I am trying to allow user to upload MS Word file and then I run a certain function that takes a string as input argument. I am uploading Word file through FileUpload however I am getting a coded object. I am unable to decode using byte UTF-8 and using upload.value or upload.data just returns coded text
Any ideas how I can extract content from uploaded Word File?
> upload = widgets.FileUpload()
> upload
#I select the file I want to upload
> upload.value #Returns coded text
> upload.data #Returns coded text
> #Previously upload['content'] worked, but I read this no longer works in IPYWidgets 8.0
Modern ms-word files (.docx) are actually zip-files.
The text (but not the page headers) are actually inside an XML document called word/document.xml in the zip-file.
The python-docx module can be used to extract text from these documents. It is mainly used for creating documents, but it can read existing ones. Example from here.
>>> import docx
>>> gkzDoc = docx.Document('grokonez.docx')
>>> fullText = []
>>> for paragraph in doc.paragraphs:
... fullText.append(paragraph.text)
...
Note that this will only extract the text from paragraphs. Not e.g. the text from tables.
Edit:
I want to be able to upload the MS file through the FileUpload widget.
There are a couple of ways you can do that.
First, isolate the actual file data. upload.data is actually a dictionary, see here. So do something like:
rawdata = upload.data[0]
(Note that this format has changed over different version of ipywidgets. The above example is from the documentation of the latest version. Read the relevant version of the documentation, or investigate the data in IPython, and adjust accordingly.)
write rawdata to e.g. foo.docx and open that. That would certainly work, but it does seem somewhat un-elegant.
docx.Document can work with file-like objects. So you could create an io.BytesIO object, and use that.
Like this:
foo = io.BytesIO(rawdata)
doc = docx.Document(foo)
Tweaking with #Roland Smith great suggestions, following code finally worked:
import io
import docx
from docx import Document
upload = widgets.FileUpload()
upload
rawdata = upload.data[0]
test = io.BytesIO(rawdata)
doc = Document(test)
for p in doc.paragraphs:
print (p.text)
As I am new to the python programming, I want to open a .docx file, parse it, find occurrence of particular string in multiple places and then adding two lines after that in whole document. How can i do these thing using python script?
You could do this as follows using win32com:
import win32com.client
search_for = "This is some text in my file"
add_lines = "^pLine1^pLine2^pLine3" # ^p creates a new line
word = win32com.client.Dispatch("Word.Application")
word.Visible = False
word.DisplayAlerts = False
doc = word.Documents.Open(r'c:\my_folder\my_file.docx')
const = win32com.client.constants
find = doc.Content.Find
find.ClearFormatting()
find.Replacement.ClearFormatting()
find.Execute(Forward=True, Replace=const.wdReplaceAll, FindText=search_for, ReplaceWith=search_for+add_lines)
word.ActiveDocument.SaveAs(r'c:\my_folder\my_file_output.docx')
word.Quit()
To change the colour of the replacement text you could also add the following before the find.Execute:
find.Replacement.Font.Color = 255 # wdColorRed
A full list of standard Word colours is listed on the Microsoft site.
for working with MS word files in python, there is python win32 extensions, which can be used in windows. How do I do the same in linux?
Is there any library?
Use the native Python docx module. Here's how to extract all the text from a doc:
document = docx.Document(filename)
docText = '\n\n'.join(
paragraph.text for paragraph in document.paragraphs
)
print(docText)
See Python DocX site
Also check out Textract which pulls out tables etc.
Parsing XML with regexs invokes cthulu. Don't do it!
You could make a subprocess call to antiword. Antiword is a linux commandline utility for dumping text out of a word doc. Works pretty well for simple documents (obviously it loses formatting). It's available through apt, and probably as RPM, or you could compile it yourself.
benjamin's answer is a pretty good one. I have just consolidated...
import zipfile, re
docx = zipfile.ZipFile('/path/to/file/mydocument.docx')
content = docx.read('word/document.xml').decode('utf-8')
cleaned = re.sub('<(.|\n)*?>','',content)
print(cleaned)
OpenOffice.org can be scripted with Python: see here.
Since OOo can load most MS Word files flawlessly, I'd say that's your best bet.
