 Example:
 
-```uce
-String html = regex_replace(

 Replacement strings use PCRE2 substitution syntax, including numbered capture references such as `$1` and named references such as `${name}`.
 
 For simple literal search-and-replace, use `replace()`. Use `regex_replace()` when the match condition needs a pattern, captures, character classes, anchors, or flags.
 
 Invalid patterns, invalid flags, or invalid substitution syntax raise a request-visible runtime error.
