Hi Maria,
This is not really an XSL related question so you may want to ask a more
suitable forum next time ;-)
XML islands are not really supported , nor should they IMHO. Elements
that start with 'xml' are not allowed by the XML spec, so using XML
islands in XHTML makes it invalid XML...
So...
There are many alternatives, such as loading the documents in a seperate
request or wrapping the XML in a comment and parsing that instead. Both
can easily be done in a crossbrowser way with a couple of if>else
branches or the sarissa library [1].
Finally, to answer your question and although I would advice not using
islands, you may [2] helpfull.

hth,
Manos

I am trying to create a single HTML file with an embedded XML island and two
embedded XSL stylesheets. The user would then be able to switch between
different views of the same data. This works well in IE, but I am having
trouble properly loading the XSL in Netscape. I know that the XML data is
being properly loaded because the code works in another context. It is the
embedded XSL that is not working in Netscape. How can I access the XSL in
Netscape?
