Delete text portion from a file between two search patterns

[Gerhard Hofmann]

Hello,

I have files to process that look like this:

text before first pattern that should be kept
text before first pattern that should be kept
text before first pattern that should be kept
PATTERN1
text to be thrown away
text to be thrown away
PATTERN2
text after second pattern that should be kept
text after second pattern that should be kept
text after second pattern that should be kept

Desired result after processing:

text before first pattern that should be kept
text before first pattern that should be kept
text before first pattern that should be kept
text after second pattern that should be kept
text after second pattern that should be kept
text after second pattern that should be kept

How could I do this with SFK XE?

TIA

on a single file:

sfk xreplace in.txt "/pattern1[bytes]pattern2[eol]//"

on all .txt files of folder mydir:

sfk xreplace -dir mydir -file .txt -pat "/pattern1[bytes]pattern2[eol]//"
