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

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)

CodePudding user response：

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)"
