given a string:
str := '2015-09-14 14:46:50 downloadrate (813 KB/s)'
if i want to get the first word ( worddelim is space ) i use:
Result := ExtractWord(1 ,str,[' ']);
Result is '2015-09-14'
That's clear :-))
If i want to extract '(813 KB/s)', i have to extract the SECOND word!!
Result := ExtractWord(2 ,str,['( ', ')']);
Result is '813 KB/s'
Why do i have to extract the SECOND word? The word inside () occurs just
Delphi 5 delivers the same Result so i'm sure i misunderstand something?!!
lhelp tells me:
> 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.
Explanations are welcome.
