I have a DNS query that is returning the fields I need, but now I need to parse a 3 digit number from the response.
The reponse block I am parsing looks like this:
_ref: "network/ZG5zLm5ldHdvcmskMTAuMC45MS4wLzI0LzA:10.0.91.0/24/default"
comment: "Vlan xyz site number 777 "
network: "10.0.91.0/24"
network_view: "default"
This looked like the right regexp, but I'm not getting a response:
re := regexp.MustCompile("[0-9]+")
fmt.Println(re.FindAllString("%s", -1))
Check the documentation for regexp.FindString(string) to make sure you've got the arguments right; you should be giving it the search string...
re := regexp.MustCompile(`\d{3}`)
search := "Vlan xyz site number 777 "
match := re.FindString(search)
fmt.Printf("OK: %q
", match)
// OK: "777"
