我有一长串复杂的字符串，需要从中提取几个值。我已经能够为其中的大多数创建RegEx，但有一种类型我特别有问题。我已经看了几个类似的问题，但到目前为止没有一个成功。
以下是列表：

我需要创建两个捕获。第一个是防病毒操作，它是AV:后面的值。例如：

AV:Unable to upload file
AV:Unable to delete file
AV:File quarantined
AV:File passed

我需要：

Unable to upload file
Unable to delete file
File quarantined
File passed

以及可能发生的任何其他动作
另一部分是恶意软件的名称，它紧跟在操作之后，并由管道包围|：

Trojan.Win64.SHELMA.SMB1
TROJ_GEN.R002C0DKG22
Troj.Win32.TRX.XXPE50FFF063
TSC_GENCLEAN

以及可能出现的任何其他恶意软件名称。
这是我其中一次失败的尝试

pattern = '(AV:)(?s)(.*?)\|'
a = [re.search(pattern,m) for m in malware]
print(a)

看起来这是您想要的模式，但不确定该模式是否适用于您的所有数据：

pattern = 'AV:(?s)(.*)\|3\|'
var = [re.findall(pattern,m)[0] for m in malware]
var = [v.split('|') for v in var]
print(var)

我建议将每一行分解成一个可用的结构（eidogg. dictionary），然后使用它进行进一步的处理。
例如

import re

parsed = [ line.split("|") for line in malware ]
for i, (ts,*parts,attributes) in enumerate(parsed):
    *ts,url,cef = ts.split(" ")
    parsed[i] = { "ts":" ".join(ts), "url":url, "CEF":cef.split(":")[-1] }
    parsed[i].update( zip(["brand","vendor","year","message","virus"],parts) )
    iAttr = iter(re.split(r'(\b\w+\=)',attributes)[1:])
    parsed[i].update( (k[:-1],v.strip()) for k,v in zip(iAttr,iAttr) )
  • 看起来这些行是由不同来源的组件使用不同的分隔符组成的（管道在最后一级使用）。您可以根据需要进一步分解每个部分。*

输出：

import json
for i,d in enumerate(parsed):
    print("at index",i)
    print(json.dumps(d,indent=4))
