Regular expressions help

Try this:

1. For [node=120| Lorem Ipsum]:
   • Pattern: /\[(.*?)\s*\=\s*(.*?)\s*\|\s*(.*?)\s*\]/ (basically /\[(.*?)\=(.*?)\|(.*?)\]/, but \s* here used to ignore spaces)
   • Replacement (no php): <a href="$1/$2">$3</a>
2. For [piece| Lorem Ipsum]:
   • Pattern: /\[\s*(.*?)\s*\|\s*(.*?)\s*\]/ (basically /\[(.*?)\|(.*?)\]/)
   • Replacement (no php): <div class="$1">$2</div>

And make sure 2 weights more than 1.

We should use \ in front of characters [, ], |, because if not, these characters are used by regex for a special purpose. And (.*?) means, "match any character (except newline)". Every character matched within parenthesis can be retrieved by mentioning $n: $1 for first parenthesis, $2 for the second, and so on. $0 is the whole string matched.

I am setting the report as fixed because it got an answer.
