I have placed a pdf in my C:\ drive. it is called "Components-of-Dot-
NET.pdf" You could use anything I was just testing with it.

I was using the last script on that page that was most recently
updated. I am using python 2.6.

http://code.activestate.com/recipes/511465-pure-python-pdf-to-text-co...

import pyPdf

def getPDFContent(path):
? ? content = "C:\Components-of-Dot-NET.pdf"
? ? # Load PDF into pyPDF
? ? pdf = pyPdf.PdfFileReader(file(path, "rb"))
? ? # Iterate pages
? ? for i in range(0, pdf.getNumPages()):
? ? ? ? # Extract text from page and add to content
? ? ? ? content += pdf.getPage(i).extractText() + "\n"
? ? # Collapse whitespace
? ? content = " ".join(content.replace(u"\xa0", " ").strip().split())
? ? return content

print getPDFContent("Components-of-Dot-NET.pdf").encode("ascii",
"ignore")

This is my error.

Looks like a issue with finding the file.
how do you pass the path?

okay thanks I thought that when I set content here

def getPDFContent(path):
? ? content = "C:\Components-of-Dot-NET.pdf"

that i was defining where it is.

but yeah I updated script to below and it works. That is the contents
are displayed to the interpreter. How do I output to a .txt file?

import pyPdf

def getPDFContent(path):
? ? content = "C:\Components-of-Dot-NET.pdf"
? ? # Load PDF into pyPDF
? ? pdf = pyPdf.PdfFileReader(file(path, "rb"))
? ? # Iterate pages

? ? ? ? # Extract text from page and add to content
? ? ? ? content += pdf.getPage(i).extractText() + "\n"
? ? # Collapse whitespace
? ? content = " ".join(content.replace(u"\xa0", " ").strip().split())
? ? return content

print getPDFContent(r"C:\Components-of-Dot-NET.pdf").encode("ascii",
"ignore")

I have found far more advanced scripts searching around. But will have
to keep trying as I cannot get an output file or specify the path.

Edit very strangely whilst searching for examples I found my own post
just written here ranking number 5 on google within 2 hours. Bizzare.

Replicates our thread as thiers. I was searching ggole with "pypdf

There's no global variable content, that was local to the function. ?So
it's lost when the function exits. ?it does return the value, but you
give it to print, and don't save it anywhere.

data = getPDFContent(r"C:\Components-of-Dot-NET.pdf").encode("ascii",
"ignore")

outfile = open('x.txt', 'w')
outfile.write(data)

close(outfile)

I used a different name to emphasize that this is *not* the same
variable as content inside the function. ?In this case, it happens to
have the same value. ?And if you used the same name, you could be
confused about which is which.

That simply binds to a local name; 'content' is a local variable in the
function 'getPDFContent'.
'content' now contains the text of the PDF, starting with
r"C:\Components-of-Dot-NET.pdf".
Outputting to a .txt file is simple: open the file for writing using
'open', write the string to it, and then close it.
