You can try the String#[] method and a regular expression to lo= ok for
the brackets and what's inside. For example:

s =3D "asdl=ADkmlsdmflkm=ADflk elfm lwemf=AD le {asdf=ADsdf sdfds=ADf}= asdf df "
=3D> "asdlkmlsdmflkmflk elfm lwemf le {asdfsdf sdfdsf} asdf df &quo= t;
> s[/{[^}]+}=AD/]
=3D> "{asdfsdf sdfdsf}"

Jesus.
