Mmmm... The above links and hints did teach more about the infamous
"blackslash plague", but I'm still stuck because all the examples
consider static strings, while I'm building it dynamically by
extracting data from a web page through the re module:

----------------------------------------------
import sys
import re

#1. Extract stuff between BODY tags
input = "<body>c:\temp</body>"
body = re.search('<body.*?>(.*?)</body>',input,re.IGNORECASE |
re.DOTALL)
if body:
	body = body.group(1)
print "Body = " + body

#2. Insert extracted stuff into template
output = "<body>here's the path: </body>"
output = re.sub('</body>', body + "</body>", output)
print output
----------------------------------------------

I also tried running this before so that the problem would go away,
but Python doesn't like it either:

body = re.sub(r'\',r'\\',input)

The script does run, but 
Fred.