I know this is an old question, but I was recently trying to find a way to extract text from MS word files, and the best solution by far I found was with wvLib:
http://wvware.sourceforge.net/
After installing the library, using it in Python is pretty easy:
import commands
exe = 'wvText ' + word_file + ' ' + output_txt_file
out = commands.getoutput(exe)
exe = 'cat ' + output_txt_file
out = commands.getoutput(exe)
And that's it. Pretty much, what we're doing is using the commands.getouput function to run a couple of shell scripts, namely wvText (which extracts text from a Word document, and cat to read the file output). After that, the entire text from the Word document will be in the out variable, ready to use.
Hopefully this will help anyone having similar issues in the future.
Take a look at how the doc format works and create word document using PHP in linux. The former is especially useful. Abiword is my recommended tool. There are limitations though:
However, if the document has complicated tables, text boxes, embedded spreadsheets, and so forth, then it might not work as expected. Developing good MS Word filters is a very difficult process, so please bear with us as we work on getting Word documents to open correctly. If you have a Word document which fails to load, please open a Bug and include the document so we can improve the importer.
(Note: I posted this on this question as well, but it seems relevant here, so please excuse the repost.)
Now, this is pretty ugly and pretty hacky, but it seems to work for me for basic text extraction. Obviously to use this in a Qt program you'd have to spawn a process for it etc, but the command line I've hacked together is:
unzip -p file.docx | grep '<w:t' | sed 's/<[^<]*>//g' | grep -v '^[[:space:]]*$'
So that's:
unzip -p file.docx: -p == "unzip to stdout"
grep '<w:t': Grab just the lines containing '<w:t' (<w:t> is the Word 2007 XML element for "text", as far as I can tell)
sed 's/<[^<]>//g'*: Remove everything inside tags
grep -v '^[[:space:]]$'*: Remove blank lines
There is likely a more efficient way to do this, but it seems to work for me on the few docs I've tested it with.
As far as I'm aware, unzip, grep and sed all have ports for Windows and any of the Unixes, so it should be reasonably cross-platform. Despit being a bit of an ugly hack ;)
If your intention is to use purely python modules without calling a subprocess, you can use the zipfile python modude.
content = ""
# Load DocX into zipfile
docx = zipfile.ZipFile('/home/whateverdocument.docx')
# Unpack zipfile
unpacked = docx.infolist()
# Find the /word/document.xml file in the package and assign it to variable
for item in unpacked:
if item.orig_filename == 'word/document.xml':
content = docx.read(item.orig_filename)
else:
pass
Your content string however needs to be cleaned up, one way of doing this is:
# Clean the content string from xml tags for better search
fullyclean = []
halfclean = content.split('<')
for item in halfclean:
if '>' in item:
bad_good = item.split('>')
if bad_good[-1] != '':
fullyclean.append(bad_good[-1])
else:
pass
else:
pass
# Assemble a new string with all pure content
content = " ".join(fullyclean)
But there is surely a more elegant way to clean up the string, probably using the re module.
Hope this helps.
Unoconv might also be a good alternative: http://linux.die.net/man/1/unoconv
To read Word 2007 and later files, including .docx files, you can use the python-docx package:
from docx import Document
document = Document('existing-document-file.docx')
document.save('new-file-name.docx')
To read .doc files from Word 2003 and earlier, make a subprocess call to antiword. You need to install antiword first:
sudo apt-get install antiword
Then just call it from your python script:
import os
input_word_file = "input_file.doc"
output_text_file = "output_file.txt"
os.system('antiword %s > %s' % (input_word_file, output_text_file))
If you have LibreOffice installed, you can simply call it from the command line to convert the file to text, then load the text into Python.
Is this an old question?
I believe that such thing does not exist.
There are only answered and unanswered ones.
This one is pretty unanswered, or half answered if you wish.
Well, methods for reading *.docx (MS Word 2007 and later) documents without using COM interop are all covered.
But methods for extracting text from *.doc (MS Word 97-2000), using Python only, lacks.
Is this complicated?
To do: not really, to understand: well, that's another thing.
When I didn't find any finished code, I read some format specifications and dug out some proposed algorithms in other languages.
MS Word (*.doc) file is an OLE2 compound file.
