Please note that if the rss feed is version 2.01 or earlier Mathematica
version 7 has been supporting direct Import and conversion to NoteBook
bject.

The following will open a new Notebook with the ability to refresh
Import["http://feeds.bbci.co.uk/news/world/europe/rss.xml";, {"RSS", 
  "NotebookObject"}]

The following will return a Notebook symbol with Cell data
Import["http://feeds.bbci.co.uk/news/world/europe/rss.xml";, "RSS" ]
At which point the pattern matching would not be based on "XML" but
Mathematica Notebook structure.

Hi Sjoerd,

Thank you for your tips!  This is exactly the type of thing that I need 
to get me going.  I figured Import was the thing to use, but I'm still 
a bit green on specifying patterns for Cases.  Your example here will 
give me a good start.

Thanks again,

Gregory Lypny
