Hi,

I am doing a validation for valid mail-ids thru REGEX . Here is the code for this . but it is not giving any results back.


report  zars.

data: regex   type ref to cl_abap_regex,
      matcher type ref to cl_abap_matcher,
      match   type c length 1.

create object regex exporting pattern = ' [A-Z0-9._%+-]+@[A-Z0-9.-]+.[A-Z]{2,4} '
                              ignore_case = ''.

matcher = regex->create_matcher( text = '"abc^abc.ca"' ).

match = matcher->match( ).

write match.

Any Info?

Did you try using an alternative pattern like:

[a-z0-9!#$%&'/=?^_`{|}~-](?:\.[a-z0-9!#$%&'/=?^_`{|}~-])@(?:[a-z0-9](?:[a-z0-9-][a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?

Hope it helps,

this looks better!

"[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?"

Thanks for your reply. Your reply give me a hint to solve this issue

I tried in this way


[w]+@[w]+.[w]{2,3}

Here is the details:->

—The w represents any word-letter (A-Z,a-z and 0-9). This is then bracketed so that the plus modifier can be used to specify one or more. Therefore, tells the parser to match on one or more word-letters.

@—Tells the parser to look for the at-sign—@—character

+—As before, tells the parser to match on one or more word-letters

.—Match on the period character

{2,3}—Once again, the pattern specifies a search for word-letters with the difference here being that the {x,y} modifier tells the parser to search for a specific number of word-letters—two or three, in this case.
