Question

This is Part 2 of this question and thanks very much for David’s answer. What if I need to extract dates which are bounded by two keywords?

Example:

text = "One 09 Jun 2011 Two 10 Dec 2012 Three 15 Jan 2015 End"

Case 1 bounding keyboards: "One" and "Three"
Result expected: ['09 Jun 2011', '10 Dec 2012']

Case 2 bounding keyboards: "Two" and "End"
Result expected: ['10 Dec 2012', '15 Jan 2015']

Thanks!

Answer 1

You can do this with two regular expressions. One regex gets the text between the two keywords. The other regex extracts the dates.

match = re.search(r"\bOne\b(.*?)\bThree\b", text, re.DOTALL)
if match:
    betweenwords = match.group(1)
    dates = re.findall(r'\d\d (?:Jan|Feb|Mar|Apr|May|Jun|Jul|Aug|Sep|Oct|Nov|Dec) \d{4}', betweenwords)
