My XSLT solution works on Firefox, not in IE

[Peter Laman]

Hello,

A webserver I'm writing is accessed both by "browser clients" for
interactive use and by "program clients" that request XML formatted
data. To streamline error handling, the server always returns errors
in XML format, linked to an XSLT stylesheet for browser display. This
way both browsers and programs can be served error messages the same
way.

One of these error content is as follows:

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="http://notepeter/pow/
protecs.dll/doc?ref=Exception.xsl&fld=tpl"?>
<powxml
generator="Protecs On The Web"
fileversion="4.0"
powurl="http://notepeter/pow/protecs.dll">
<exception
message="Invalid use of keyword.
Token:
%&quot;
ORDER
Line Number: 3Aanvullende informatie over BDE
fout: "
dbierr="$2A12 (Invalid use of keyword.)"
bdetable="N.V.T."
processid="0x000005B0 (Decimaal: 1456)"/>
</powxml>

Firefox handles this perfectly, the linked stylesheet is used to
render the data in XHTML format. However, Internet Explorer 6.0 simply
displays the raw XML tree. Further investigation on the server side
shows that it doesn't even request the stylesheet. However if I
request the stylesheet by entering its URL (http://notepeter/pow/
protecs.dll/doc?ref=Exception.xsl&fld=tpl) on the address bar, it
shows up. So the URL is accessible. The question is: why doesn't IE
even request the stylesheet?

Is the XML document also served from http://notepeter/?

I believe IE is objecting to the ampersand in the URL. Although XML 1.0
permits ampersands to appear in processing instructions, <URL:
http://www.w3.org/TR/xml-stylesheet> says you must use '&amp;' in that
particular processing instruction.

Thanks. That fixed it for IE,... But Firefox doesn't accept it. I've
changed the URI needed to get the stylesheet in order to make it
acceptable by all browsers and it works now.

the '&amp;', so I've simply changed the URL needed to get the
stylesheet to one that packs all info in a single field.

You're right. There's a bug <URL:
https://bugzilla.mozilla.org/show_bug.cgi?id=286132>, which, happily, is
fixed in version 3.0.
