Subject: Short question on regex in Ruby

Hi,

I have a little problem with a regex in Ruby:

I have twos strings:

string1 = "He is the 20th."
string2 = "25th"

I wrote this to "extract" the place (20 or 25 respectively):

place1 = string1.gsub(/.*(\d+)th.*/,'\1')
place2 = string2.gsub(/.*(\d+)th.*/,'\1')
pp place1
pp place1

=> "0"
=> "5"

Of course, I would like to get all the digits before "th". Why is only
the last one captured?

If anyone could please explain this, and help me come up with a regex
that captures 20 and 25, respectively, this would be greatly
appreciated.

Cheers, Chris
