我想使用Python来自动化Acrobat Pro将PDF导出到XML。 我已经使用正在运行的程序中的“另存为”对话框手动尝试过，现在想通过Python脚本来完成。 我已经阅读了许多页面，包括Adobe SDK，SDK论坛，VB论坛的一部分，我没有运气。
我在这里读到Blish的问题： 使用pywin32来控制Adobe Acrobat时出现“未执行”exception
和这个网页：timgolden python / win32_how_do_i / generate-a-static-com-proxy.html
我错过了一些东西。 我的代码是：
import win32com.client import win32com.client.makepy win32com.client.makepy.GenerateFromTypeLibSpec('Acrobat') adobe = win32com.client.DispatchEx('AcroExch.App') avDoc = win32com.client.DispatchEx('AcroExch.AVDoc') avDoc.Open('C:\Documents and Settings\PC\Desktop\a_PDF.pdf', 'C:\Documents and Settings\PC\Desktop') pdDoc = avDoc.GetPDDoc() jObject = pdDoc.GetJSObject() jObject.SaveAs('C:\Documents and Settings\PC\Desktop\a_PDF.xml', "com.adobe.acrobat.xml-1-00") 完整的错误是：
Traceback (most recent call last): File "<pyshell#31>", line 1, in <module> jObject.SaveAs('C:\Documents and Settings\PC\Desktop\a_PDF.xml', "com.adobe.acrobat.xml-1-00") File "C:\Python27\lib\site-packages\win32com\client\dynamic.py", line 511, in __getattr__ ret = self._oleobj_.Invoke(retEntry.dispid,0,invoke_type,1) com_error: (-2147467263, 'Not implemented', None, None)
我猜它与make.py有关，但我不明白如何在我的代码中实现它。
我从我的代码中拉出了这一行，并在运行时得到了相同的错误：
win32com.client.makepy.GenerateFromTypeLibSpec('Acrobat')
然后，我将这两行从“DispatchEX”更改为“Dispatch”，同样的错误：
adobe = win32com.client.Dispatch('AcroExch.App') avDoc = win32com.client.Dispatch('AcroExch.AVDoc')
当我自己运行调度，然后给他们回电，我得到：
>>> adobe = win32com.client.DispatchEx('AcroExch.App') >>> adobe <win32com.gen_py.Adobe Acrobat 10.0 Type Library.CAcroApp instance at 0x18787784> >>> avDoc = win32com.client.Dispatch('AcroExch.AVDoc') >>> avDoc <win32com.gen_py.Adobe Acrobat 10.0 Type Library.CAcroAVDoc instance at 0x20365224>
这是否意味着我只能打一个电话给Dispatch？ 我拉了：
adobe = win32com.client.Dispatch('AcroExch.App')
并得到了同样的错误。
这个Adobe网站说：
AVDoc Product availability: Acrobat, Reader Platform availability: Macintosh, Windows, UNIX Syntax typedef struct _t_AVDoc* AVDoc; A view of a PDF document in a window. There is one AVDoc per displayed document. Unlike a PDDoc, an AVDoc has a window associated with it.
PDDoc页面说：
A PDDoc object represents a PDF document. There is a correspondence between a PDDoc and an ASFile. Also, every AVDoc has an associated PDDoc, although a PDDoc may not be associated with an AVDoc.
我尝试了下面的代码，也得到了同样的错误：
import win32com.client import win32com.client.makepy pdDoc = win32com.client.Dispatch('AcroExch.PDDoc') pdDoc.Open('C:\Documents and Settings\PC\Desktop\a_PDF.pdf') jObject = pdDoc.GetJSObject() jObject.SaveAs('C:\Documents and Settings\PC\Desktop\a_PDF.xml', "com.adobe.acrobat.xml-1-00")
同样的错误，如果我改变：
pdDoc = win32com.client.Dispatch('AcroExch.PDDoc')
至
pdDoc = win32com.client.gencache.EnsureDispatch('AcroExch.PDDoc')
像这里： win32com.client.Dispatch工程，但不是win32com.client.gencache.EnsureDispatch
user2993272，你差不多在这里了：只需要一行代码，你所拥有的代码应该完美无缺地工作。

为了完整起见，这段代码应该可以完成工作，而不需要手动修补dynamic.py（snippet应该可以运行在开箱即用的状态）：

我已经在WinPython x64 2.7.6.3，Acrobat X Pro上测试过了
