我开发了一个自定义系统来模拟网络活动，例如下载文件等。我还有一个自定义文件格式可以输入这个系统。我希望将这个用 perl 编写的旧系统更改为 python 中的新系统。但首先我必须以某种方式解析文件。

我想解析文件中的某些字段，例如[settings]我对系统有任何争论的地方。我还有一个[macro]部分是重要内容（步骤等）的开始。

我遇到的麻烦是解析这些部分让我的系统以不同且更简单的格式将其写出（我有数千个这些文件，我只想编写一个生成器来获取旧文件并以新格式写入新文件）。

旧格式：

[settings]
email_to=people
special_websurf_processing=1
period_0_1_only=1
crc_recheck=0

[macro]
%::WebSurfRules =
    (
    'Step1' =>
        {
        action                  => 'NAVIGATE',
        inputstring             => 'http://www.tda-sgft.com/TdaWeb/jsp/fondos/Fondos.tda',
        },
    'Step2' =>
        {
        action        => 'CLICK_REFERENCE',
        matchtype     => 'OUTER',
        matchstring   => 'phHttpDest->\{\'FirstClick\'\}',
        pass          => 'phHttpDest->\{\'Step2Pass\'\}',
        },
    'Step3' =>
        {
        action        => 'CLICK_REFERENCE',
        matchtype     => 'OUTER',
        matchstring   => 'phHttpDest->\{\'SecondClick\'\}',
        },
    'Step4' =>
        {
        action        => 'CLICK_REFERENCE',
        matchtype     => 'OUTER',
        matchstring   => 'phHttpDest->\{\'DealClick\'\}',
        accept_multi_match  => 'ANY_TOP_FIRST',
        },
    'Step5' =>
        {
        action        => 'CLICK_REFERENCE',
        matchtype     => 'INNER',
        matchstring   => 'phHttpDest->\{\'LinkClick2\'\}',
        fail          => 'Step6',
    #    accept_multi_match  => 'ANY_TOP_LAST',
        },
    'Step6' =>
        {
        action        => 'CLICK_REFERENCE',
        matchtype     => 'INNER',
        matchstring   => 'phHttpDest->\{\'DocClick\'\}',
        },
    'Step7' =>
        {
        action                  => 'CLICK_DOWNLOAD_OK',
        },
    );

每次点击 phHttpDest 和操作都与该[data]部分的标题相关。

因此，一种方法是使用一组正则表达式替换来创建新格式的文件。我没有完全理解你的格式规则，所以我通常实现了整个事情，但有一些差异。您必须进入并进行一些调整以对其进行微调。output.txt 文件是使用您的示例作为 input.txt 时生成的文件

代码

import re
data = open('input.txt').read()
data = re.sub(r"    'Step([0-9]+)' =>\s+{\s+action\s+=> ", r"    '\1'     => ", data)
data = re.sub(r"',\s+pass\s+[^,]+,", "", data)
data = re.sub(r"',\s+accept_multi_match\s+[^,]+,", "", data)
data = re.sub(r"\n +#.*\n", "\n", data)
data = re.sub(r"',\s+fail\s+[^,]+,", "", data)
data = re.sub(r"',\s+matchtype\s+[^,]+,", "", data)
data = re.sub(r"',\s+inputstring\s+=> '", ",", data)
data = re.sub(r"\s+matchstring\s+=> '", ",", data)
data = re.sub(r"\n        },", "',", data)
open('output.txt', 'w').write(data)

输出.txt
