Source position: strutils.pp line 200
function ExtractWord( |
N: Integer; |
const S: string; |
const WordDelims: TSysCharSet |
):string; |
N |
|
Which word to extract. |
S |
|
String to extract the word from. |
WordDelims |
|
Characters to use as word delimiters |
The N-th word, or empty if N is out of range.
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.
