ExtractWord
Extract the N-th word out of a string.
Declaration
Source position: strutils.pp line 200
function ExtractWord(N: Integer; const S: string;
const WordDelims: TSysCharSet) : string;
Description
ExtractWord extracts the N-th word from the string S. The set of characters in WordDelims are used to mark word boundaries. A word is defined as any non-empty sequence of characters which are not present in WordDelims: if a character is not in WordDelims, it is considered as part of a word. If an N-th word cannot be found, an empty string is returned.
Unlike ExtractDelimited , an empty string is not a valid return value, i.e. is not a word. If an empty string is returned, the index N was out of range.
The predefined constant StdWordDelims can be used for the WordDelims argument.
Errors
None.
