# xurls

[](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.
