StringSplit

StringSplit["string"]
splits into a list of substrings separated by whitespace.

StringSplit["string", patt]
splits into substrings separated by delimiters matching the string expression patt.

StringSplit["string", {p₁, p₂, ...}]
splits at any of the .

StringSplit["string", patt->val]
inserts val at the position of each delimiter.

StringSplit["string", {p₁->v₁, ...}]
inserts at the position of each delimiter .

StringSplit["string", patt, n]
splits into at most n substrings.

StringSplit[{s₁, s₂, ...}, p]
gives the list of results for each of the .

Details and Options Details and Options

StringSplit[s] does not return the whitespace characters that delimit the substrings it returns.
Whitespace includes any number of spaces, tabs, and newlines.
The string expression patt can contain any of the objects specified in the notes for StringExpression.
StringSplit[s] is equivalent to StringSplit[s, Whitespace].
If s contains two adjacent delimiters, StringSplit considers there to be a zero-length substring between them.
StringSplit[s, patt] by default gives the list of substrings of s that occur between delimiters defined by patt; it does not include the delimiters themselves.
StringSplit[s, patt->val] includes val at the position of each delimiter.
StringSplit[s, patt:>val] evaluates val only when the pattern is found.
StringSplit["string", {p₁->v₁, ..., p_a, ...}] includes at the position of delimiters matching , but omits delimiters matching .
By default, StringSplit[s, patt] drops zero-length substrings associated with delimiters that appear at the beginning or end of s.
StringSplit[s, patt, All] returns all substrings, including zero-length ones at the beginning or end.
Setting the option IgnoreCase->True makes StringSplit treat lowercase and uppercase letters as equivalent.
StringSplit["string", RegularExpression["regex"]] splits at delimiters matching the specified regular expression.
