[Boost-users] [xpressive] Pattern problems (newbie)

Hi,

I'try to build a regex for an ibis file, the line I'm interested looks like:

[IBIS Ver]      3.2   | Used for template variations"

where '|' is an optional comment identifier with the (therefore 
optional) comments follows. I'm interested in the version self: "3.2" to 
   create a parser using a factory.

Using egrep '^\[IBIS Ver]' success.

 From docs I tested the dynamic regex

$ perl -p -e '(\\w+) (\\w+)!' "Hello World"

which fails  (syntax error at -e line 1, near "+) ")

The regex are perl syntax, isn't? What is the regex for my IBIS Ver 
identifier?

Thanks,
Olaf
