Pythons Library Pdfreader For Pdf Extraction Wont Iterate Trough Pages

I want to extract text from PDF file with Python's lib called pdfreader. I followed the instructions here: https://pdfreader.readthedocs.io/en/latest/tutorial.html#how-to-browse-do

Solution 1:

Solving this issue required a lot of documentation reading for the Python module pdfreader. I was shocked at the level of difficulty in using this module for simple text extraction. It took hours to figure out a working solution.

The code below will enumerate the text on individual pages. You will still need to do some text cleaning to get your desired output.

I noted that one of your PDFs is having a problem with some font encoding during the parsing, which throws a warning message.

import requests
from io import BytesIO
from pdfreader import SimplePDFViewer

pdf_links = [
    'https://www.buelach.ch/fileadmin/files/documents/Finanzen/Finanz-_und_Aufgabenplan_2020-2024_2020-09-14.pdf',
    'https://www.buelach.ch/fileadmin/files/documents/Finanzen/201214_budget2021_aenderungen_gr.pdf',
    'http://www.dielsdorf.ch/dl.php/de/5e8c284c3b694/2020.04.06.pdf',
    'http://www.dielsdorf.ch/dl.php/de/5f17e472ca9f1/2020.07.20.pdf']

for pdf_link in pdf_links:

    response = requests.get(pdf_link, stream=True)

    # extract text page by pagewith BytesIO(response.content) as data:

        viewer = SimplePDFViewer(data)

        all_pages = [p for p in viewer.doc.pages()]
        number_of_pages = len(all_pages)
        for page_number inrange(1, number_of_pages + 1):
            viewer.navigate(int(page_number))
            viewer.render()
            page_strings = " ".join(viewer.canvas.strings).replace('     ', '\n\n').strip()
            print(f'Current Page Number: {page_number}')
            print(f'Page Text: {page_strings}')
