Hi,

I am using following RegEx to validate email id entered, But somehow it is not working correctly, ie after giving correct email also it not working


data : email type c 30.
data matcher type ref to cl_abap_matcher.
matcher = cl_abap_matcher=>create(
  pattern = `w+(.w+)*@(W+.)+(w{2,4})`
  ignore_case = 'X'
  text = email ).
if matcher->match( ) is initial.
  message 'Wrong Format' type 'I'.
else.
  message 'Format OK' type 'I'.
endif

Note : SCN site restrictions i could not paste the email id here , but i am giving email value as 'ars.ars @ abc.com'. without any spaces

Any Info ?

You might want to try this one, it works ok for me, Found it on the internet.

data : email(30) type c .  "<- set value of mail address
data matcher type ref to cl_abap_matcher.
matcher = cl_abap_matcher=>create(
  pattern = `^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$`
  ignore_case = 'X'
  text = email ).
if matcher->match( ) is initial.
  message 'Wrong Format' type 'I'.
else.
  message 'Format OK' type 'I'.
endif.

I found the problem.

The correct regex will be


pattern = `w+(.w+)*@(w+.)+(w{2,4})`

instead of


pattern = `w+(.w+)*@(W+.)+(w{2,4})`

because of capital W in the regex
