RE: forward look ahead assertion

Does this pattern come in a single line ?
 Then you can use ^abc\.xyz$ , this will match "abc.xyz" but not
"pqrabc.xyz123"
 Or abc\.xyz$ this will match "abc.xyz" "pqrabc.xyz" but not
"pqrabc.xyz123"

Subject: forward look ahead assertion


Hi 

Could you tell me whether the regexp supports forward look ahead assertion
or not? If not how could we
managed to test a patter like:

abc.xyz

which I need to match exactly abc.xyz but not

abc.xyza
abc.xyzab etc...

I.e. xyz should not follow any other characters. 

In Perl we could achieve this kind of matching using pattern like:
(?:abc.xyz)(?!\w)
