Special RegExp

[Zarkan]

Hi all,
I've got a question for you, Regular Expression Masters

I'm not very experienced in that, but I've made many attempts and I
couldn't get the right regExp yet..

Basically, I need a regular expression able to find a certain string
(say, "abc") which is NOT followed by an HTML tag (that is, which is
not followed by "<").

I've tried with this:
/abc[^<]/

...But this actually does something different:
it finds "abc" when *followed by a character* which is different from
"<".

But I want to find the string when it's followed:
a) either by NOTHING
b) or by a character different from "<"

Then, I tried this (in order to find "abc" + no character, OR 1
character different from "<"):
/abc[^<]{0,1}/

...But this expression doesn't work either (that is, it matches the
string also when it's followed by "<")!

I've tried many other ways, but with no success!!
How shall I do??

Many thanks,
Zark

var a = 'abc';
var b = 'abc<';
var c = 'abcd';
var re = /abc([^<]|$)/;
alert(
a + ': ' + re.test(a) + '\n' +
b + ': ' + re.test(b) + '\n' +
c + ': ' + re.test(c)
);

Thankssss!
That works fine!!
