Question

I’m parsing an external feed which contains location and date inside post title which I want to get rid of, so:

This happened on Date in Location

I need to find on (space on space) and remove everything till the end of the line, same for in(space in space).

I googled a bit, but regex is really unfathomable for me so I’d appreciate any help.

Thanks!

Answer 1

Well, a literal “on” does match exactly. Then tell the regex engine to match everything after: “.*“. (Note, that the . doesn’t match newlines, so it works as needed.)

In the case of “in” you need an alternative, which is marked by parentheses () and the vertical bar |: “(on|in)“. You could also make that a bit tighter with character classes []: “[oi]n“.

With that we arrive at this regex:

/ [oi]n .*/
