[Pyparsing] How to get to a specific block of text I need

[Malahal N. <ma...@gm...>]

I am trying to implement a config editor for a project. The config
syntax is very simple. It consists of "key value" pairs in blocks.
Blocks may have sub-blocks (only one level at this time).

An example:

export {
     path = path1;
     key2 = value2;
     client {
           clientid = value3;
           key4 = value4;
    }
    client {
           clientid = value6;
    }
}

The "export" is uniquely identified by a specific "path"  value.  Same
is the case with "client" block inside the "export" block which is
identified by the "clientid" value.

Given an export path, I would like to fetch the corresponding export
block. Of course, I can easily match all exports and search each such
block for a matching "path". Similarly, for a given path and clientid,
I would like to get the corresponding "client" block quickly as there
may be 1000's of these sub-blocks in the export block.
