图书解析

主要解析一下格式的图书:

  • PDF(非扫描版)
  • EPUB
  • MOBI

Requirements

具体见requirement.txt

PDF格式解析

DocAI:复旦大学自然语言处理实验室自2019年起,自主开发的非扫描件PDF处理工具。

注册并登录即可使用。

亦可使用python第三方库PyPDF2解析:

import PyPDF2
import os
# 保存每页文本信息
page_info = []
try:
    # 指定pdf文件路径
    book_path = os.path.join(pdf_chinese_md5_dir,PDF_MD5)
    with open(book_path, 'rb') as pdf_fp:
        pdf_reader = PyPDF2.PdfReader(pdf_fp)
    if pdf_reader.is_encrypted:
        # 如果PDF文档是加密的,则需要提供密码才能继续处理
        pass
    else:
        # 遍历每一页并提取文本信息
        for i in range(len(pdf_reader.pages)):
            page = pdf_reader.pages[i]
            text = page.extract_text()
            # 如果提取到的文本信息非空,则认为该PDF文档包含文本信息
            if text.strip():
                page_info.append(text.strip()+'\n')
except Exception as e:
	print(e)

EPUB格式解析

import zipfile
from bs4 import BeautifulSoup
import os
# 每个chapter文本
chapter_content_list = []
# 指定epub文件路径
book_path = os.path.join(epub_chinese_md5_dir,EPUB_MD5)
# 使用ZipFile库打开epub文件
book = zipfile.ZipFile(book_path)
# 获取书籍的文本HTML名称
xhtml_data = [string for string in book.namelist() if string.endswith('xhtml') or string.endswith('html') or string.endswith('xml')]
# 解析每个HTML文本格式
for k in range(len(xhtml_data)):
    try:
        chapter_file = book.open(unquote(xhtml_data[k]))
        chapter_content = chapter_file.read().decode('utf-8')
        chapter_content = BeautifulSoup(chapter_content, 'html')
        chapter_content_list.append(chapter_content.get_text().strip())
    except Exception as e:
        print(e)
    continue

MOBI格式解析

import mobi
import shutil
from bs4 import BeautifulSoup
import os
# 指定mobi文件路径
book_path = os.path.join(mobi_chinese_md5_dir,MOBI_MD5)
# 提取TMP文件路径
tempdir, filepath = mobi.extract(book_path)
#获取HTML文件内容后删除中间文件
try:
    with open(filepath,'r',encoding='utf-8') as mobi_fp:
        chapter_content = mobi_fp.read()
    shutil.rmtree(tempdir)
    #利用BeautifulSoup提取HTML文本信息并作格式化后重新提取
    chapter_content = BeautifulSoup(chapter_content, 'html.parser')
    chapter_content = chapter_content.prettify()
    chapter_content = BeautifulSoup(chapter_content, 'html.parser')
    file_content = chapter_content.get_text().strip()
except Exception as e:
    print(e)
