string manipulation

[sl1200mk2]

hi all

how to deal with that
here's the string
step0mem0time-in0time-out0delay-in0delay-out0wait0nullstep1mem1time-in2time-out2delay-in0delay-out0wait0nullstep2mem2time-in2time-out2delay-in0delay-out0wait1null

i would like to get
step 0 mem 0 time-in 0 time-out 0 delay-in 0 delay-out 0 wait 0
step 1 mem 1 time-in......

i've put the "null" char to prmit a \n
what i don't know to do is spacing word of num

any helps are welcome, as usual....
best regards

nico

I think a 2-step process using regsub:
First, we'll call the string you're parsing, "instr":
set instr step0mem0time-in0time-out0delay-in0delay-out0wait0nullstep1mem1time-in2time-out2delay-in0delay-out0wait0nullstep2mem2time-in2time-out2delay-in0delay
-out0wait1null

Next, we'll use regsub to put a space every time a letter is followed by a digit:
regsub -all {(\w)(\d)} $instr "\\1 \\2" outstr
and put the output in "outstr"

Next, we put a space every time a digit is followed by a letter:
regsub -all {(\d)(\w)} $outstr "\\1 \\2" outstr
and the output is still in "outstr"

the result is:
step 0 mem 0 time-in 0 time-out 0 delay-in 0 delay-out 0 wait 0 nullstep 1 mem 1 time-in 2 time-out 2 delay-in 0 delay-out 0 wait 0 nullstep 2 mem 2 time-in 2 time-out 2 delay-in 0 delay-out 0 wait 1 null

bong, you're at the top

let's organize a "Summer Tcl Beach Festival......."

[sl1200mk2]

still many thanks

what we have done:
parse an xml file in a text widget
make readable by anyone
save it back in xml format
and parse it again.....

well done

one more thing:
i've tried with step 200 for example....

it display
step 2 0 0
and not
step 200

it doesn't really matter because my xml formatter understand 200
but....

do you have an idea?

Well, I'm not really very good with RE_syntax. I think "\w" is alphanumeric, not just alpha, which would explain the behavior. Maybe if you substitute "[a-zA-z]" for "\\w" it would work better?

perhaps you're not really very good, but you're very good with RE_

it was the solution...

well done
