Output with line breaks seemingly randomly placed

Question

Hola -
I've adapted Tyler Muth's RSS feed article (http://tylermuth.wordpress.com/2008/01/22/producing-rss-from-plsql/) for the most part successfully; however, my output has breaks in the lines at inappropriate places, often in the mddle of an XML element tag for example. The placement of the breaks varies if I change the values of l_idx, l_len, l_defrows, l_maxrows, and l_desclen, but the breaks persist. They're not reflected in the code below but I've added the utl_file.fflush to no good effect.
Examples of broken output:
<pre>
<title>Three
prehistoric inventions that shaped us /</title>
<guid
isPermaLink="false">226402455778123622</guid>
<pubDate>Thu, 04 Aug 2011 12:36:22
EST</pubDate>
<guid isPermaLink="fal
se">220922455778123622</guid>
<item
>
</pre>
It's a lot of data so I won't post it here, but here's the code & the table; any ideas as to where to start investigating will be greatly appreciated.
Code:
create or replace
PROCEDURE "RSSLOOP3" ( fund_in IN VARCHAR2, fund_in2 IN VARCHAR2 := 'XXX')
is
-- customizable parameters
l_title varchar2(255) := ' New Titles Since ' || to_char(sysdate - 90, 'MM/DD/YYYY');
l_link varchar2(255) := 'replace this' || fund_in || '.rss';
l_description varchar2(255) := 'This is a feed of changes to items ' || fund_in;
l_language varchar2(255) := 'en-us';
-- end customizable parameters
l_version varchar2(10) := '2.0';
l_clob clob;
l_idx pls_integer := 1;
l_len pls_integer := 255;
l_defrows pls_integer := 100;
l_maxrows pls_integer := 100;
l_desclen pls_integer := 250;
-- for output to file
fh UTL_FILE.FILE_TYPE;
path VARCHAR2(30);
filename VARCHAR2(30);
begin
path := '/http/live/screens/rss/';
filename := fund_in || '.rss';
fh := UTL_FILE.FOPEN(path, filename, 'w');
for i in (
select xmlelement( "rss",
-- Begin XML Header Block
xmlattributes( l_version as "version"),
xmlelement( "channel",
xmlforest( l_title as "title",
l_link as "link",
l_description as "description",
l_language as "language"),
-- End XML Header Block
-- Begin List of Individual Articles or Items
xmlagg(
xmlelement( "item",
xmlelement("title", x.title),
xmlelement("link", x.link),
xmlelement("description", convert(x.description, 'UTF8', 'AL32UTF8')),
xmlelement("callnum", x.callnum),
xmlelement("pubDate", to_char(x.updated_on,'Dy, DD Mon RRRR hh24:mi:ss')),
xmlelement("guid", XMLATTRIBUTES('false' as "isPermaLink"),x.id||to_char(x.updated_on,'JHH24MISS'))
-- End List of Individual Articles or Items
) as result
from ( -- Actual Database Query that populates the list of Items
select id,title,link,description,updated_on, callnum
from drx_rss_feeds
where (fund like fund_in||'%')
and rownum < (l_maxrows+1)) x)
loop
l_clob := xmltype.extract(i.result,'/').getclobval;
exit;
end loop; --i
--- OUTPUT RESULTS
for i in 1..ceil(dbms_lob.getlength(l_clob)/l_len) loop
UTL_FILE.PUT_LINE(fh,(substr(l_clob,l_idx,l_len)));
l_idx := l_idx + l_len;
end loop; --i
UTL_FILE.FCLOSE(fh);
end rssloop3;
Table:
CREATE TABLE "DRX_RSS_FEEDS"
"ID" VARCHAR2(32 BYTE),
"TITLE" VARCHAR2(255 BYTE),
"DESCRIPTION" VARCHAR2(4000 BYTE),
"LINK" VARCHAR2(1000 BYTE),

Or have a look at the Oracle Documentation, for instance at the parameters for utl_file.fopen
max_linesize Maximum number of characters for each line, including the
newline character, for this file (minimum value 1, maximum
value 32767). If unspecified, Oracle supplies a default value of
1024.It wouldn't surprise me if your randomly placed line breaks are all 1023 characters a part.
