When I run the program: 
{ 1a { 1.1a } 1b { 1.2a    } 1c { 1.3a 1.3b }  }
        { 1.1a }
        { 1.2a    }
        { 1.3a 1.3b }
{ 2a { 2.1a}  }
        { 2.1a}
Now you know exactly what I am trying to do... When I change my string to.. 
$_ = q!0a { 1a { 1.1a } 1b { 1.2a    } 1c { 1.3a { 1.3.1a } 1.3b }  } 
+0b { 2a { 2.1a}  } 0c!;

I get the output 
{ 1a { 1.1a } 1b { 1.2a    } 1c { 1.3a { 1.3.1a } 1.3b }  }
        { 1.1a }
        { 1.2a    }
        { 1.3.1a }
{ 2a { 2.1a}  }
        { 2.1a}
What I want is 
{ 1a { 1.1a } 1b { 1.2a    } 1c { 1.3a 1.3b }  }
        { 1.1a }
        { 1.2a    }
        { 1.3a  { 1.3.1a } 1.3b }
                {1.3.1.a}
{ 2a { 2.1a}  }
        { 2.1a}
Thus nested braces upto any level should be taken care..
Any pointers, solutions, hints are appeciated..
Thanks
