正则表达式用于隔离字符串的特定部分

Regex expression to isolate particular part of string

我正在努力寻找正确的正则表达式返回:

'industry =[[Banking]], [[Financial services]] |products = [[Investment Banking]]'

<?php
$x =  '[[Basel]] |key_people = [[Axel A. Weber]] (Chairman){{br}}[[Sergio  
Ermotti]] (CEO) {{br}} |area_served = Worldwide |industry =[[Banking]],   
[[Financial services]] |products = [[Investment Banking]]';
';
?>

使用preg_match来修饰|分隔文本的最后两部分

preg_match('~(?<='|)[^|]*'|[^|]*$~', $str);
