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__))#
