Help with GREP code to find duplicate text

Hello:

I have a issue with movies times (something Google must have added to their codes) because when I copy/paste movie times from Google to format for newspapers, it added a line that read: Showtimes for (then the name of the movie) and there is a duplicate of the title next to this line.

If you search for movie times in your area and copy/paste into InDesign, you'll see what I mean.

I have a script that formats the titles and times, but now it still has the "Showtimes for....stuff in the text.

And I'm trying, unsuccessfully, to delete to "Showtimes for and one of the duplicate titles.

So far, I have tried this:

(\b\w+)( \1)+\b

It will find duplicates, but only one-word duplicates.

I've got this too.  But it finds everything in between and I can't figure out how to isolate the text that I want to delete.

(?<=Showtimes for)(.+?)(?=\d\d+)

I need to search for entire titles that have different words and word counts.

Here is a sample:

Showtimes for A Dog’s Way Home A Dog’s Way Home 12:35pm 5:00pm 7:45pm Showtimes for Mary Poppins Returns Mary Poppins Returns 12:35pm 3:35pm 6:45pm Showtimes for Bumblebee Bumblebee 1:15pm 4:20pm 7:20pm Showtimes for Spider-Man: Into the Spider-Verse Spider-Man: Into the Spider-Verse 12:40pm 4:15pm 7:10pm

Thanks for any help.

Sorry for the long text.

Larry
