从MS Word提取数据

Question

I am looking for a way to extract / scrape data from Word files into a database. Our corporate procedures have Minutes of Meetings with clients documented in MS Word files, mostly due to history and inertia.

I want to be able to pull the action items from these meeting minutes into a database so that we can access them from a web-interface, turn them into tasks and update them as they are completed.

Which is the best way to do this:

1. VBA macro from inside Word to create CSV and then upload to the DB?
2. VBA macro in Word with connection to DB (how does one connect to MySQL from VBA?)
3. Python script via win32com then upload to DB?

The last one is attractive to me as the web-interface is being built with Django, but I've never used win32com or tried scripting Word from python.

EDIT: I've started extracting the text with VBA because it makes it a little easier to deal with the Word Object Model. I am having a problem though - all the text is in Tables, and when I pull the strings out of the CELLS I want, I get a strange little box character at the end of each string. My code looks like:

sFile = "D:\temp\output.txt"
fnum = FreeFile
Open sFile For Output As #fnum

num_rows = Application.ActiveDocument.Tables(2).Rows.Count

For n = 1 To num_rows
    Descr = Application.ActiveDocument.Tables(2).Cell(n, 2).Range.Text
    Assign = Application.ActiveDocument.Tables(2).Cell(n, 3).Range.Text
    Target = Application.ActiveDocument.Tables(2).Cell(n, 4).Range.Text
    If Target = "" Then
        ExportText = ""
    Else
        ExportText = Descr & Chr(44) & Assign & Chr(44) & _
            Target & Chr(13) & Chr(10)
        Print #fnum, ExportText
    End If
Next n

Close #fnum

What's up with the little control character box? Is some kind of character code coming across from Word?

Answer 1

Word has a little marker thingy that it puts at the end of every cell of text in a table.

It is used just like an end-of-paragraph marker in paragraphs: to store the formatting for the entire paragraph.

Just use the Left() function to strip it out, ie

 Left(Target, Len(Target)-1))

By the way, instead of

 num_rows = Application.ActiveDocument.Tables(2).Rows.Count
 For n = 1 To num_rows
      Descr = Application.ActiveDocument.Tables(2).Cell(n, 2).Range.Text

Try this:

 For Each row in Application.ActiveDocument.Tables(2).Rows
      Descr = row.Cells(2).Range.Text

Answer 2

Well, I've never scripted Word, but it's pretty easy to do simple stuff with win32com. Something like:

from win32com.client import Dispatch
word = Dispatch('Word.Application')
doc = word.Open('d:\\stuff\\myfile.doc')
doc.SaveAs(FileName='d:\\stuff\\text\\myfile.txt', FileFormat=?)  # not sure what to use for ?

This is untested, but I think something like that will just open the file and save it as plain text (provided you can find the right fileformat) – you could then read the text into python and manipulate it from there. There is probably a way to grab the contents of the file directly, too, but I don't know it off hand; documentation can be hard to find, but if you've got VBA docs or experience, you should be able to carry them across.

Have a look at this post from a while ago: http://mail.python.org/pipermail/python-list/2002-October/168785.html Scroll down to COMTools.py; there's some good examples there.

You can also run makepy.py (part of the pythonwin distribution) to generate python "signatures" for the COM functions available, and then look through it as a kind of documentation.

Answer 3

You could use OpenOffice. It can open word files, and also can run python macros.

Answer 4

我想说一下右侧的相关问题-> 顶部的似乎对使用python路线有一些好主意。

Answer 5

how about saving the file as xml. then using python or something else and pull the data out of word and into the database.

Answer 6

It is possible to programmatically save a Word document as HTML and to import the table(s) contained into Access. This requires very little effort.
