How to use regexp to grab elements of a tcl string

I have extracted some data from a tabular column using "lsearch" and now have a TCL variable like this

{     1      no8  MASTER  (UP-DOWN)  ABCD     1456  /clown        F    right_left_123  /local/opt/data  WXYZ    (M5,N6)          }

How can I now use "regexp" to grab each of these values into separate variables? I guess I will have to filter by space, but the blank space between these values are variable.Also, I am a "regexp" newbie.

I tried using "lindex" but looks like the entire element is in index 0. Please let me know what is the easiest way.

lsearch has probably returned a list containing this 1 element. If you want to now get the elements inside this element, use a second index, to go 1 level deeper:

# suppose the list in in the variable $l
puts [lindex $l 0 0]
# => 1
puts [lindex $l 0 1]
# => no8
