regex_replace

A regular expression search and replace on a variable. Use the RegExp from JavaScript.

Only modifiers (flags) 'i' and 'm' are supported in this version.

Backslashes should be escaped e.g. \s

    {$foo = bar}
    {$foo|regex_replace:'/b/':'z'}   //zar

---

Note:- Although jSmart supplies this regex convenience modifier, it is usually better to apply regular expressions in JavaScript, either via custom functions or modifiers. Regular expressions are considered application code and are not part of presentation logic.
