python - 如何解析复杂的字符串

Question

我正在尝试解析以下字符串（实际上这是一个列表，无论如何......）。

我想在这里使用 re 但也许有一个简单的解决方案？我的大脑今天看到了太多的代码。

如果所有信息都存储在单个 dict() 中，那将是最好的

{'title1': 
    {'duration': '02:06:44', 
     'audio_tracks': 
         [{'1': 'English (AC3) (5.1 ch) (iso639-2: eng), 48000Hz, 384000bps' },
         {'2': 'English (AC3) (Dolby Surround) (iso639-2: eng), 48000Hz, 192000bps' },
         ...]},
     'subtitle_tracks':
         [{'1': 'English (iso639-2: eng) (Bitmap)(VOBSUB)' },
         {'2': 'Deutsch (iso639-2: deu) (Bitmap)(VOBSUB)' },
         ...]},
     }
}

像这样的东西。也许有人有一些提示如何解析：

+ something:
    + some: info,
    + something:,
        + 1: indented information

事物？

我有这个用于各种目的的缩进文本解析器。在这里，我将其调整为 ffmpeg 格式：

import sys
import re

root = ['root', []]
path = [root]
last_indent = -1
for line in sys.stdin:
    line = line.rstrip()
    if not line:
        break

    # calculate indent
    iline = line
    line = line.lstrip(' ')
    indent = (len(iline) - len(line))/2

    line = line.lstrip('+ ')
    bits = re.split('[:,]', line, 1)
    key = bits[0]
    try:
        content = bits[1].strip()
    except IndexError:
        content = None

    if not content:
        # root node
        content = []

    if indent <= last_indent:
        del path[indent - last_indent - 1:]
    cur = [key, content]
    path[-1][-1].append(cur)
    path.append(cur)
    last_indent = indent

pprint(root)

输出：

您必须针对所需的输出对其进行调整，但这应该给您一个开始。

http://ffmpeg.org/ffprobe.html和https://reviews.handbrake.fr/r/224/都解决了。

所以我想出了自己的解析算法。在这里（l 必须是一个 list() - 只需将 Handbrake 输出除以 '\n'）：

解析 HandBrakeCLI 输出

def getHandBrakeInformation(l):
    currentTitle = None
    titleDict = {}
    returnDict = {}
    for line in l:
        if line.startswith('+ title'):
            titleNum = line.rstrip(':').split(' ')
            currentTitle = "%s_%s" % (titleNum[1], titleNum[2])
            titleDict[currentTitle] = []
            returnDict[currentTitle] = {}
        else:
            titleDict[currentTitle].append(line[2:])

    currentTrack = None
    for title in titleDict:
        for key in titleDict[title]:
            if key.startswith('+ duration:'):
                duration = key.split(' ')
                duration = duration[2]
                returnDict[title]['duration'] = duration
                titleDict[title].remove(key)
            elif key.startswith('+ audio') or key.startswith('+ subtitle'):
                currentTrack = key[2:-1].replace(' ', '_')
                returnDict[title][currentTrack] = {}
            elif currentTrack is not None and not key.startswith('+'):
                currentTrackValueSplit = key[4:].split(',', 1)
                returnDict[title][currentTrack][currentTrackValueSplit[0].strip()] = currentTrackValueSplit[1].strip()
            else:
                currentTrack = None
    return returnDict

这里是输出：
