Subject: Regexp to match strings that _don't_ being with a string

I would like to write a regexp that will match a string that does NOT 
start with a specified set of characters.

For example,

Given:

xyz123
asldfhsl
xyk2345

and assume that I want to see only strings that don't start with "xyz" 
(so in this case, the last 2 in the list).

I tried /^[^(xyz)]/ but I don't trust it.  I don't think the grouping 
will take inside the character class.

Do I need a negative lookahead assertion?

Thanks,
Wes
