[Zope] Easily including external HTML file?

[Alexander Staubo]

Afaik, Zope does not have any built-in document grabbing routines, but
it's real easy to do with httplib in an External Method. Something like:

import httplib

def GetLinuxToday():
  http = httplib.HTTP('linuxtoday.com')
  http.putrequest('GET', '/backend/lthead.inc')
  http.putheader('Accept', 'text/html')  # we can handle text/html
  http.putheader('Accept', 'text/plain')  # we can handle text/plain
  http.endheaders()
  httpcode, httpmsg, headers = http.getreply()  # get response headers
  if httpcode != 200:
    raise "Could not get document"  # HTTP error
  doc = http.getfile()
  data = doc.read()  # read file
  doc.close()
  return data

Didn't test this inside Zope, but it works standalone. Just put it in a
file in Zope's extensions directory (eg., c:\zope\extensions), add an
External Method, enter GetLinuxToday as id and function name, and call
it up in a document:

	<!--#var "GetLinuxToday()"-->

Hope this helps.
