删除Python中的嵌套bbcode引号？

我试图搜索这个，但只找到了PHP的答案。我正在谷歌应用程序引擎上使用Python，并试图删除嵌套的引号

例如：

[quote user2]
[quote user1]Hello[/quote]
World
[/quote]

我想运行一些东西来获取最外层的报价

[quote user2]World[/quote]

您应该在Python中找到并使用真正的BBCode解析器。谷歌搜索会带来一些点击-例如，和。

不确定您是否只想删除引号，或者删除带有嵌套引号的整个输入。此pyparsing示例执行以下两项操作：

stuff = """
Other stuff
[quote user2] 
[quote user1]Hello[/quote] 
World 
[/quote] 
Other stuff after the stuff
"""

from pyparsing import (Word, printables, originalTextFor, Literal, OneOrMore, 
    ZeroOrMore, Forward, Suppress)

# prototype username
username = Word(printables, excludeChars=']')

# BBCODE quote tags
openQuote = originalTextFor(Literal("[") + "quote" + username + "]")
closeQuote = Literal("[/quote]")

# use negative lookahead to not include BBCODE quote tags in tbe body of the quote
contentWord = ~(openQuote | closeQuote) + (Word(printables,excludeChars='[') | '[')
content = originalTextFor(OneOrMore(contentWord))

# define recursive definition of quote, suppressing any nested quotes
quotes = Forward()
quotes << ( openQuote + ZeroOrMore( Suppress(quotes) | content ) + closeQuote )

# put separate tokens back together
quotes.setParseAction(lambda t : '\n'.join(t))

# quote extractor
for q in quotes.searchString(stuff):
    print q[0]

# nested quote stripper
print quotes.transformString(stuff)

-1：没有表现出研究的努力。你试过什么？堆栈溢出不是来帮你完成所有工作的。@ChrisMorgan:我觉得你太苛刻了，请阅读：哦，我实际上在使用第一个！但是当我测试它的时候，引用一直在继续。我不认为它能够解决这个问题，我会检查一下。

[quote user2]
World
[/quote]

Other stuff
[quote user2]
World
[/quote] 
Other stuff after the stuff
