using regex in a dictionary command

[daro]

Hello,

we are trying to create a filter to match for Links where the address mail domain is included.

something like https://example.com/u/id?=daniel@mydomain.com

due to the amount of domains we use I would like to include the domain list with a dictionary, but it seems that the body-dictionary-match does not like regex.
I was currently testing with the follwing string (which obviously does not work), but maybe you guys can correct me there.

body-dictionary-match("(?i)http.+\\@('domain_list'))
match "http" + any character till "@" then include the names in the dictionary

I could use body-contains("(?i)http.+\\@(Test1|Test2|Test3)\\..."), but as I said we use many domains and I want it to be modular if we add a new domain.

I do not know if what I want to accomplish is even possible with that command, but maybe you guys know more.

thanks

Hi Daniel,

You could try using the dictionary directly in the condition such as below.

body-dictionary-match("domain_list", 1)

Then configure the dictionary with the required regex.

http.+\\@Test1

http.+\\@Test2

http.+\\@Test3

.

.

.

etc

The only other way would be to use two conditions, however this would not be accurate matching a single line.

body-contains("(?i)http.+\\@")

AND

body-dictionary-match("domain_list", 1)

Would need testing to see what works best for you.

Thank You!

Hello Libin,

thanks for the update, thats exactly what i want to accomplish.
just a heads up - if you are using regex in a dictionary you do not need the double backslashes.

here is the note from the user guide describing the backslash rule:
Important Note: The backslash is also a special escape character for the parser. As a result, if you want to include backslash in your regular expression, you must use two backslashes — so that after parsing, only one “real” backslash remains, which is then passed to the regular expression system. So, if you wanted to match the example domain above, you would enter ^ik\\.ac\\.uk$.

regards
Daniel
