Smarty regex_replace: how to find one string after match

Question

We are trying to use regex_replace in tpl file:

{$item->order->order->notes_priv|regex_replace:"/.+?(?=MATCH)/":""}

But this leaves all strings after "MATCH" not the only first one after "MATCH".

We have this text and would like to input only one string after word MATCH:

foo bar foo bar MATCH 12 foo bar
foo bar foo bar MATCH 24,00 foo bar

How we can make input?

12
24,00

We tried many solutions but without success.

You can use

regex_replace:'/.*MATCH\s+(\S+).*/':'$1'

See the regex demo.

The main idea is to match the whole string, capture just a part and replace with a backreference to the captured group value.

Details:

• .* - any zero or more chars other than line break chars as many as possible
• MATCH - a literal string
• \s+ - one or more whitespaces
• (\S+) - Group 1 ($1 in the replacement pattern): any one or more non-whitespace chars
• .* - any zero or more chars other than line break chars as many as possible.
