MSXML ie4.0

Anyone know if you can parse XML islands with the IXMLDocument interface?  If so can you pass along a sample parseable statement?  thanks

IE4 doesn't support data islands. IE5 does.

See the xml_data_islands sample that comes with the MSDN IE5 Workshop.

The following sample is in the MSDN Library that comes with Visual Studio 6.0.

I have it parsing standard XML fine.  I just need to know if anyone has gotten it to work with XML islands.  An island is an embedded XML snippet in the body of an HTML Document.  I therefore want to be able to point the IXMLDocument pointer to the URL and have it dissect the XML island from the innards of a HTML page.
