正則表達式（Python）數據提取 - 重疊或不完整的結果

Question

我試圖從我已經從PDF轉換爲Python石板庫文本的一些世衛組織代碼簿中提取數據。

我想打2個數字，破折號，2位，其次是一些文字開始，以「Q」 +1位或2位，並再次「Q」結尾的文本+1位或2位

17-17How old are you?Q1Q1 
31-31During the past 30 days, how many times per day did you usually eat fruit, such as bananas, apples, oranges, dates, or any other fruits?Q7Q11 

有時，這些短語的結束與一個空白，有時接下來的問題會立即開始（這裏有三個問題），觀察Q4Q424-29和Q5Q530-30

20-23How tall are you without your shoes on? (Note: Data are in meters.)Q4Q424-29How much do you weigh without your shoes on? (Note: Data are in kilograms.)Q5Q530-30During the past 30 days, how often did you go hungry because there was not enough food in your home?Q6Q7 

隨着

\d{2}-\d{2}[a-zA-Z0-9 .()?:,]+Q\d{1,2}Q\d(\d)*? 

我非常接近，但當第二個「Q」有兩位數字時，我錯過了第二個數字。

我試圖添加一個負前瞻

\d{2}-\d{2}[a-zA-Z0-9 .()?:,]+Q\d{1,2}Q\d((\d)(?!\d\d-)) 

排除有兩位數字，破折號模式的開始。

\d{2}-\d{2}[a-zA-Z0-9 .()?:,]+Q\d{1,2}Q\d{1,2} 

包括「Q」的第二個數字但產生重疊的結果，例如，在Q4Q424-29，第一個字符串以Q4Q42結尾，第二個字符串以4-29開頭。

與原樣品的文字部分的正則表達式是在這裏：https://regex101.com/r/d9Dlga/2/

任何建議，誰提取出正確的字符串，如：

17-17How old are you?Q1Q1 
20-23How tall are you without your shoes on? (Note: Data are in meters.)Q4Q4 
24-29How much do you weigh without your shoes on? (Note: Data are in kilograms.)Q5Q5 
31-31During the past 30 days, how many times per day did you usually eat fruit, such as bananas, apples, oranges, dates, or any other fruits?Q7Q11 

謝謝！

Answer 1

我現在看到的問題。我認爲作品的新嘗試：

\d{2}-\d{2}.+?Q\d{1,2}Q\d{1,2}(?!\d-\d{2})

我把負先行在年底進行測試，如果一個新的部分已經開始。

• 9場比賽
• 正確抓住全2位數的結局

Answer 2

以下模式應該工作：

\d{2}-\d{2}[a-zA-Z0-9 .()?:,]+Q\d{1,2}Q\d(\d(?!\d-))?
