Error in outputting xml formatted data

Question

Hello,
I'm trying to output xml formatted data using apex.
At about 70% into the formatted output I get this in the browser:
  <descript>punct= & > < /,() &</descript>
  </row>
- <row The XML page cannot be displayed
Cannot view XML input using XSL style sheet. Please correct the error and then click the Refresh button, or try again later.
Only one top level element is allowed in an XML document. Error processing resource 'http://apex.oracle.com/pls/otn/f?p=158...
<script language="JavaScript1.1" type="text/javascript">
-^
m">>
<DIVI have a 600 row table (dml below) with identical string in each row of the descript column. (I put in some special characters just to push it through the escape function for html. It is displaying the text correctly.)
The page has one report region (plsql below).
The page template is stripped down.
My local results are identical to the otn hosted workspace.
I did dump the table in xml format and displayed the dump file in browser without a problem, so I'm missing something in the code.
Thank you.

May be it helps you. I use SQL/XML and APEX Application Process to generate XML succesfully
Here is the result:
http://htmldb.oracle.com/pls/otn/f?p=9774:101:0:APPLICATION_PROCESS=RSSNEWEVENTS
and here is the Process Text source:
declare
a clob;
begin
owa_util.mime_header( ccontent_type => 'text/xml', bclose_header => TRUE, ccharset => 'utf-8');
htp.prn('<?xml version="1.0" encoding="UTF-8"?>');
select
XMLTYPE.getStringVal(
XMLElement("rss",
XMLAttributes('2.0' as version),
XMLElement("channel",
XMLConcat(
XMLElement("title",'iActiveLife - novinky'),
XMLElement("link",'http://www.iactivelife.cz/'),
XMLElement("description",'iActiveLife - Zajímavý život snadn&#283;ji'),
XMLElement("language",'cs'),
XMLElement("pubdate",''),
XMLAgg(
XMLElement("item",
XMLConcat(
XMLElement("title",event_name),
XMLElement("link",'http://htmldb.oracle.com/pls/otn/f?p=' || v('APP_ID') || ':37:' || v('SESSION') || '::NO::P37_EVENT_ID:' || event_id),
XMLElement("description",'')
) into a
from (
select event_id,event_name,issue_date, last_update_order
from (
select events.event_id, events.event_name, events.issue_date, rank () over (order by events.issue_date desc) as last_update_order
from events
where exists ( select * from opportunities where events.event_id=opportunities.event_id and opportunities.user_id is not null)
order by events.issue_date desc)
where last_update_order<=10
htp.prn(a);
end;
