Hello...I've been trying to figure out this problem for most of the week - it's my second attempt at any XML and my first at XSLT so I haven't got a complete grasp of what I'm doing yet. Any help will be muchly appreciated. :)

The problem is, the code below validates and works in IE7 (obviously with their pre-set stylesheet). In IE6 the text describing the feed from the XSL file displays, but none of the actual news items between the <entry> tags of the XML file do i.e. the whole point of having the feed!

There is a way it DOES work in IE6 and Firefox 1.5, but doesn't work in IE7 (I'll explain below the code).

news-test.asp (generated with ASP and with company info removed):

<?xml version="1.0" encoding="ISO-8859-1"?>
<?xml-stylesheet type="text/xsl" href="news-feed.xsl"?>
<feed xmlns:atom="http://www.w3.org/2005/Atom">

It works in IE6 and Firefox but DOESN'T display in IE7 ("internet explorer does not support this feed format") if I change the namespace declaration from <feed xmlns="http://www.w3.org/2005/Atom"> to <feed xmlns:atom="http://www.w3.org/2005/Atom"> or infact if I add any bit of random text like :aaaaaaaargh there

Thanks for looking.

Solved! And just incase this might help anyone in future, here is the solution from Jeni and her XML pages at www.jenitennison.com

The use of the default namespace in the Atom feed means that the <feed>, <entry> etc. elements are in the Atom namespace.

In your stylesheet, you’re doing:

<xsl:for-each select="feed/entry">
...
</xsl:for-each>
When you select elements in XSLT, if you don’t give a prefix for the element then the processor will only look for elements in no namespace. So in this case you’re selecting <feed> elements in no namespace and their <entry> element children (in no namespace again).

You already have the Atom namespace declared in the stylesheet with the prefix atom. The solution is simply to use that prefix whenever you refer to an Atom element:

<xsl:for-each select="atom:feed/atom:entry">
...
</xsl:for-each>
