Hi

I have a string which would be something like below :

set myStr "{8} {Security Configuration} {null} {}} {{9}"

I would to retrieve what is present inside the flower braces after
Security Configuration which is "null" in this case. Can i do this with
a regular expression ?

Thanks
Arun

set result [ lindex [ string map { \{\{ \{ \}\} \} } $myStr ] 2 ]

Bad example. You should never use lindex or any other list command on strings. The above may work for the above very specific case, but it can break in so many ways for so many forms of real world data.
