使用python解决中英混合参考文献中et al 和等的问题

这个代码使用zipfile将docx进行解压，然后操作document.xml文件，找到中文中的et al之后替换为“等”，然后再压缩为docx

import zipfile
import re
import os
import shutil
from lxml import etree

def replace_etal(filepath):
    temp_dir = 'temp_dir'
    temp_filename = os.path.join(temp_dir, 'word/document.xml')

    # Create a temporary directory and extract the docx file into it
    with zipfile.ZipFile(filepath, 'r') as docx:
        docx.extractall(temp_dir)

    # Parse the XML document
    with open(temp_filename, 'r', encoding='utf-8') as f:
        tree = etree.parse(f)

    root = tree.getroot()

    # Get the default namespace
    default_ns = re.match(r'\{.*\}', root.tag).group(0)[1:-1]  # We remove the {} 

    # Create a variable to store the text of the previous 't' element
    prev_text = ''

    # Iterate over every 't' element in the XML
    for element in root.findall('.//{{{}}}t'.format(default_ns)):
        print(element.text)
        # If the element text contains 'et al.' and the previous text contains Chinese characters, replace 'et al.' with '等'
        if element.text and 'et al.' in element.text and re.search(r'[\u4e00-\u9fa5]', prev_text):
            element.text = element.text.replace('et al.', '等.')

        # Update the previous text
        if element.text:
            prev_text = element.text
        else:
            prev_text = ''

    # Write the modified XML back to the temporary file
    with open(temp_filename, 'wb') as f:
        f.write(etree.tostring(root))

    # Create a new zip file with all contents of the temporary directory
    with zipfile.ZipFile( filepath, 'w') as docx:
        for folderName, subfolders, filenames in os.walk(temp_dir):
            for filename in filenames:
                # create complete filepath of file in directory
                filePath = os.path.join(folderName, filename)
                # Add file to zip
                docx.write(filePath, arcname=filePath.replace(temp_dir, ''))

    # Delete the temporary directory
    shutil.rmtree(temp_dir)

    return  filepath # 返回修改后的文件名

def openword(odocx):
    # 打开文档
    app_path = "\"C:\\Program Files\\Microsoft Office\\root\\Office16\\WINWORD.EXE\"" # Word应用程序路径，根据实际安装路径修改
    os.system(f'{app_path} {odocx}')

odocx = replace_etal('测试文档.docx')
openword(odocx)
