python - How to replace a specific line in a file?

Question

I have 2 xlf files, one correct (in French) and one with some errors in some tags (in English). I have to take tags in the french file, and then replace matching tags content in the english file. The problem here is that theese files don't have the same line number.

From what I have down here, I managed to make the matching but I didn't succeeded on replacing the text in the english file.

Here is my code :

import re
pattern = re.compile('(?<=<x).*?(?=/>)')
fin = open("French.xlf")
fout = open("English.xlf", 'r')
matches = []

for line in fin:
    matches.extend(re.findall(pattern, line))

for line in fout:
    for i, match in enumerate(pattern.findall(line)):
        newLine = line.replace(match, matches[i])
        print(pattern.findall(line))
        print(match," to ", matches[i])
        print(newLine)

fin.close()
fout.close()
