The code above is written against an old version of the API, see my comment below. Pdfminer is an invaluable tool for pdf-scraping.įrom pdflib.page import TextItem, TextConverterįrom pdflib.pdfparser import PDFDocument, PDFParserįrom pdflib.pdfinterp import PDFResourceManager, PDFPageInterpreterĭevice = CsvConverter(rsrc, outfp, "ascii") Other tools I tried include pdftotext, ps2ascii and the online tool. Using this approach, I was able to extract text from a pdf that no other tool was able to extract content suitable for further parsing from. The function simply sorts the TextItem content objects according to their y and x coordinates, and outputs items with the same y coordinate as one text line, separating the objects on the same line with ' ' characters. I did this to convert pdf contents to semi-colon separated text, using the code below. You have access to the pdf's content model, and can create your own text extraction. You can also quite easily use pdfminer as a library. See below code that works for Python 3: import sys # Process each page contained in the document. Interpreter = PDFPageInterpreter(rsrcmgr, device) This will work for those who are getting import errors with process_pdf import sysįrom nverter import XMLConverter, HTMLConverter, TextConverterĭevice = TextConverter(rsrcmgr, retstr, codec=codec, laparams=laparams) Since none for these solutions support the latest version of PDFMiner I wrote a simple solution that will return text of a pdf using PDFMiner. Line = child._text.encode(dec) #<- changedĭevice = CsvConverter(rsrc, outfp, codec="utf-8", laparams=LAParams()) Updated for version 20110515 (thanks to Oeufcoque Penteano!): def pdf_to_csv(filename):įrom nverter import LTChar, TextConverterįor child in self.cur_item._objs: #<- changed If isinstance(child, LTChar): #<- changedĭevice = CsvConverter(rsrc, outfp, codec="utf-8", laparams=LAParams()) #<- changed def pdf_to_csv(filename):įrom nverter import LTChar, TextConverter #<- changed In short I replaced LTTextItem with LTChar and passed an instance of LAParams to the CsvConverter constructor. Here is an update for the latest version in pypi, 20100619p1.

Several schema systems exist to aid in the definition of XML-based languages, while programmers have developed many application programming interfaces (APIs) to aid the processing of XML data.Īdobe Acrobat, Adobe InDesign, Adobe FrameMaker, Adobe Illustrator, Adobe Photoshop, Google Docs, LibreOffice, Microsoft Office, Foxit Reader, Ghostscript. XML is a textual data format with strong support via Unicode for different human languages. A structured storage system to bundle these elements and any associated content into a single file, with data compression where appropriate. A font-embedding/replacement system to allow fonts to travel with the documents. The PDF combines three technologies: A subset of the PostScript page description programming language, for generating the layout and graphics. The design goals of XML emphasize simplicity, generality, and usability across the Internet. In computing, Extensible Markup Language (XML) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. Each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, graphics, and other information needed to display it. The Portable Document Format (PDF) is a file format used to present documents in a manner independent of application software, hardware, and operating systems.
