Wikitext到HTML的正则表达式[关闭]

Question

I am Tryting to show wiki text in HTML in my app(Using cakephp). I use this expression for <h4>,<h5>,<h6>

'/^==== (.*) ====$/'
    =>  '<h4>\1</h4>',
    '/^===== (.*) =====$/'
    =>  '<h5>\1</h5>',
    '/^====== (.*) ======$/'
    => '<h6>\1</h6>',

[http://www.wikipedia.org Wikipedia] will be shown as <ahref="www.wikipedia.org">Wikipedia </a>

[5|Text] will show like <a href="http://fillpage/5/page_slug">Text</a>

[[6#HeadingB|Text ]] will shown as <ahref="http://fillpage/6/page_slug#HeadingB>Text</a>

[[6#HeadingB]] will shown as <a href="http://fillpage/5/page_slug">PageTitle</a>

[media:631|Description|Position] will shown as <img class="position" src="http://fullpath/lang_code/631.jpg">Description

I wan't to know how to make such regex for links(exactly like Wikipedia shows.) how to make it done. And how to match space b/w two brackets for links.

Answer 1

Match \[(.*?) +(.*)\]

and replace with : $2

or if you're using preg in php

Go for this:

'/\[(.*?) +(.*)]$/'

and accept them with backslash like so : '<a href="\1">\2</a>' within an array as the value to the pattern above as a key.

That was up for wikipedia. You can go to http://gskinner.com/RegExr/ and use the pattern references on the right column.

Hope it helps.
