python3docx在两段之间获取文本

Question

我在一个目录中有.docx文件，我想得到两段之间的所有文本

示例：

Foo :

The foo is not easy, but we have to do it. We are looking for new things in our ad libitum way of life.

Bar :

我想得到：

The foo is not easy, but we have to do it.
We are looking for new things in our ad libitum way of life. 

我写了这段代码：

import docx
import pathlib
import glob
import re

def rf(f1):
    reader = docx.Document(f1)
    alltext = []
    for p in reader.paragraphs:
        alltext.append(p.text)
    return '\n'.join(alltext)


for f in docxfiles:
    try:
        fulltext = rf(f)
        testf = re.findall(r'Foo\s*:(.*)\s*Bar', fulltext, re.DOTALL)
        
        print(testf)
    except IOError:
        print('Error opening',f)

它返回None

我做错了什么

Answer 1

如果循环所有段落并打印段落文本，则文档文本将保持原样，但循环的单个p.text不包含完整的文档文本

它与字符串一起工作：

t = """Foo :

The foo is not easy, but we have to do it. We are looking for new things in our ad libitum way of life.

Bar :"""
      
import re
      
fread = re.search(r'Foo\s*:(.*)\s*Bar', t)
      
print(fread)  # None  - because dots do not match \n
     
fread = re.search(r'Foo\s*:(.*)\s*Bar', t, re.DOTALL)
      
print(fread)
print(fread[1])

输出：

<_sre.SRE_Match object; span=(0, 115), match='Foo :\n\nThe foo is not easy, but we have to do i>


The foo is not easy, but we have to do it. We are looking for new things in our ad libitum way of life.

如果你使用

for p in reader.paragraphs:
    print("********")
    print(p.text)
    print("********")

你知道为什么你的正则表达式不匹配了。您的正则表达式可以处理整个文档文本

您还可以查找与r'Foo\s*:'匹配的段落，然后将下面所有段落.文本放入列表，直到找到与r'\s*Bar'匹配的段落
