words2 : string -> string -> string list
STRUCTURE
Lib
SYNOPSIS
Splits a string into a list of substrings, breaking at occurrences of a specified character.
DESCRIPTION
words2 char s splits the string s into a list of substrings. Splitting occurs at each occurrence of a sequence of the character char. The char characters do not appear in the list of substrings. Leading and trailing occurrences of char are also thrown away. If char is not a single-character string (its length is not 1), then s will not be split and so the result will be the list [s].
FAILURE
Never fails.
EXAMPLE
- words2  "/"  "/the/cat//sat/on//the/mat/";
> val it = ["the", "cat", "sat", "on", "the", "mat"] : string list

- words2  "//"  "/the/cat//sat/on//the/mat/";
> val it = ["/the/cat//sat/on//the/mat/"] : string list

COMMENTS
The SML Library functions String.tokens and String.fields offer similar functionality.
