使用python熊貓讀取.reg文件

Question

我有一些.reg文件來自我想用python熊貓解析的幾臺機器。

如果換行開頭[它是，如果換行開始爲下面的項目

路徑以」新生產線，以等號是開始時的產品與通路的關鍵是是它

以上如果該行包含一個：且不是路徑，=符號後的項目和冒號之前被認爲是類型

如果沒有類型，比後的項等號是值

if該類型包含十六進制，而不是在需要將其添加到完整鍵值之後的行中，而沒有在數據框中的一行上基本上具有十六進制的反斜槓。

數據集如下所示，在實際的文件更：

我怎樣才能得到數據幀閱讀，如果有空白與所有的路徑，鑰匙，類型和值隱含加入NONE如下？實施例（不包括數據集由於尺寸）如下：

[HKEY_CURRENT_CONFIG\Software\Fonts] LogPixel2s   dword  00000070

這個解決方案最終更加優雅和快速處理多個hklm文件。

newlist = [] 
for section in config.sections(): 
    for (key, val) in config.items(section): 
     newlist.append([section, key, val]) 

df = pd.DataFrame(newlist) 




      Path     Name                    Data 
    HKEY_LOCAL_MACHINE\SOFTWARE\Classes\ActivatableClasses\Package\EnvironmentsA...  "ActivationType"                 dword:00000000 
    HKEY_LOCAL_MACHINE\SOFTWARE\Classes\ActivatableClasses\Package\EnvironmentsA...     "CLSID"           "{12345665-3CFA-4322-F36F-9880D9BF5604}"

嘗試這種情況：

import re 
import io 
from configparser import ConfigParser 
import pandas as pd 


def read_reg(filename, encoding='utf-16'): 
    with io.open(filename, encoding=encoding) as f: 
     data = f.read() 
    # get rid of non-section strings in the beginning of .reg file 
    data = re.sub(r'^[^\[]*\n', '', data, flags=re.S) 
    cfg = ConfigParser(strict=False) 
    # dirty hack for "disabling" case-insensitive keys in "configparser" 
    cfg.optionxform=str 
    cfg.read_string(data) 
    data = [] 
    # iterate over sections and keys and generate `data` for pandas.DataFrame 
    for s in cfg.sections(): 
     if not cfg[s]: 
      data.append([s, None, None, None]) 
     for key in cfg[s]: 
      tp = val = None 
      if cfg[s][key]: 
       # take care of value type 
       if ':' in cfg[s][key]: 
        tp, val = cfg[s][key].split(':') 
       else: 
        val = cfg[s][key].replace('"', '').replace(r'\\\n', '') 
      data.append([s, key.replace('"', ''), tp, val]) 
    df = pd.DataFrame(data, columns=['Path','Key','Type','Value']) 
    # make `hex` values "one-line" 
    df.loc[df.Type.notnull() & df.Type.str.contains(r'^hex'), 'Value'] = \ 
     df.loc[df.Type.notnull() & df.Type.str.contains(r'^hex'), 'Value'].str.replace(r'\\\n','') 
    return df 

filename = '/path/to/regfile.reg'  
# NOTE: you might have to specify the encoding: example: `encoding='utf-8-sig'`, default: 'utf-16' - default for Windows Registry files 
df = read_reg(filename) 
print(df.loc[df.Path.str.contains(r'Software\\(?:Fonts|S)')]) 

結果：

In [236]: print(df.loc[df.Path.str.contains(r'Software\\(?:Fonts|S)')]) 
           Path   Key Type  Value 
7 HKEY_CURRENT_CONFIG\Software\Fonts LogPixels dword 00000060 
8 HKEY_CURRENT_CONFIG\Software\Fonts LogPixel2s dword 00000070 
9  HKEY_CURRENT_CONFIG\Software\S  None None  None 

十六進制值：

In [45]: df.loc[df.Type.notnull() & df.Type.str.contains(r'^hex'), 'Value'] 
Out[45]: 
3  01,00,00,00,d0,8c,9d,df,01,15,d1,11,8c,7a,00,c0,4f,c2,97,eb,01,00,00,00,db,b0,ca,53,b8,b8,23,4c,80,98,d7,99,bf,60,50,ce,04,00,00,00,02 
,00,00,00,00... 
10 32,00,35,00,62,00,36,00,65,00,62,00,36,00,34,00,2d,00,65,00,30,00,65,00,32,00,2d,00,34,00,65,00,33,00,62,00,2d,00,38,00,32,00,64,00,36 
,00,2d,00,64... 
Name: Value, dtype: object 

In [46]: df.loc[df.Type.notnull() & df.Type.str.contains(r'^hex'), 'Value'].str.len() 
Out[46]: 
3  737 
10 221 
Name: Value, dtype: int64 

注：我沒有實現任何錯誤處理 - 這生產代碼可能是必需的。所以你可能想要實現它...
