Hi,

you can use named recursion for that. Search for (DEFINE) in http://perldoc.perl.org/perlre.html However, you should remember that recursion is atomic in PCRE.

Or if you use a script language you can simply assign a string variable and concatenate it:

word = "[\p{Latin}\-]+"
regex="(" + word + "," + word + ")+"

Just be creative ;)

Zoltan

I find myself the last few days writing pcre regexp like :>

"^([\\p{Latin}\\-]+)\\s(?i:v|var)(?::|\\.|\\s)\\s?([\\p{Latin}\\-]+)\\s(?i:f|forme)(?::|\\.|\\s)\\s?([\\p{Latin}\\-]+)$">

the double backslash beeing a thing of the String module of the host language, ocaml here.>

Is there any plan to add a feature enabling the user to name a part of a regexp like :>

[\p{Latin}\-]+>

(which is just a souped up \w+)>

and reuse it later, would allow more readable writing of long regexp.>

would be a really nice feature !>
