Syntax

[the] trNthField of ( string , delimiter , index )

trNthField ( string , delimiter , index )

String yields any string. Delimiter yields a string describing a set of characters. Index yields an integer.

Description

The trNthField function returns a chunk of the specified string delimited by any of the characters in the specified delimiter, not including any trailing empty chunks. Index starts at 1.

Delimiter describes a set of characters, not a string. A range of characters can be specified by putting a hyphen between two characters; to match a literal hyphen, put a hyphen at the beginning or end. For example, the following pattern matches all numbers and basic Latin letters, as well as hyphens: A-Za-z0-9-

If index is less than 1 or greater than trCountFields(string, delimiter), empty is returned.
