• python 如何将ppt和word转化为txt文档


      最近做了关于计算文档中关键词的程序,使用Tf-idf方法去提取,其中需要使用python读取MS word文档和 MS powerpoint中的内容,现将部分讲解和代码贴出来,请指正。

      首先,介绍一下win32com,这是个和window链接的模块,实话说,功能是很强大的,在网上看到很多功能,可以用来打开word,ppt,Excel,Access,模拟浏览器等行为,下载地址:http://starship.python.net/~skippy/win32/Downloads.html,现在,介绍其功能,是从其他网上的资料粘贴过来的。

    1.word功能:http://my.oschina.net/duxuefeng/blog/64137(这个写的比较清楚) 

     1 import win32com
     2 from win32com.client import Dispatch, constants
     3 
     4 w = win32com.client.Dispatch('Word.Application')
     5 # 或者使用下面的方法,使用启动独立的进程:
     6 # w = win32com.client.DispatchEx('Word.Application')
     7 
     8 # 后台运行,不显示,不警告
     9 w.Visible = 0
    10 w.DisplayAlerts = 0
    11 
    12 # 打开新的文件
    13 doc = w.Documents.Open( FileName = filenamein )
    14 # worddoc = w.Documents.Add() # 创建新的文档
    15 
    16 # 插入文字
    17 myRange = doc.Range(0,0)
    18 myRange.InsertBefore('Hello from Python!')
    19 
    20 # 使用样式
    21 wordSel = myRange.Select()
    22 wordSel.Style = constants.wdStyleHeading1
    23 
    24 # 正文文字替换
    25 w.Selection.Find.ClearFormatting()
    26 w.Selection.Find.Replacement.ClearFormatting()
    27 w.Selection.Find.Execute(OldStr, False, False, False, False, False, True, 1, True, NewStr, 2)
    28 
    29 # 页眉文字替换
    30 w.ActiveDocument.Sections[0].Headers[0].Range.Find.ClearFormatting()
    31 w.ActiveDocument.Sections[0].Headers[0].Range.Find.Replacement.ClearFormatting()
    32 w.ActiveDocument.Sections[0].Headers[0].Range.Find.Execute(OldStr, False, False, False, False, False, True, 1, False, NewStr, 2)
    33 
    34 # 表格操作
    35 doc.Tables[0].Rows[0].Cells[0].Range.Text ='123123'
    36 worddoc.Tables[0].Rows.Add() # 增加一行
    37 
    38 # 转换为html
    39 wc = win32com.client.constants
    40 w.ActiveDocument.WebOptions.RelyOnCSS = 1
    41 w.ActiveDocument.WebOptions.OptimizeForBrowser = 1
    42 w.ActiveDocument.WebOptions.BrowserLevel = 0 # constants.wdBrowserLevelV4
    43 w.ActiveDocument.WebOptions.OrganizeInFolder = 0
    44 w.ActiveDocument.WebOptions.UseLongFileNames = 1
    45 w.ActiveDocument.WebOptions.RelyOnVML = 0
    46 w.ActiveDocument.WebOptions.AllowPNG = 1
    47 w.ActiveDocument.SaveAs( FileName = filenameout, FileFormat = wc.wdFormatHTML )
    48 
    49 # 打印
    50 doc.PrintOut()
    51 
    52 # 关闭
    53 # doc.Close()
    54 w.Documents.Close(wc.wdDoNotSaveChanges)
    55 w.Quit()

    2. Excel功能:同上的网址

    3. Access功能:

    1 import win32com.client
    2 oAccess = win32com.client.Dispatch('Access.Application')
    3 DbFile = r'C:UsershansDocumentsNewDb.mdb'
    4 dbLangGeneral = ';LANGID=0x0409;CP=1252;COUNTRY=0'
    5 # dbVersion40 64
    6 dbVersion = 64
    7 oAccess.DBEngine.CreateDatabase(DbFile, dbLangGeneral, dbVersion)
    8 oAccess.Quit()
    9 del oAccess

    4. 模拟浏览器行为:http://www.cnblogs.com/chenzehe/archive/2010/09/01/1814397.html
