如何用正则表达式匹配PDF中的编号语句？

我有一份PDF文件，使用PyPDF2提取文本后，需要编写正则表达式捕获其中的编号语句。尝试了两种正则均未达到预期：要么无法捕获完整句子，要么将换行符视为语句分隔符导致内容被拆分为多行。期望将每个编号点捕获为完整的单个句子，示例输出如下：

[
    '1. Please admit that Plaintiff, JOSHUA PINK, received benefits from a collateral source, as defined by §768.76, Florida Statutes, for medical bills alleged to have been incurred as a result of the incident described in the Complaint.',
    '2. Please admit that Plaintiff, JOSHUA PINK, received benefits from a collateral source, as defined by §768.76, Florida Statutes, for loss of wages or income alleged to have been sustained as a result of the incident described in the Complaint.',

现有正则的错误输出 #

• regex2输出（语句被拆分为多行）：

[('2022', 'CA-002235 '),
 ('1', 'Florida Rul es of Civil Procedure, requests the Plaintiff,'),
 ('1',
  'Please admit that Plaintiff, JOSHUA PINK , received benefits from a collateral'),
 ('768',
  'Florida Statute s, for medical bills alleged to have been incurred as'),...]

• regex1输出（未捕获完整语句）：

原有代码 #

def read_pdf(name):
    reader = PdfReader(name,"rb")
    text = ""
    for page in reader.pages:
        text += page.extract_text() + "\n"

    #regex1 = r'(^[0-9].*)'
    regex2 = r'([\d]+).+?([a-zA-Z].+).'
    pat = re.compile(regex, re.M)

    extracted_text = pat.findall(text)

    return text,extracted_text

text,pdf1 = read_pdf(names[0])

修正后的解决方案 #

关键改进点 #

1. 文本预处理：修复PDF提取时的断词（如Rul es→Rules），合并换行内容，去除页码干扰（如2 4.→4.）
2. 正则优化：使用正向预查匹配完整语句范围，同时启用re.DOTALL让.匹配换行符

修正代码 #

import re
from PyPDF2 import PdfReader

def read_pdf(name):
    reader = PdfReader(name)
    text = ""
    for page in reader.pages:
        text += page.extract_text() + "\n"
    
    # 预处理：合并换行与空格，修复断词，移除页码干扰
    processed_text = re.sub(r'\n\s+', ' ', text)
    processed_text = re.sub(r'(\w+)\s+(\w+)', r'\1\2', processed_text)
    processed_text = re.sub(r'\d+\s+(\d+\.)', r'\1', processed_text)
    
    # 正则匹配：捕获从数字.开始，到下一个数字.或文档结尾的完整语句
    regex = r'(\d+\. .*?)(?=\s*\d+\.|$)'
    pat = re.compile(regex, re.DOTALL)
    
    # 去除结果中的多余空格
    extracted_text = [item.strip() for item in pat.findall(processed_text)]
    
    return text, extracted_text

# 调用示例
text, pdf1 = read_pdf("your_pdf_file.pdf")
for item in pdf1:
    print(item)

正则说明 #

• \d+\. .*?：匹配以数字加句号开头的内容，非贪婪模式避免过度匹配
• (?=\s*\d+\.|$)：正向预查，匹配到下一个数字句号或文档结尾，确保捕获完整语句
• re.DOTALL：让.匹配包括换行在内的所有字符，处理跨多行的语句