Not to bother you with a lot of unnecessary details, think of it as a file-system stored in a file. It actually uses FAT structure, so the definition holds. (Hm, maybe you can loop-mount it in Linux???)
In this way, you can store more files within a file, like pictures etc.
The same is done in *.docx by using ZIP archive instead.
There are packages available on PyPI that can read OLE files. Like (olefile, compoundfiles, ...)
I used compoundfiles package to open *.doc file.
However, in MS Word 97-2000, internal subfiles are not XML or HTML, but binary files.
And as this is not enough, each contains an information about other one, so you have to read at least two of them and unravel stored info accordingly.
To understand fully, read the PDF document from which I took the algorithm.
Code below is very hastily composed and tested on small number of files.
As far as I can see, it works as intended.
Sometimes some gibberish appears at the start, and almost always at the end of text.
And there can be some odd characters in-between as well.
Those of you who just wish to search for text will be happy.
Still, I urge anyone who can help to improve this code to do so.
doc2text module:
"""
This is Python implementation of C# algorithm proposed in:
http://b2xtranslator.sourceforge.net/howtos/How_to_retrieve_text_from_a_binary_doc_file.pdf
Python implementation author is Dalen Bernaca.
Code needs refining and probably bug fixing!
As I am not a C# expert I would like some code rechecks by one.
Parts of which I am uncertain are:
* Did the author of original algorithm used uint32 and int32 when unpacking correctly?
I copied each occurence as in original algo.
* Is the FIB length for MS Word 97 1472 bytes as in MS Word 2000, and would it make any difference if it is not?
* Did I interpret each C# command correctly?
I think I did!

I'm not sure if you're going to have much luck without using COM. The .doc format is ridiculously complex, and is often called a "memory dump" of Word at the time of saving!
At Swati, that's in HTML, which is fine and dandy, but most word documents aren't so nice!
Just an option for reading 'doc' files without using COM: miette. Should work on any platform.

Experts,
I have a template docx report, which has image and standard formatting inside it. What I did using docx, was just to search some tags, and replace it using the value from a config file.
Search & replace was working as expected, but the output file lost all the image, and the formatting. Do you know what went wrong? All I did was just modifying the example-makedocument.py, and replace it to use with my docx file.
I've searched the discussion on python.docx librelist, and their page on github, there were a lot of questions like this, but remained unanswered.
Thank you.
--- my script is simple one like this ---
from docx import *
from ConfigParser import SafeConfigParser
filename = "template.docx"
document = opendocx(filename)
relationships = relationshiplist()
body = document.xpath('/w:document/w:body',namespaces=nsprefixes)[0]
####### get config file
parser = SafeConfigParser()
parser.read('../TESTING1-config.txt')
######## Search and replace
print 'Searching for something in a paragraph ...',
if search(body, ''):
print 'found it!'
else:
print 'nope.'
print 'Replacing ...',
body = advReplace(body, '', parser.get('ASD', 'ASD'))
print 'done.'

Python-docx only copies over the document.xml file in the original Docx zip. Everything else is discarded and recreated either from a function or from a preexisting template file. This unfortunately includes the document.xml.rels file that is responsible for mapping images.
The oodocx module that I have developed copies over everything from the old Docx and, at least in my experience, plays nicely with images.
I have answered to a similar question about python-docx. Python docx is not meant to store the docx images and export them away.
Python Docx is not a templating engine for Docx.
I want to make some simple edits on a Word document, eg replace all TEXT with text.
I have tried python-docx, but it doesn't let me save only my changes. Instead it makes a new document with default style and saves it with my content.
Is there a good library(Python or other languages) that supports quick edits on docx?
Little bit of why you are not able to do simple string replace in docx - a .docx document is a Zip archive in OpenXML format: you have first to uncompress it. Earlier I used to use zip to unzip the docx & then search for the text, like so -
>>> import zipfile
>>> z = zipfile.ZipFile("yourDocInDocx.docx")
>>> "someText" in z.read("word/document.xml")
True
>>> "random other string" in z.read("word/document.xml")
False
>>> z.close()
But later I found this excellent python library for docx - Python-docx which will solve your problem.
# Import the module
from docx import *
# Open the .docx file
document = opendocx('yourDocInDocx.docx')
# Search returns true if found
search(document,'your search string')
