Does the text "TREES" and "END TREES" actually have quotes? If not, leave them out of the pattern, because they won’t match.
The other thing is that the ? is a modifier, it must have some particular character or set of characters immediately before it, rather than another pattern like .* , which matches anything. So you should just leave ? out of it.

Good morning all,
Not quite a GIS question, but since you all have proven to be so, so smart in the past, I figured I’d ask here anyways….
I am trying to write a Python script that isolates a block of text within a text file. I want to manipulate the data within that block, but first I need to isolate it.
My research told me to try using something like re.compile and re.search to do so but I haven’t been having much luck. I had this block of code:
import os, re
file = open("200214092341eriswor_1_56.txt", "r")
s = file.read()
r = re.compile('"TREES"(.*?)"END TREES"')
m = r.search(s)
if m:
trees = m.group(1)
print trees
But it isn’t returning anything and if I print m it returns “None”.
The data in the text file is separated out my commas, and the words “TREES” and “END TREES” and on their own lines above and below the block I’d like to isolate.
Any thoughts?
Kind regards,
