// So, given a syndication script with a fixed ID:
<script type="text/javascript" id="syndication" src="syndication.js"></script> 

// We can go from oldskool nastiness like this:
document.write('<p id="syndicated-content">Here is some syndicated content.</p>'); 

// To modern loveliness like this:

var newcontent = document.createElement('p'); 
newcontent.id = 'syndicated-content'; 
newcontent.appendChild(document.createTextNode('Here is some syndicated content.')); 
var scr = document.getElementById('syndication'); 
scr.parentNode.insertBefore(newcontent, scr); 

// We could even go a step further and remove the <script> ID, but in that case we would need a concrete method for identifying the specific element. We could do that by knowing its SRC:

var scripts = document.getElementsByTagName('script'); 
for(var i=0; i<scripts.length; i++) 
{ 
  if(scripts[i].src == 'http://www.mydomain.com/syndication.js') 
  { 
    //scripts[i] is the one 
    break; 
  } 
}
