[FIXED] How to filter text from text from image with python?

Issue

I can extract text from an image in pdf. The text that is extracted from the image is like this:

Koopliedenweg 38\nDeb. nr. : 108636 2991 LN BARENDRECHT\nYour VAT nr. : NL851703884B01 Nederland\nFactuur datum : 19-11-21\nAantal Omschrijving Prijs Bedrag\nOrder number : 76372 Loading date : 15-11-21 Incoterm: : FOT\nYour ref. : SCHOOLFRUIT Delivery date :\nWK46\nVerdi Import Schoolfruit\n566 Ananas 
Crownless 14kg 10 Sweet CR Klasse I € 7,00 € 3.962,00\n706 Appels Royal Gala 13kg 60/65 Generica PL Klasse I € 4,68 € 3.304,08\n598 Peen Waspeen 14x1lkg 200-400 Generica BE Klasse I € 6,30 3.767,40\nOrder number : 76462 Loading date : 18-11-21 Incoterm: : FOT\nYour ref. : SCHOOLFRUIT Delivery date

But now I want to return some specific text. So in this case I am looking for the string: Appels Royal Gala 13kg So I try it like this:

import io
from PIL import Image
import pytesseract
from wand.image import Image as wi

pdfFile = wi(filename = "C:\\Users\\engel\\Documents\\python\\docs\\fixedPDF.pdf", resolution = 300)
image = pdfFile.convert('jpeg')

imageBlobs = []


for img in image.sequence:
    imgPage = wi(image = img)
    imageBlobs.append(imgPage.make_blob('jpeg'))

extract = []

for imgBlob in imageBlobs:
    image = Image.open(io.BytesIO(imgBlob))
    text = pytesseract.image_to_string(image, lang = 'eng')
    extract.append(text)
    interested_string = 'Appels Royal Gala 13kg'
    line = [l[1] for l in extract if 'Appels Royal Gala 13kg' in l[1]]
print(line)

But the result is an empty array: []

So what I have to change?

Thank you

oke, if I do this:

    line = [l[1] for l in extract if 'Appels Royal Gala 13kg' in l] 

I get this as output:

['=']

and then if I do it like this:

for imgBlob in imageBlobs:
    image = Image.open(io.BytesIO(imgBlob))
    text = pytesseract.image_to_string(image, lang='eng')
    extract.append(text)
    interested_string = 'Verdi Import Schoolfruit'   
line = [l[1] for l in extract if 'It was the best of' in l]

print(line)

then the result is:

['t']

oke, If I do this:

line = [l for l in extract if 'It was the best of' in l]

print(extract)

print(line)

then I get this as output:

['It was the best of\ntimes, it was the worst\nof times, it was the age\nof wisdom, it was the\nage of foolishness...\n\x0c']
['It was the best of\ntimes, it was the worst\nof times, it was the age\nof wisdom, it was the\nage of foolishness...\n\x0c']

Solution

You are doing

line = [l[1] for l in extract if 'Appels Royal Gala 13kg' in l[1]]

You are looking for your string in l[1] but l[1] is only the second letter of your sentence, so maybe:

line = [l[1] for l in extract if 'Appels Royal Gala 13kg' in l]
