Help with regexmatch

[-Elaphe-]

Could anyone please tell me the regexmatch to remove part of the filename of a series of files. It should remove everything from the first "_" to the second "_" found, both "_" included. Thank you very much.

Code: Select all

#Requires AutoHotkey v1.1.36.02
MsgBox % RegExReplace("aaaaa_bbbb_CCCC", "_[^_]+_") ; aaaaaCCCC

Thank you, but in this case also other "_" after that are also removed:

Code: Select all

MsgBox % RegExReplace("aaaaa_bbbb_CCCC_dddd_eeee.mp4", "_[^_]+_")

result: aaaaCCCCeeee.mp4
expected: aaaaCCCC_dddd_eeee.mp4

Code: Select all

MsgBox % RegExReplace("aaaaa_bbbb_CCCC_dddd_eeee.mp4", "_[^_]+_", , , 1) ; aaaaaCCCC_dddd_eeee.mp4

Thank you very much. It works great.

Finally (and sorry to bother you again), how would it be to have this transformation?

aaaaa_bbbb_CCCC_dddd_eeee.mp4 --> aaaaa_CCCC_dddd_eeee.mp4

Code: Select all

MsgBox % RegExReplace("aaaaa_bbbb_CCCC_dddd_eeee.mp4", "_[^_]+(?=_)", , , 1) ; aaaaa_CCCC_dddd_eeee.mp4
