XMLDataSet works in FF and IE7, not IE6

Question

So on our website we've got a page with a Spry tabbed panel.
Two of the four panels load a Spry XMLDataSet. Both datasets are
being generated from a standard RSS feed. Everything works fine in
IE7 and FireFox, but in IE6, we get the spry:state=error. An
example of the code:
var dsHeadlines_filter = function(dataSet, row, rowNumber) {
row["link"] = Url.decode(row["link"]);
return row;
var dsPressReleases_filter = function(dataSet, row,
rowNumber) {
// row["link"] = Url.decode(row["link"]);
row["link"] = "
http://www.chaminade.edu/news/pr/rss.php?"
+ Url.decode(row["link"]);
row["link"] =
row["link"].replace(/CustomDispForm.aspx/,"rss_news.aspx");
var item_date = new Date(row["pubDate"]);
var today = new Date();
var one_day=1000*60*60*24;
if
(Math.ceil((today.getTime()-item_date.getTime())/(one_day)) >
60)
return null;
else
return row;
var dsHeadlines = new Spry.Data.XMLDataSet("
http://www.chaminade.edu/includes/rss.php?http://news.google.com/news??svnum=10&as_scoring =n&hl=en&tab=wn&ie=UTF-8&ned=us&as_drrb=q&as_qdr=&as_mind=18&as_minm=1&as_maxd=17&as_maxm= 2&geo=&aq=f&q=%22chaminade+university%22&output=rss",
"rss/channel/item",{sortOnLoad:"pubDate",sortOrderOnLoad:"descending",useCache:false});
dsHeadlines.setColumnType("pubDate", "date");
dsHeadlines.filterData(dsHeadlines_filter);
var dsPressReleases = new Spry.Data.XMLDataSet("
http://www.chaminade.edu/includes/rss.php?https://portal.chaminade.edu/_layouts/listfeed.a spx?List=%7B88741681%2D7558%2D4BF3%2DA377%2DBC59EB62B903%7D",
"rss/channel/item",{sortOnLoad:"pubDate",sortOrderOnLoad:"descending",useCache:false});
dsPressReleases.setColumnType("pubDate", "date");
dsPressReleases.filterData(dsPressReleases_filter);
Does anyone have an idea of why this isn't working in IE6?
IE6 doesn't even report any error messages. It simply shows the
HTML we setup upon a spry:state=error condition.

Yep, it was definately a content-type issue. Thanks for the
tip! My PHP/RSS parser was inadvertently setting the content type
back to text/html. I was able to override the function and set it
to text/xml, and it works great in all browsers including IE6.
Thanks again!
