Splitting a string

Posted by acidburn123 (acidburn123), 27 April 2008
Hey guys, I've seemed to have hit a brick wall. I've been trawling the internet for the last half hour and can't seem to figure out how to solve such a problem.

Basically I've got a string which contains a series of characters and I'm wanting to append a newline char when a certain character occurs.

I've got this so far:
 set b "Hello this//rocks my//world"
   set c [ split $b '//']
   puts $c

I figured if I split it, i could somehow access the elements like an array and append to each element, but this ain't been successful. Any pointers?

Use a regular expression - it's a "one liner"

set stuff "The piece of cake//The Crumb of Currant//The Almond"
set newstuff [regsub -all // $stuff "\n" ]
puts $newstuff

earth-wind-and-fire:~ grahamellis$ tclsh tc
The piece of cake
The Crumb of Currant
The Almond
