[SOLVED] Read text file from some point till EOF?

[Winfried]

Hello,

I need to jump to a given string in a text file, and grab everything from that point to the end of the file for further processing using a regex.

I'm not sure why Python isn't happy:

with open(INPUTFILE,encoding="utf-8") as reader:
	content = reader.read()

content = re.search(content,'^SessionData.+',re.MULTILINE|re.DOTALL)

c:\temp>list.files.py
Traceback (most recent call last):
  File "C:\list.files.py", line 10, in <module>
    content = re.search(content,'^SessionData.+',re.MULTILINE|re.DOTALL)
  File "C:\Python38-32\lib\re.py", line 201, in search
    return _compile(pattern, flags).search(string)
  File "C:\Python38-32\lib\re.py", line 304, in _compile
    p = sre_compile.compile(pattern, flags)
  File "C:\Python38-32\lib\sre_compile.py", line 764, in compile
    p = sre_parse.parse(p, flags)
  File "C:\Python38-32\lib\sre_parse.py", line 948, in parse
    p = _parse_sub(source, state, flags & SRE_FLAG_VERBOSE, 0)
  File "C:\Python38-32\lib\sre_parse.py", line 443, in _parse_sub
    itemsappend(_parse(source, state, verbose, nested + 1,
  File "C:\Python38-32\lib\sre_parse.py", line 554, in _parse
    code1 = _class_escape(source, this)
  File "C:\Python38-32\lib\sre_parse.py", line 349, in _class_escape
    raise source.error('bad escape %s' % escape, len(escape))
re.error: bad escape \T at position 1494 (line 76, column 27)

Here's an example of what is found in the intput file:

FilePath = C:\Temp\SomeFile.txt

Is it because Python interprets \T as a wrongly formated tab sequence?

I've also tried to open the file in binary mode, but get the same error:

with open(INPUTFILE,"rb") as reader:

What would be the right way to extract part of a file for further parsing?

Thank you.

Found it:

import re

INPUTFILE = "whole.txt"
with open(INPUTFILE,encoding="utf-8") as reader:
	content = reader.read()

subset= content[content.index("SessionData"):]

#Don't use ^ and $!
files = re.findall(r'FilePath = (.+)', subset)
for file in files:
	print(file)
