여기에는 간단한 정규 표현이 필요합니다

Question

나는 마침내 Wikipedias Wiki 텍스트를 통해 구문 분석하고 있습니다. 여기에는 다음 유형의 텍스트가 있습니다.

{{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]]

패턴으로 시작하는 단일 배열로 모든 라인을 검색해야합니다.

* '''

나는 정기적 인 표현이 여기서 주문하도록 부름을받을 것이라고 생각하지만, 나는 정기적 인 표현 부분에 정말로 엉망이된다.

또한 다른 예에서는 다음 텍스트가 있습니다.

정규 표현에 관해서는 완전히 길을 잃었고 여기서 도움을 사용할 수 있습니다. PHP를 사용하고 있습니다.

Answer 1

I need to extract the infobox ...

Try this, this time making sure dotall mode is enabled:

\{\{Infobox.*?(?=\}\} <!-- Infobox ends -->)

And again, explanation for that:

(?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

This will match upto (but excluding) the the ending expression - you could remove the lookahead itself and include just the contents to have it include the ending, if necessary.

Update, based on comment to answer:

\{\{Infobox.*?(?=\n\}\}\n)

Same as above, but lookahead looks for two braces on their own line.

To optionally allow the comment also, use:

\{\{Infobox.*?(?=\n\}\}(?: <!-- Infobox ends-->)?\n)

Answer 2

MediaWiki is open-source. Have a look at their source code ... ;-)

Answer 3

I think the best way is to merge all lines into one string, especially for the infobox.

Then something along the lines of

$reg = "\n(\* '''[^\n]*)";

for the first part (everything after a new line that start with * ''' and is not a new line).

And for the second part I'm not quire sure right now, but this is a nice place to play around a bit: http://www.solmetra.com/scripts/regex/index.php

And here is a short reference for regular expression syntax: http://www.regular-expressions.info/reference.html

Answer 4

I need to retrieve all lines in a single array which start with the pattern * '''

Enable multiline mode and ensure dotall mode is disabled, and use this:

^\* '''.*$

That expression dissected is:

(?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
