Careful, the * is greedy, so it will consume as many characters as it= can:

> s =3D "adf {firs=ADt one} seomt=ADhing {seco=ADnd one} dfdsf=AD&q= uot;
=3D> "adf {first one} seomthing {second one} dfdsf"
> s[/({.*})/=AD]
=3D> "{first one} seomthing {second one}"

That's why I used the negative character set, to match everything that<= br> is not a closed bracket. You can also use the ? modifier:

> s[/({.*?})=AD/]
=3D> "{first one}"

Jesus.
