# xurls
[![GoDoc](https://godoc.org/mvdan.cc/xurls?status.svg)](https://godoc.org/mvdan.cc/xurls)
Extract urls from text using regular expressions. Requires Go 1.12 or later.
```go
import "mvdan.cc/xurls/v2"
func main() {
rxRelaxed := xurls.Relaxed()
rxRelaxed.FindString("Do gophers live in golang.org?") // "golang.org"
rxRelaxed.FindString("This string does not have a URL") // ""
rxStrict := xurls.Strict()
rxStrict.FindAllString("must have scheme: http://foo.com/.", -1) // []string{"http://foo.com/"}
rxStrict.FindAllString("no scheme, no match: foo.com", -1) // []string{}
}
```
Note that the funcs compile regexes, so avoid calling them repeatedly.
#### cmd/xurls
