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"

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)

regards
Lilantha
