Javascript iframe or div?

[terme22]

Is it possible to response .write to a div or iframe so that my page doesn't get written over?
here is the code:

<form name="list"  action="">
	<select name="listGen" onchange="xmlConnect()" size="1">
	  <option value="0">please choose</option>
	  <option value="1">sales</option>
	  <option value="2">IT</option>
	  <option value="3">Human Resources</option>
	  <option value="4">Front Office</option>
	</select>
</form>
<script type="text/javascript">

function xmlConnect()
{
		 var x = document.forms['list'].elements['listGen'];
		 var thevalue = x.options[x.selectedIndex].value;
		 document.write(thevalue);
		 xmlDoc=loadXMLDoc("../bin/people.xml");
    
    x=xmlDoc.getElementsByTagName("fname");
    y=xmlDoc.getElementsByTagName("lname");
    z=xmlDoc.getElementsByTagName("personal");
    a=xmlDoc.getElementsByTagName("department");
    
   
    for (i=0;i<x.length;i++)
      { if (a[i].childNodes[0].nodeValue == thevalue)
            {
              document.write(x[i].childNodes[0].nodeValue);
              document.write(" ");
              document.write(y[i].childNodes[0].nodeValue);
              document.write(": ");
              
              document.write(z[i].childNodes[0].nodeValue);
              document.write("<br />");
              document.write("<br />");
            }
     }
