If the part you left out can contain matching pairs of braces:

foo {
   bar {
   };
};
[download]

then I encourage you to try Parse::RecDescent. If the part you left out can also contain braces that are quoted or escaped in some way:

foo {
    bar "No closing } found!"
};
[download]

then I strongly encourage you to try Parse::RecDescent.
