Hi,
I'm using the following regular expression: 'foob.*r'
Calling MatchString() against each of the items in the stringlist, I
expected it to match 3 items. Instead it only matches the first item
and fails all the rest. Why???
--------------[ source code ]-------------------
sl := TStringList.Create;
sl.Add('1st foobr Item');
sl.Add('2nd Item');
sl.Add('3rd Item');
sl.Add('4th foobaoeuaor Item');
sl.Add('5th foobar Item');
r := TRegexEngine.Create('foob.*r');
x := 0;
y := 0;
for i := 0 to sl.Count-1 do
begin
if r.MatchString(sl.Strings[i], x, y) then
writeln('match')
else
writeln('failed');
end;
r.Free;
sl.Free;
--------------[ output ]-------------------
match
failed
failed
failed
failed
Based on the syntax documentation from TRegEx (which I believe 'regex'
unit closely represents) and looking at the syntax comments inside the
regex.pp unit, it should match the following...
Examples:
foob.*r matchs strings like 'foobar', 'foobalkjdflkj9r' and 'foobr'
http://regexpstudio.com/TRegExpr/Help/regexp_syntax.html
About halfway down the page...
even trying a filter as follows, match NO items in the stringlist???
r := TRegexEngine.Create('th');
I expected it to match items '4th' and '5th', but it didn't.
Regards,
