How do I extract data from a doc/docx file using Python

问题

I know there are similar questions out there, but I couldn't find something that would answer my prayers. What I need is a way to access certain data from MS-Word files and save it in an XML file. Reading up on python-docx did not help, as it only seems to allow one to write into word documents, rather than read. To present my task exactly (or how i chose to approach my task): I would like to search for a key word or phrase in the document (the document contains tables) and extract text data from the table where the key word/phrase is found. Anybody have any ideas?

回答1:

The docx is a zip file containing an XML of the document. You can open the zip, read the document and parse data using ElementTree.

The advantage of this technique is that you don't need any extra python libraries installed.

import zipfile
import xml.etree.ElementTree

WORD_NAMESPACE = '{http://schemas.openxmlformats.org/wordprocessingml/2006/main}'
PARA = WORD_NAMESPACE + 'p'
TEXT = WORD_NAMESPACE + 't'
TABLE = WORD_NAMESPACE + 'tbl'
ROW = WORD_NAMESPACE + 'tr'
CELL = WORD_NAMESPACE + 'tc'

with zipfile.ZipFile('<path to docx file>') as docx:
    tree = xml.etree.ElementTree.XML(docx.read('word/document.xml'))

for table in tree.iter(TABLE):
    for row in table.iter(ROW):
        for cell in row.iter(CELL):
            print ''.join(node.text for node in cell.iter(TEXT))

To search in a document with python-docx

# Import the module
from docx import *

# Open the .docx file
document = opendocx('A document.docx')

# Search returns true if found    
search(document,'your search string')

You also have a function to get the text of a document:

https://github.com/mikemaccana/python-docx/blob/master/docx.py#L910

# Import the module
from docx import *

# Open the .docx file
document = opendocx('A document.docx')
fullText=getdocumenttext(document)

It seems that pywin32 does the trick. You can iterate through all the tables in a document and through all the cells inside a table. It's a bit tricky to get the data (the last 2 characters from every entry have to be omitted), but otherwise, it's a ten minute code. If anyone needs additional details, please say so in the comments.

A more simple library with image extraction capability.

pip install docx2txt

Then use below code to read docx file.

import docx2txt
text = docx2txt.process("file.docx")
