Python 将PPT里面文字读取出来存为TXT文件

在开发中遇到比较偏门的需求，要讲ppt文件里面的所有文字读取出来并存储为txt文件。我们使用win32com，win32con，win32gui，codecs，pythoncom这几个库来实现该需求，具体代码如下：

# coding:utf-8

import win32com

import win32con

import win32gui

import codecs

from win32com.client import Dispatch

import pythoncom

import os

from os.path import join

import sys

def getLocalEncoding():

u"""取得本地编码"""

import locale

import codecs

# print locale.getpreferredencoding()

return "%s" % codecs.lookup(locale.getpreferredencoding()).name

class MSOffice2txt():

def __init__(self, fileType=['doc', 'ppt']):

self.docCom = None

self.pptCom = None

pythoncom.CoInitialize()

if type(fileType) is not list:

return 'Error, please check the fileType, it must be list[]'

for ft in fileType:

if ft == 'doc':

self.docCom = self.docApplicationOpen()

elif ft == 'ppt':

self.pptCom = self.pptApplicationOpen()

def close(self):

self.docApplicationClose(self.docCom)

self.pptApplicationClose(self.pptCom)

def docApplicationOpen(self):

docCom = Dispatch('Word.Application')

docCom.Visible = 1

docCom.DisplayAlerts = 0

docHwnd = win32gui.FindWindow(None, 'Microsoft Word')

win32gui.ShowWindow(docHwnd, win32con.SW_HIDE)

return docCom

def docApplicationClose(self, docCom):

if docCom is not None:

docCom.Quit()

def doc2Txt(self, docCom, docFile, txtFile):

doc = docCom.Documents.Open(FileName=docFile, ReadOnly=1)

doc.SaveAs(txtFile, 2)

doc.Close()

def pptApplicationOpen(self):

pptCom = Dispatch('PowerPoint.Application')

pptCom.Visible = 1

pptCom.DisplayAlerts = 0

pptHwnd = win32gui.FindWindow(None, 'Microsoft PowerPoint')

win32gui.ShowWindow(pptHwnd, win32con.SW_HIDE)

return pptCom

def pptApplicationClose(self, pptCom):

if pptCom is not None:

pptCom.Quit()

def ppt2txt(self, pptCom, pptFile, txtFile):

ppt = pptCom.Presentations.Open(pptFile, ReadOnly=1, Untitled=0, WithWindow=0)

f = codecs.open(txtFile, "w", 'gb18030')

slide_count = ppt.Slides.Count

for i in xrange(1, slide_count + 1):

shape_count = ppt.Slides(i).Shapes.Count

for j in xrange(1, shape_count + 1):

if ppt.Slides(i).Shapes(j).HasTextFrame:

s = ppt.Slides(i).Shapes(j).TextFrame.TextRange.Text

f.write(s)

f.close()

ppt.Close()

def translate(self, filename, txtFilename):

if filename.endswith('doc') or filename.endswith('docx'):

if self.docCom is None:

self.docCom = self.docApplicationOpen()

self.doc2Txt(self.docCom, filename, txtFilename)

return True

elif filename.endswith('ppt') or filename.endswith('pptx'):

if self.pptCom is None:

self.pptCom = self.pptApplicationOpen()

self.ppt2txt(self.pptCom, filename, txtFilename)

return True

else:

return False

if __name__ == '__main__':

msoffice = MSOffice2txt()

#local_encoding = getLocalEncoding()

#reload(sys)

#sys.setdefaultencoding(getLocalEncoding())

#os.path.dirname(os.path.abspath(__file__))#

dirroot =os.path.dirname(sys.executable)

#dirroot = dirroot.decode(local_encoding)

print 'dirroot:'+dirroot

for root, dirs, files in os.walk(dirroot):

for OneFileName in files :

if OneFileName.endswith('ppt') or OneFileName.endswith('pptx'):

filename = os.path.join(root, OneFileName)

txtname = filename.replace('.ppt','.txt').replace('.pptx','.txt')

if msoffice.translate(filename, txtname):

print filename+' to txt successed! '+txtname

print 'Finished to txt!'

msoffice.close()

os.system('pause')
