regular expression error ?

[Lance Hoffmeyer]

why isn't re.search recognizing "file"?  I can print the contents of "file".


import win32com.client
import re

D=MSWord.Documents.Open('C:/test/Test.doc')
file=D.Content
print file

match = re.search('(Table ?)', file)
if match:
   print "Table Number is: ", match.group(1)


Traceback (most recent call last):
  File "test.py", line 21, in ?
    match = re.search('(Table ?)', file)
  File "C:\Python24\Lib\sre.py", line 134, in search
    return _compile(pattern, flags).search(string)
TypeError: expected string or buffer
