Extract text from a file between two markers
A common approach to this is using a state machine that reads the text until the
<START> marker is encountered, then starts a “recording mode”, and extracts the text until the
<END> marker is encountered. This process can repeat if multiple sections may appear in the file and have to be extracted.
inRecordingMode = False for line in file: if not inRecordingMode: if line.startswith('<START>'): inRecordingMode = True elif line.startswith('<END>'): inRecordingMode = False else: yield line
For simple cases, this could also be solved with a regular expression.
