    I would suggest looking at the tcl scan command to get started. If I get a little time, I'll try to give you an example you can use, but wanted to at least suggest a starting point. (Otherwise regex may work, but it's much less efficient)

    Here's an example that based on the 

    scan
    command that worked in my testing

    set isFound [scan $a {%[^&]&_%d%s"} x c x]
 x == garbage. no need to do anything with it
 c == the ID string
