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?

You can use the split() method of String class from JDK to split a String based on a delimiter e.g. splitting a comma-separated String on a comma, breaking a pipe-delimited String on a pipe, or splitting a pipe-delimited String on a pipe.
In Java, delimiters are the characters that split (separate) the string into tokens. Java allows us to define any characters as a delimiter. There are many string split methods provides by Java that uses whitespace character as a delimiter. The whitespace delimiter is the default delimiter in Java.
Use the Split method when the substrings you want are separated by a known delimiting character (or characters). Regular expressions are useful when the string conforms to a fixed pattern. Use the IndexOf and Substring methods in conjunction when you don't want to extract all of the substrings in a string.
Split(char[]) Method This method is used to splits a string into substrings that are based on the characters in an array. Syntax: public String[] Split(char[] separator); Here, separator is a character array that delimits the substrings in this string, an empty array that contains no delimiters, or null.
I recently discovered an interesting trick that allows to "Split String With String As Delimiter", so I couldn't resist the temptation to post it here as a new answer. Note that "obviously the question wasn't accurate. Firstly, both string1 and string2 can contain spaces. Secondly, both string1 and string2 can contain ampersands ('&')". This method correctly works with the new specifications (posted as a comment below Stephan's answer).
@echo off
setlocal
set "str=string1&with spaces by string2&with spaces.txt"
set "string1=%str: by =" & set "string2=%"
set "string2=%string2:.txt=%"
echo "%string1%"
echo "%string2%"
For further details on the split method, see this post.
