Imam string
"win98 i win 98 i windows"

treba mi regexp koji ce da nadje 'win' ako u nastavku nije 'dows'
znaci, da nadje 'win98' i 'win 98', ali ne i 'windows'

jedino sto sam uspeo je
Win[^d]

Mogu da negiram jedno slovo (d), ali nikako da uspem da negiram string ("dows")

Neko resenje?

p.s. nemojte samo da mi dajete perl regexp, posto bih voleo iskljucivo regexp...

evo ti dole perlregexp

najbolje da mi poshaljesh skript pa cu da ti napishem kod

"(?=pattern)"
A zero-width positive look-ahead assertion. For example, "/\w+(?=\t)/" matches a word followed by a
tab, without including the tab in $&.

"(?!pattern)"
A zero-width negative look-ahead assertion. For example "/foo(?!bar)/" matches any occurrence of "foo"
that isn't followed by "bar". Note however that look-ahead and look-behind are NOT the same thing.
You cannot use this for look-behind.

If you are looking for a "bar" that isn't preceded by a "foo", "/(?!foo)bar/" will not do what you
want. That's because the "(?!foo)" is just saying that the next thing cannot be "foo"--and it's not,
it's a "bar", so "foobar" will match. You would have to do something like "/(?!foo)...bar/" for that.
We say "like" because there's the case of your "bar" not having three characters before it. You could
cover that this way: "/(??!foo)...|^.{0,2})bar/". Sometimes it's still easier just to say:

if (/bar/ && $` !~ /foo$/)

pa kakav kod pobogu, nema tu koda, to je jedna linija, treba samo regexp da se formulise.

<?
$agent=eregi_replace ("win([^d])", "windows\\1", $agent);
?>

treba mi regexp koji ce da nadje 'win' ako u nastavku nije 'dows'
znaci, da nadje 'win98' i 'win 98', ali ne i 'windows'

i po mogucstvu da ne bude perl regexp

evo ovako bez provere

if (!preg_match('/windows/', $agent)):
$agent=eregi_replace ("win\s?(\d+)", "windows\\1", $agent);
endif;

btw ako ti ne bude radi ereg_replace samo uradi verziju sa preg_replace

\s? matchuje jedan ili nijedan space

a u zagradi hvatash jedan ili vishe brojeva
