如何在Python中解析Windows INF文件？

Question

请帮帮我。

示例的inf文件内容是：

我该怎么解析并格式化这一行 "%iBKDGM% = i845GM, PCI\VEN_8086&DEV_2562&SUBSYS_01491028" 呢？

Answer 1

无论是configparser还是configobj，它们都不能直接解析INF文件。

1. 如果使用configparser，会出现以下错误：

configparser.DuplicateOptionError: While reading from 'Intel.inf' [line 49]: 
option '%i830m%' in section 'Intel.Mfg' already exists

2. 如果使用ConfigObj，会出现以下错误：

configobj.ConfigObjError: Parsing failed with several errors.
First error at line 2.

一个解决办法是使用wininfparser

import sys
from wininfparser import WinINF, INFsection

InfFile = WinINF()
InfFile.ParseFile("/path_to/Intel.inf")

s=InfFile['Intel.Mfg']
if s is None:
    print("Error: section not found!")
    sys.exit(-10)

s.SetKeyAutoSize(False)

s["%iBKDGM%"]="i845GM, PCI\VEN_8086&DEV_2562&SUBSYS_01491028"
# or
# s.AddData("%iBKDGM%","i845GM, PCI\VEN_8086&DEV_2562&SUBSYS_01491028")
InfFile.Save()

结果是Intel.inf

............

[Intel.Mfg]

%iBKDG% = i845G, PCI\VEN_8086&DEV_2562&SUBSYS_01461028
%iBKDG% = i845G, PCI\VEN_8086&DEV_2562&SUBSYS_03031028
%iBKDGM% = i845GM, PCI\VEN_8086&DEV_2562&SUBSYS_01491028

你可以试试内置的 ConfigParser。

http://docs.python.org/library/configparser.html

还有 ConfigObj 这个工具。

http://code.google.com/p/configobj/

这两个工具都说可以处理 Windows 的 INI 文件。
