如何在漂亮的湯對象中打印兩個短語之間的所有行？

Question

我有一個 html 文檔轉換成一個湯對象，我試圖打印兩個關鍵短語之間的所有文本行。 我正在使用soup.find 來搜索這兩個短語，但我不知道如何打印它們之間的所有行。 到目前為止，這是我的代碼：

file = open(r'PDFs/murrumbidgee/Murrumbidgee Unregulated River Water Sources 2012_20200815.html', 'r', encoding='utf8')

contents = file.read()

soup = BS(contents, 'lxml')

textStart = soup.find(text=re.compile("19  domestic and stock rights"))
textEnd = soup.find(text = re.compile('20  native title rights'))

print(textStart)
print(textEnd)

html的一個例子在這里：

 <br></span></div><div style="position:absolute; border: textbox 1px solid; writing-mode:lr-tb; left:72px; top:22061px; width:169px; height:11px;"><span style="font-family: Arial-BoldMT; font-size:11px">19  Domestic and stock rights 
<br>unsuitable for human consumption. Water from these water sources should not be 

<br>consumed without first being tested and if necessary, appropriately treated. Such testing 
<br>and treatment is the responsibility of the water user.

Answer 1

您可以使用re模塊來提取文本。 例如：

import re
from bs4 import BeautifulSoup


txt = '''
<br></span></div><div style="position:absolute; border: textbox 1px solid; writing-mode:lr-tb; left:72px; top:22061px; width:169px; height:11px;"><span style="font-family: Arial-BoldMT; font-size:11px">19  Domestic and stock rights
<br>unsuitable for human consumption. Water from these water sources should not be

<br>consumed without first being tested and if necessary, appropriately treated. Such testing
<br>and treatment is the responsibility of the water user.
<br></span></div><div style="position:absolute; border: textbox 1px solid; writing-mode:lr-tb; left:72px; top:24038px; width:31px; height:8px;"><span style="font-family: ArialMT; font-size:8px">Page 27
<br></span></div>

<div style="position:absolute; top:24131px;"></div>
<div style="position:absolute; border: textbox 1px solid; writing-mode:lr-tb; left:72px; top:24202px; width:331px; height:19px;"><span style="font-family: ArialMT; font-size:9px">

'''

soup = BeautifulSoup(txt, 'html.parser')
raw_text = soup.get_text(strip=True, separator='\n')
t = re.search(r'19\s+domestic and stock rights(.*?)20\s+native title rights', raw_text, flags=re.S|re.I).group(1)
print(t)
