How can be done recursive parsing with CL-PPCRE?
For example infix arithmetic expressions with parentheses..

Depends on your specific problem.  Generally, recursive parsing can't
be done with regular expressions alone - check out text books like the
"Dragon Book" for a mathematical proof.

  <http://catb.org/~esr/jargon/html/D/Dragon-Book.html>

For approaches how regular expressions (and CL-PPCRE in particular)
can help when building parsers see the mailing list archives and again
consult a good CS text book.

Cheers,
Edi.

No.  This won't be easy because of all the backtracking involved, and
I have no plans to add that.

There's a modified version of CL-PPCRE which handles arbitrary
sequences but I guess this won't help you very much:
