Problem with \w

Ruby

Hi there,

please help me with my problem.

you want to create from “?X is parent of ?Y” ===>> “(\w+) is parent of
(\w+)”

I was trying something like:

“?X is parent of ?Y”.gsub(/?[A-Z]/) { “(\\w+)” }
“?X is parent of ?Y”.gsub(/?[A-Z]/) { “(\\w+)” }
“?X is parent of ?Y”.gsub(/?[A-Z]/) { “(\w+)” }
“?X is parent of ?Y”.gsub(/?[A-Z]/) { “(\w+)” }

but nothing,

thx in forward,

p.s.

but nothing,

This works:

1.9.2p290 :001 > s = “?X is parent of ?Y”
=> “?X is parent of ?Y”
1.9.2p290 :002 > s.gsub(/?[A-Z]+/, “(\w+)”)
=> “(\w+) is parent of (\w+)”
1.9.2p290 :003 > puts s.gsub(/?\w+/, “(\w+)”)
(\w+) is parent of (\w+)
=> nil

Take note that what IRB returns is the inspect of the string, so you
see double backslashes. If you print it, you’ll see the unescaped
backslash character.
