That script's a bit old and doesn't do the extra className checking  
that I recommended yesterday. Also it's a different approach to  
George Hotelling's script as it picks out the microformat fragment  
and works on that, rather than passing the whole page off to an  
external processor. What you end up with is just the raw XML, rather  
than a processed hCard -> ICS conversion. However...

I have a Greasemonkey script at the moment which identifies a  
microcontent fragment, loads in an external XSLT file, processes the  
fragment and can then insert it back into the document/put it in a  
data URI, do whatever you want with it.  At the moment I'm trying to  
figure out how to make it not request the XSLT file from my server on  
every page view that contains a fragment, but it depends on  
Greasemonkey variable scoping which is changing too much this week.

The main point then is - what do you want to do with this data once  
you have extracted and processed it? POSTing it to a remote server is  
one idea, but then you could do the processing on the server anyway.  
I haven't really though of anything useful yet :-)
