这里测试的环境是：windows xp,office 2007,python 2.5.2,pywin32 build

213，原理是利用win32com接口直接调用office

API，好处是简单、兼容性好，只要office能处理的，python都可以处理，处理出来的结果和office word里面“另存为”一致。

#!/usr/bin/env python

#coding=utf-8

from

win32com import

client as

wc

word = wc.Dispatch

(

'Word.Application'

)

doc = word.Documents

.Open

(

'd:/labs/math.doc'

)

doc.SaveAs

(

'd:/labs/math.html'

, 8

)

doc.Close

(

)

word.Quit

(

)

关键的就是doc.SaveAs(‘d:/labs/math.html’,

8)这一行，网上很多文章写成：doc.SaveAs(‘d:/labs/math.html’,

win32com.client.constants.wdFormatHTML)，直接报错：

AttributeError: class Constants has no attribute ‘wdFormatHTML’

当然你也可以用上面的代码将word文件转换成任意格式文件(只要office 2007支持，比如将word文件转换成PDF文件，把8改成17即可)，下面是office 2007支持的全部文件格式对应表：

wdFormatDocument = 0

wdFormatDocument97 = 0

wdFormatDocumentDefault = 16

wdFormatDOSText = 4

wdFormatDOSTextLineBreaks = 5

wdFormatEncodedText = 7

wdFormatFilteredHTML = 10

wdFormatFlatXML = 19

wdFormatFlatXMLMacroEnabled = 20

wdFormatFlatXMLTemplate = 21

wdFormatFlatXMLTemplateMacroEnabled = 22

wdFormatHTML = 8

wdFormatPDF = 17

wdFormatRTF = 6

wdFormatTemplate = 1

wdFormatTemplate97 = 1

wdFormatText = 2

wdFormatTextLineBreaks = 3

wdFormatUnicodeText = 7

wdFormatWebArchive = 9

wdFormatXML = 11

wdFormatXMLDocument = 12

wdFormatXMLDocumentMacroEnabled = 13

wdFormatXMLTemplate = 14

wdFormatXMLTemplateMacroEnabled = 15

wdFormatXPS = 18

照着字面意思应该能对应到相应的文件格式，如果你是office

2003可能支持不了这么多格式。word文件转html有两种格式可选wdFormatHTML、wdFormatFilteredHTML(对应数字

8、10)，区别是如果是wdFormatHTML格式的话，word文件里面的公式等ole对象将会存储成wmf格式，而选用

wdFormatFilteredHTML的话公式图片将存储为gif格式，而且目测可以看出用wdFormatFilteredHTML生成的HTML

明显比wdFormatHTML要干净许多。

当然你也可以用任意一种语言通过com来调用office API，比如PHP.

=========================================

使用 python 写 COM

2009年09月03日 星期四 下午 07:01

Python 支持Com调用(client com) 以及撰写COM 组件(server com).

1. com 调用示例(使用Windows Media Player 播放音乐)

from

win32com.client

import

Dispatch

mp

=

Dispatch(

"

WMPlayer.OCX

"

)

tune

=

mp.newMedia(

"

C:/WINDOWS/system32/oobe/images/title.wma

"

)

mp.currentPlaylist.appendItem(tune)

mp.controls.play()

class

PythonUtilities:

_public_methods_

=

[

'

SplitString

'

]

_reg_progid_

=

"

PythonDemos.Utilities

"

#

NEVER copy the following ID

#

Use "print pythoncom.CreateGuid()" to make a new one.

_reg_clsid_

=

"

{41E24E95-D45A-11D2-852C-204C4F4F5020}

"

def

SplitString(self, val, item

=

None):

import

string

if

item

!=

None: item

=

str(item)

return

string.split(str(val), item)

#

Add code so that when this script is run by

#

Python.exe, it self-registers.

if

__name__

==

'

__main__

'

:

print

"

Registering COM server

"

import

win32com.server.register

win32com.server.register.UseCommandLine(PythonUtilities)

- 注册/注销Com

Command-Line Option

Description

The default is to register the COM objects.

--unregister

Unregisters the objects. This removes all references to the objects from the Windows registry.

--debug

Registers the COM servers in debug mode. We discuss debugging COM servers later in this chapter.

--quiet

Register (or unregister) the object quietly (i.e., don't report success).

- 使用COM

可以在python 命令行下运行

>>>

import

win32com.client

>>>

s

=

win32com.client.Dispatch(

"

PythonDemos.Utilities

"

)

>>>

s.SplitString(

"

a,b,c

"

,

"

,

"

)

((u

'

a

'

, u

'

a,b,c

'

),)

>>>

3. python server com 原理

其实在注册表中查找到python com 的实现内幕

inproc server 是通过pythoncom25.dll 实现

local server 通过localserver.py 实现

com 对应的python 源文件信息在 PythonCOMPath & PythonCOM

4. 使用问题

用PHP 或者 c 调用com 的时候

php

$com

=

new

COM(

"

PythonDemos.Utilities

"

);

$rs

=

$com

->

SplitString(

"

a b c

"

);

foreach

(

$rs

as

$r

)

echo

$r

.

"

/n

"

;

?>

会碰到下面的一些错误.

pythoncom error: PythonCOM Server - The 'win32com.server.policy' module could not be loaded.

: No module named server.policy

pythoncom error: CPyFactory::CreateInstance failed to create instance.

(80004005)

可以通过2种方式解决:

a. 设置环境 PYTHONHOME = D:/usr/Python

另外在c ++ 使用python 的时候, 如果import module 出现错误'import site' failed; use -v for traceback

的话, 也可以通过设置这个变量解决.

b. 为com 生产exe, dll 可执行文件, setup.py 代码如下 :

from

distutils.core

import

setup

import

py2exe

import

sys

import

shutil

#

Remove the build tree

ALWAYS do that!

shutil.rmtree(
