regex - Python regular expression with wiki text -

-

i'm trying change wikitext normal text using python regular expressions substitution. there 2 formatting rules regarding wiki link.

  • [[name of page]]

  • [[name of page | text display]]

    (http://en.wikipedia.org/wiki/wikipedia:cheatsheet)

here text gives me headache.

the cd composed entirely of [[cover version]]s of [[the beatles]] songs george martin [[record producer|produced]] originally.

the text above should changed into:

the cd composed entirely of cover versions of beatles songs george martin produced originally.

the conflict between [[ ]] , [[ | ]] grammar main problem. don't need 1 complex regular expression. applying multiple (maybe two) regular expression substitution(s) in sequence ok.

please enlighten me on problem.

wikilink_rx = re.compile(r'\[\[(?:[^|\]]*\|)?([^\]]+)\]\]') return wikilink_rx.sub(r'\1', the_string)

example: http://ideone.com/7oxuz

note: may find mediawiki parsers in http://www.mediawiki.org/wiki/alternative_parsers.

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

(in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
