string help (using a specific part of a string?)

[br00]

what it is, i have a string that always contains the word 'Size', i want to use only that which comes befor that word and forget the rest... have done some searching but to no avail

ie:
blah blah blah etc. Size
i want to use just the 'blah blah blah etc' bit (which is different every time)

so... how to cut the string at 'Size'??

[deadite66]

this works for me, might be a better way though.

Code: Select all

set sline "blah blah blah etc. Size"
set oline [string range $sline 0 [expr [string first "Size" $sline] - 1]]
puts $oline

u could use regexp:

Code: Select all

regsub -all -- $sline "Size.*" sline ""

but be away that in both my solution and deadite66's , if the bla bla contains the word Size it will be removed too.

advise: there is also a 'string last'
