Subject: Multiple matching with ()*

Hi there!
I'm Alessandro from Italy and I started using ruby some days ago,
so... Hello, Community! :)

Well, I was trying to match a pattern multiple times. I tried both
with normal match() and scan(), but i can't get the desired result.

The subject string is something like:
"1a2bend" or "beg1a2b3c4dend"
more generally, it should match /^beg(\d\w)*end$/ : always a begin and
ending pattern, and a unspecified number of central pattern.
The problem is that the central pattern must be extracted for every
time it's encountered.
For example, trying with
"x1A2B3C4Dz".scan /^(x)(\d\w)*(z)$/
returns
[["x", "4D", "z"]]
while i need something like
[["x", "1A", "2B", "3C", "4D", "z"]]

Why does ()* match just the last one? How can i get all the ()* that it matches?

Probabily i'm doing something wrong, but can't understand where :\

Thanks!
