Function: split()
Splits a string where a separator occurs, returning a list of substrings.
Syntax
split(string, separator)
| Argument | Type | Description |
|---|---|---|
| string | String | String to be split |
| separator | Regular Expression | Regular expression representing the breakpoints in string where the splits should occur |
Note that the separator is expressed as a regular expression. This means that you can use any pattern that can be expressed as a regular expression as a separator. But it also means that you must escape any special characters of regular expressions if you are using these as plain text (e.g. you must use "\\|" to use | as a separator). See examples below.
Examples
split("one,two,three",",")returns
["one","two","three"]
split("one::two::three","::")returns
["one","two","three"]
split("one::two::","::")returns
["one","two",""]
split("::::","::")returns
["","",""]
split("field1|field2|field3","\\|")
returns
["field1","field2","field3"]
This expression will split the string at any single digit between 0 and 9:
split("some text1more text3final text","[0-9]")returns
["some text","more text","final text"]
