PDFMiner allows one to obtain the exact location of text in a page, as well as other information such as fonts or lines. Unlike other PDF-related tools, it focuses entirely on getting and analyzing text data. PDFMiner is a tool for extracting information from PDF documents. In any case, pyPDF is not format-aware, so the output looks like PDFMiner This solves the UnicodeEncodeError during the processing of “naaclo6-shinyama.pdf”. PYTHON CONVERT PDF TO TEXT CODEThe output from this code didn’t make much difference compared to the previous code snippet, except call an encode method at the end. Print getPDFContent(filename).encode("ascii", "xmlcharrefreplace") # print getPDFContent(filename).encode("ascii", "ignore") # Extract text from page and add to contentĬontent = pdf.getPage(i).extractText() "/n"Ĭontent = " ".join(content.replace(u"/xa0", " ").strip().split()) Pdf = pyPdf.PdfFileReader(file(path, "rb")) Parent = "C:/Users/victoryee/Google Drive/Projects/extract-pdf-text"įilename = os.path.abspath('naacl06-shinyama.pdf') With “naacl06-shinyama.pdf” (a typical research publication article), pyPDF returns the error: “ UnicodeEncodeError: 'ascii' codec can't encode character u'\ufb01' in position 1933: ordinal not in range(128)”ĪctiveState recipe #511465 defines a wrapper function for this for loop: # Reference With “dmca.pdf” (a secured read-only PDF), pyPDF returns the error: “ Exception: file has not been decrypted“. I tried a few more PDFMiner samples with this snippet. With simple1.pdf, simple2.pdf, and simple3.pdf, this code snippet returns an error: ” ValueError: invalid literal for int() with base 10: '>' ” while trying to find the start of the PDF’s xref table. The PDF in this example is located at “D:\Projects\extract-pdf-text\samples\simple1.pdf,” which essentially reads as “Hello World.” This sample PDF is included with PDFMiner’s source, along with “simple2.pdf” (embedded images) and “simple3.pdf” (no visible objects in PDF). Input = PdfFileReader(file(filename, "rb")) Parent = "D:/Projects/samples/extract-pdf-text"įilename = os.path.abspath('simple1.pdf') The most basic way to extract text using pyPDF’s extractText() is: import os There are no code examples or samples for extractText() in the pyPDF documentation May be overhauled to provide more ordered text in the future. Stability: Added in v1.7, will exist for all future v1.x releases. Do not rely on the order of text coming out of this function, as it will change if this function is made more sophisticated. PYTHON CONVERT PDF TO TEXT GENERATORThis works well for some PDF files, but poorly for others, depending on the generator used. Locate all text drawing commands, in the order they are provided in the content stream, and extract the text. pyPDFĪccording to its documentation, pyPDF includes a text extraction method called extractText() in its PageObject class: Out of curiosity, I wanted to try both of them out for text extraction. From a glance at their respective documentations, pyPDF looked more suited toward PDF manipulation, and PDFMiner, toward text extraction. I have not used PDFMiner before, but saw it referenced many times when searching for PDF-to-text conversion Python libaries. PYTHON CONVERT PDF TO TEXT FULLI’ve previously mentioned pyPDF in a post on counting the number of pages of each PDF in a directory full of PDFs. This quick post describes my initial experience with pyPDF and PDFMiner.
