Hi, I am looking for a Java regexp lib with support for recursion, like: "<a+(?0)>" JDK does not support it, ORO does neither. Anyone knows about such? Thanks, Ondra Edit: See http://www.php.net/manual/en/regexp.reference.recursive.php And I need it for this expression: (?:mUi)^/--++ *+(.*)(?: *(?<= |^)\\.((?:\\([^)\\n]+\\)|\\[[...

PCRE has a feature called recursive pattern, which can be used to match nested subgroups. For example, consider the "grammar" Q -> \w | '[' A ';' Q* ','? Q* ']' | '<' A '>' A -> (Q | ',')* // to match ^A$. It can be done in PCRE with the pattern ^((?:,|(\w|\[(?1);(?2)*,?(?2)*\]|<(?1)>))*)$ (Example test case: http://www.ideone.com/...

After reading polygenelubricants's series of articles on advanced regular expressions techniques (particularly How does this Java regex detect palindromes?), I decided to attempt to create my own PCRE regex to parse a palindrome, using recursion (in PHP). What I came up with was: ^(([a-z])(?1)\2|[a-z]?)$ My understanding of this expr...

Hi all, I'm pretty clueless when it comes to PHP and regex but I'm trying to fix a broken plugin for my forum.
