StopIteration error before reading the text file using next()
I created this code to scan my samples_vsdt.txt
getting a certain values then writing it in a csv, I'm having an error StopIteration
and doesn't even read the text file. I'm trying to solve this for hours, any idea what's causing the problem?
Here is how my code works, Example this line:
Scanning samples_extracted82e5b144cb5f1c10629e72fc1291f535db7b0b40->(Word 2003 XML Document 1003-1)

82e5b144cb5f1c10629e72fc1291f535db7b0b40,Word 2003 XML Document 1003-1
Here is my code, and this is working for all my txt_files but this one sample_vsdt.txt doesn't work properly
import csv,re
out_vsdt = "samples_vsdt.txt"
out_sha1_vsdt = "sha1_vsdt.csv"

An alternative approach could be to just use a regular expression to extract whole blocks:
import csv
import re
out_vsdt = "samples_vsdt.txt"
out_sha1_vsdt = "sha1_vsdt.csv"
with open(out_vsdt) as f_input:
vscan32 = f_input.read()
with open(out_sha1_vsdt, 'w', newline='') as f_output:
csv_output = csv.writer(f_output)
csv_output.writerow(['SHA-1', 'VSDT', 'DESC'])
for sha, desc, vsdt in re.findall(r'Scanning.*?\([0-9a-f]+)(.*?)->((.*?))$', vscan32, re.S + re.M):
desc = '|'.join(line.strip() for line in desc.splitlines() if len(line.strip()))
desc = ''.join(filter(lambda x: x in string.printable, desc)) # remove non-printable characters
csv_output.writerow([sha, vsdt, desc])
This uses a multi-line expression that looks for blocks starting with Scanning
. Where there are multiple lines, the lines are stripped and joined together using a |
. Finally any non-printable characters are removed from the description.
This would give you an output starting something like:
SHA-1,VSDT,DESC
