我需要从多个填写的pdfs中提取数据。

Question

我需要从多个填好的pdfs中提取数据，有人能修改我的答案吗？

from fillpdf import fillpdfs

import os

import glob

import pdfplumber

import PyPDF2

for file in glob.glob("C:/Users/Sam/OneDrive/Desktop/Pro/*.pdf"):
    with pdfplumber.open(file) as pdf:
        page = pdf.pages[0]
        text = page.extract_text()
        text = " ".join(text.split())
        print(text)

使用PDFplumber，请参阅GitHub：提取表格值上的文档。

import glob
import pdfplumber

def extract_text(pdf):
    page = pdf.pages[0]
    text = page.extract_text()
    text = " ".join(text.split())
    return text


def extract_form(pdf):
    if "AcroForm" not in pdf.doc.catalog.keys():
        return None
    form = pdf.doc.catalog["AcroForm"]
    form_data = {}
    for field in form["Fields"]:
        f = field.resolve()
        field_name = f["T"]
        field_value = f["V"] if 'V' in f.keys() else None
        form_data[field_name] = field_value
    return form_data


for file in glob.glob("output*.pdf"):
    print(f"- File: {file}")
    with pdfplumber.open(file) as pdf:
        text = extract_text(pdf)
        print(f"--- Text:\n{text}")
        form = extract_form(pdf)
        print(f"--- Form Data:\n{form}")

指纹：

- File: output_filled.pdf
--- Text:
First Name: Last Name: Street Address: Apt #: Zipcode: City: Spirit: Date: Evil: Language: Français Esperanto Latin Signature:
--- Form Data:
{b'Given Name Text Box': b'Hello', b'Family Name Text Box': b'World', b'Address 1 Text Box': b'\xfe\xff', b'City Text Box': b'\xfe\xff', b'Gender List Box': b'Panda', b'Height Formatted Field': None, b'Driving License Check Box': /'Off', b'Apt Number Text Box': b'\xfe\xff', b'Zipcode Text Box': b'\xfe\xff', b'Latin Check Box': /'Off', b'French Check Box': None, b'Esperanto Check Box': None, b'signature_1': None}

用PDFjinja的例子的文件进行测试

1. 手动填写sample.pdf (有表单数据值)
2. 原始output.pdf (只有文本)
