Betreff: [REBOL] Empty lines Re:
here's my general script for removal of undesired content from text files:
REBOL []
file: read/lines %some-file.txt
result: copy []
what-not: [
empty? trim/all copy line
found? find trim/all copy line "VAHANAVYR"
found? find line "======="
(to-char first line) = (to-char 12)
]
foreach line file [if not any bind what-not 'line [insert tail result line]]
write/lines %result.txt result
just modify what-not block, in your case:
what-not: [
empty? trim/all copy line
]
HTH,
