如何使用漂亮的汤列出 html 文件中所有具有 PA/ 的字符串

Question

我有一个将 pdf 转换成 html 的程序，我需要补充这个程序，所以在转换后它会搜索标签 PA/ 和它前面的字符，并将这些标签和字符保存到CSV 文件，我正在尝试这样做，但我做不到。

目前的代码如下：

import shlex
import subprocess
import os
import platform
from bs4 import BeautifulSoup
import re
import csv
import pickle
def rename_files():
    file_list = os.listdir(r"C:\PROJECT\pdfs")
    print(file_list)
    saved_path = os.getcwd()
    print('Current working directory is '+saved_path)
    os.chdir(r'C:\PROJECT\pdfs')
    for file_name in file_list:
        os.rename(file_name, file_name.translate(None, " "))
    os.chdir(saved_path)
rename_files()

def run(command):
    if platform.system() != 'Windows':
        args = shlex.split(command)
    else:
        args = command
    s = subprocess.Popen(args,
                         stdout=subprocess.PIPE,
                         stderr=subprocess.PIPE)
    output, errors = s.communicate()
    return s.returncode == 0, output, errors

# Change this to your PDF file base directory
base_directory = 'C:\PROJECT\pdfs'
if not os.path.isdir(base_directory):
    print "%s is not a directory" % base_directory
    exit(1)
# Change this to your pdf2htmlEX executable location
bin_path = 'C:\Python27\pdfminer-20140328\tools\pdf2txt.py'
if not os.path.isfile(bin_path):
    print "Could not find %s" % bin_path
    exit(1)
for dir_path, dir_name_list, file_name_list in os.walk(base_directory):
    for file_name in file_name_list:
        # If this is not a PDF file
        if not file_name.endswith('.pdf'):
            # Skip it
            continue
        file_path = os.path.join(dir_path, file_name)
        # Convert your PDF to HTML here
        args = (bin_path, file_name, file_path)
        success, output, errors = run("python %s -o %s.html %s " %args)
        if not success:
            print "Could not convert %s to HTML" % file_path
            print "%s" % errors
htmls_path = 'C:\PROJECT'
for dir_path, dir_name_list, file_name_list in os.walk(htmls_path):
    for file_name in file_name_list:
        if not file_name.endswith('.html'):
            continue
        with open(file_name) as markup:
            soup = BeautifulSoup(markup.read())
            text = soup.get_text()
            match = re.findall("PA/(\S*)\s*(\S*)", text)
            print(match)
with open ('score.csv', 'w') as f:
    writer = csv.writer(f)
    writer.writerows('%s' %match)

html 太大了，我会在这里写一部分，包括 PA 和我不想要的文本：

<html>
    <title>Testing</title>
    <body>
        <div style="position:absolute; border: textbox 1px solid; writing-mode:lr-tb; left:59px; top:34023px; width:84px; height:32px;"><span style="font-family: YFEHEP+Times-Bold; font-size:17px">JUST SOME TEXT THAT I DON'T WANT TO HAVE ON THE CSV FILE
        <br></span><span style="font-family: YFEHEP+Times-Roman; font-size:16px">PA/00986/17 GTD
        <br></span></div><div style="position:absolute; border: textbox 1px solid; writing-mode:lr-tb; left:59px; top:34066px; width:84px; height:16px;"><span style="font-family: YFEHEP+Times-Roman; font-size:16px">PA/01008/17 GTD
        <br></span></div><div style="position:absolute; border: textbox 1px solid; writing-mode:lr-tb; left:59px; top:34105px; width:84px; height:16px;"><span style="font-family: YFEHEP+Times-Roman; font-size:16px">PA/01095/17 GTD
    </body>
</html>

    import re

            <div style="position:absolute; border: textbox 1px solid; writing-mode:lr-tb; left:59px; top:34023px; width:84px; height:32px;"><span style="font-family: YFEHEP+Times-Bold; font-size:17px">JUST SOME TEXT THAT I DON'T WANT TO HAVE ON THE CSV FILE

            <br></span></div><div style="position:absolute; border: textbox 1px solid; writing-mode:lr-tb; left:59px; top:34066px; width:84px; height:16px;"><span style="font-family: YFEHEP+Times-Roman; font-size:16px">PA/01008/17 GTD

        </body>
    </html>
    """

    soup = BeautifulSoup(html_doc, 'html.parser')
    text = soup.get_text()

    match = re.findall("PA/(\S*)\s*(\S*)", text)
    print(match)

用于写入 CSV

import csv
with open('ur file.csv','wb') as out:
    csv_out=csv.writer(out)
    csv_out.writerow(['fist_col','second_col'])
    for row in match:
        csv_out.writerow(row)
