GetBetween

GetBetween is a common programming concept or function found in various programming languages and libraries. Its primary purpose is to extract a substring that lies between two specified delimiter strings. For instance, if you have a string like "data[important_value]more_data", a GetBetween function could be used to retrieve "important_value" by specifying "[" as the starting delimiter and "]" as the ending delimiter.

The behavior of GetBetween can vary slightly depending on the implementation. Some versions might only find the first occurrence of the delimiters, while others might find all occurrences. There can also be differences in how leading or trailing whitespace around the extracted substring is handled. Error handling is another important aspect; what happens if the starting or ending delimiter is not found, or if the ending delimiter appears before the starting delimiter? Common approaches include returning an empty string, null, or raising an error.

GetBetween is a useful tool for parsing text, extracting information from structured strings, or manipulating data where specific values are enclosed by known markers. It simplifies the process of isolating desired segments of text without needing to write complex regular expressions or manual string manipulation for every case. Its availability in libraries often makes it a convenient and readable solution for developers.
