How to get the part of the string before "|"

Question

In my web scraping exercise, I have come up with a peculiar form of string given by -

st<-c("Samsung Galaxy M21 2021 Edition (Charcoal black , 6GB RAM, 128GB Storage) | FHD+ sAMOLED | 6 Months Free Screen Replacement for Prime")

And I want the part of the string before "|" i.e., I want the output as:

"Samsung Galaxy M21 2021 Edition (Charcoal black , 6GB RAM, 128GB Storage)"

I am trying as s <- st %>% str_replace("|.*","") but didn't get any improvement over "st"(defined above)

What's the website? There may be a better way to get the string you are after. How are you getting the result you show above? — QHarr, Sep 26 '21 at 22:57
Actually, this is one of the names of the phone I found when I search "Realme Mobile Phones" on amazon. in. There only a few names are in that form. For more details you can visit: https://www.amazon.in/s?k=Realme+Mobile+Phones&ref=nb_sb_noss_2 — Debojit Roy, Sep 26 '21 at 23:13

You can try -

st<-c("Samsung Galaxy M21 2021 Edition (Charcoal black , 6GB RAM, 128GB Storage) | FHD+ sAMOLED | 6 Months Free Screen Replacement for Prime")

sub('\\s*\\|.*', '', st)
#[1] "Samsung Galaxy M21 2021 Edition (Charcoal black , 6GB RAM, 128GB Storage)"
