windows - Split string with string as delimiter

Question

I'm trying to split a string in a batch file using a string (rather than a character) as the delimiter.

The string has the format:

string1 by string2.txt

The delimiter is by (yes, space, the word 'by', followed by space). The output I want is:

string1

string2

So, basically, split the string into 2 parts by the delimiter by and remove the suffix from the second string. How can I do this?

Answer 1

Try this:

for /F "tokens=1,3 delims=. " %%a in ("%string%") do (
   echo %%a
   echo %%b
)

that is, take the first and third tokens delimited by space or point...
