segment - Splitting a string into segments

The segment function splits the string string into individual, separator-separated segments and returns the segment at the specified index.

segment(string, separator[, index])

Argument	Description
`string`	The string to be split into segments.
`separator`	The delimiter that separates the segments within the string.
`index` (optional)	Specifies the position of the segment to be returned. Counting starts at 0, where `index = 0` returns the first segment.

The function returns the segment at the specified index as text.

Counting starts at 0, not at 1.
If the index is outside the available segments, the function returns an empty value.
