[R] Extract Data from a Webpage

[Chuck Cleland]

Hi All:
  I would like to extract the provider name, address, and phone number
from multiple webpages like this:

http://oasasapps.oasas.state.ny.us/portal/pls/portal/oasasrep.providersearch.take_to_rpt?P1=3489&P2=11490

  Based on searching R-help archives, it seems like the XML package
might have something useful for this task.  I can load the XML package
and supply the url as an argument to htmlTreeParse(), but I don't know
how to go from there.

thanks,

Chuck Cleland
