You could do it using the following regex (using capturing group and positive lookahead) :

input        >>  2017 - Alpha Romeo United kingdom : New vehicle (by abc)
regex search >>  (?=:):(.*)
replace with >>  " "
output       >>  2017 - Alpha Romeo United kingdom

see demo / explanation

smarty

{
    assign
    var = "articleTitle"
    value = "2017 - Alpha Romeo United kingdom : New vehicle (by abc)"
} {
    $articleTitle | regex_replace: "/(?=:):(.*)/": " "
}

Thanks siam, for some reason its not working in smarty. but the below expression removing \n. {assign var="articleTitle" value="Infertility unlikely to\nbe passed on, experts say."} {$articleTitle|regex_replace:"/[\r\t\n]/":" "}I want something to work in smarty. – Developer Feb 23 '17 at 11:26
@Developer what you actually trying to replace? the value doesn't even match with the string that you provided in the question – m87 Feb 23 '17 at 11:34
I want to print everything before colon, no function seems to work in smarty. except the above one I mentioned in comment. my final output for the string i provided should be "2017 - Alpha Romeo United kingdom" using regex_replace function – Developer Feb 23 '17 at 11:38
@Developer is native php is an option for you? – m87 Feb 23 '17 at 11:44
its not accepting php, otherwise i would have used simple explode. :( can you use the example above mentioned in my comment to get the output from string – Developer Feb 23 '17 at 11:46
@Developer check updated answer – m87 Feb 23 '17 at 11:56
Great siam. working like a charm. thanks a ton. you saved my day :) – Developer Feb 23 '17 at 12:02
