Ajax problem in IE7 - get.get() is empty

Question

I am testing Ajax under Mozilla Firefox and IE7. Under Firefox is everything fine but IE7 gives me errors.
My process is the following:
declare
l_counter number;
l_o_name varchar2(2000);
begin
owa_util.mime_header('text/xml', FALSE );
htp.p('Cache-Control: no-cache');
htp.p('Pragma: no-cache');
owa_util.http_header_close;
htp.prn('<select>');
htp.prn('<option value="x">x</option>');
htp.prn('</select>');
debug.add('ok');
end;
debug_add('ok') adds text 'ok' into debugging table. I can see that this info is being inserted into the table, so the process runs through.
My JavaScript is in ApEx page attributes "HTML header" section and is like the following:
<script type="text/javascript">
function get_AJAX_SELECT_XML(pThis,pSelect){
     var l_Return = null;
     var l_Select = html_GetElement(pSelect);
     var get = new htmldb_Get(null,html_GetElement('pFlowId').value,'APPLICATION_PROCESS=my_proc',0);
     get.add('GTEST',pThis.value);
alert(get.get());
     gReturn = get.get('XML');
     if(gReturn && l_Select){
alert('Never here in IE7');
          var l_Count = gReturn.getElementsByTagName("option").length;
          l_Select.length = 0;
          for(var i=0;i<l_Count;i++){
               var l_Opt_Xml = gReturn.getElementsByTagName("option");
               appendToSelect(l_Select, l_Opt_Xml.getAttribute('value'), l_Opt_Xml.firstChild.nodeValue)
     get = null;
function appendToSelect(pSelect, pValue, pContent) {
var l_Opt = document.createElement("option");
l_Opt.value = pValue;
     if(document.all){/* why is ie different ask bill */
          pSelect.options.add(l_Opt);
          l_Opt.innerText = pContent;
     }else{
          l_Opt.appendChild(document.createTextNode(pContent));
          pSelect.appendChild(l_Opt);
</script>
alert(get.get()); gives me popup with text "undefined" in IE.
So "if(gReturn && l_Select)" will never become true.
I call it in an item:
onchange="get_AJAX_SELECT_XML(this,'P3201_XXX')"
In Mozilla 2.0.0.7 everything works, i can get correct answer from get.get() and the list is being filled with "x".

Hi,
I'm having a sporatic problem.
Where do you put the encoding?
Content-type: text/xml; charset=UTF-8
Cache-Control: no-cache
Pragma: no-cache
<?xml version="1.0" encoding="UTF-8"?>
I have the following in my ODP function
owa_util.mime_header('text/xml', FALSE );
htp.p('Cache-Control: no-cache');
htp.p('Pragma: no-cache');
owa_util.http_header_close;
then I start my select list:
     htp.prn('<select>');
     htp.prn(ls_default);
and a loop to build the option code
