correctly (or posting it onto the page)
