我终于通过wikipedias wiki文本解析了。我在这里有以下类型的文字:
{{Airport-list|the Solomon Islands}}
* '''AGAF''' (AFT) – [[Afutara Airport]] – [[Afutara]]
* '''AGAR''' (RNA) – [[Ulawa Airport]] – [[Arona]], [[Ulawa Island]]
* '''AGAT''' (ATD) – [[Uru Harbour]] – [[Atoifi]], [[Malaita]]
* '''AGBA''' – [[Barakoma Airport]] – [[Barakoma]]
我需要检索以模式
开头的单个数组中的所有行* '''
我认为这里会调用一个正则表达式,但我真的搞砸了我的正则表达式部分。
另外在另一个例子中,我有以下文字:

'''Doha''' ({{lang-ar|الدوحة}}, ''{{transl|ar|ad-Dawḥa}}'' or ''{{unicode|ad-Dōḥa}}'') is the [[capital city]] of [[Qatar]]. It has a population of 400,051 according to the 2005 census,<ref name="autogenerated1">[http://www.hotelrentalgroup.com/Qatar/Sheraton%20Doha%20Hotel%20&%20Resort.htm Sheraton Doha Hotel & Resort | Hotel discount bookings in Qatar<!-- Bot generated title -->]</ref> and is located in the [[Ad Dawhah]] municipality on the [[Persian Gulf]]. Doha is Qatar's largest city, with over 80% of the nation's population residing in Doha or its surrounding [[suburbs]], and is also the economic center of the country.
It is also the seat of government of Qatar, which is ruled by [[Sheikh Hamad bin Khalifa Al Thani]]–the current ruling Emir of Qatar.
我需要在这里提取信息框。信息框是并且包括第一次出现
之间的所有文本{{Infobox Settlement
并以第一次出现
结束}} <!-- Infobox ends -->
在谈到正则表达式时我完全迷失了,我可以在这里使用帮助。我正在使用Php。
我一直在争斗40个小时,我无法让愚蠢的正则表达式正常工作:(到目前为止我只是有这个:
{{信息框[^ \ B(\ r | \ n)}}(\ r | \ n)的\ B] * [\ B(\ r | \ n)}}(\ r | \ n)的( \ r | \ n)的\ b]
但它无法正常工作我希望它能读取{{infobox并以\ n}}结尾的所有字符串数据\ n
我正在使用Php并且不能让它工作:(它只是返回第一次出现}}忽略了我希望它用前面的换行检索}}的事实。请在我浪费更多我的帮助之前请帮助对此的理智:'(

我需要提取信息框...
尝试这一点,这一次确保dotall模式启用:
\{\{Infobox.*?(?=\}\} <!-- Infobox ends -->)
再次,解释:
(?xs) # x=comment mode, s=dotall mode
\{\{ # two opening braces (special char, so needs escaping here.)
Infobox # literal text
.*? # any char (including newlines), non-greedily match zero or more times.
(?= # begin positive lookahead
\}\} # two closing braces
<!-- Infobox ends --> # literal text
) # end positive lookahead
这将匹配(但不包括)结束表达式 - 如果需要,您可以删除前瞻本身并仅包含内容以使其包含结尾。
更新,根据评论回答:
\{\{Infobox.*?(?=\n\}\}\n)
与上面相同,但是lookahead会在自己的行上查找两个大括号。
要选择同时允许评论,请使用:
\{\{Infobox.*?(?=\n\}\}(?: <!-- Infobox ends-->)?\n)

我认为最好的方法是将所有行合并为一个字符串,尤其是对于信息框。
然后是
的内容$ reg =“\ n(\ *'''[^ \ n] *)”;
表示第一部分(以*'''开头并且不是新行的新行之后的所有内容。)
对于第二部分我现在不确定,但这是一个很好的地方玩一下: http://www.solmetra.com/scripts/regex/index.php

我需要检索以模式
开头的单个数组中的所有行* '''
启用多线模式并确保dotall模式禁用,并使用此功能:
^\* '''.*$
解剖的表达是:
(?xm-s) # Flags:
# x enables comment mode (spaces ignore, hashes start comments)
# m enables multiline mode (^$ match lines)
# -s disables dotall (. matches newline)
^ # start of line
\* # literal asterisk
[ ] # literal space (needs braces in comment mode, but not otherwise)
''' # three literal apostrophes
.* # any character (excluding newline), greedily matched zero or many times.
$ # end of line
