在GOlang中解析XML

I'm learning how to parse XML in GOlang using this lesson: https://astaxie.gitbooks.io/build-web-application-with-golang/content/en/07.1.html I succeeded with getting the result it's shown there:

{{ servers} 1 [{{ server} Shanghai_VPN 127.0.0.1} {{ server} Beijing_VPN 127.0.0.2}]

But how do I get the text from each field? When I'm printing, for example, v.Svs, I get

[{{ server} Shanghai_VPN 127.0.0.1} {{ server} Beijing_VPN 127.0.0.2}].

How do I receive "Shanghai_VPN 127.0.0.1"?

    Assuming you're using the objects from that example, to access the server name and IP of the first item of the list, you would use the following;

    fmt.Println(v.Svs[0].ServerName)
    fmt.Println(v.Svs[0].ServerIP)
    

    In reality you should iterate over the array since you won't know how many objects there are. Here's a working example in play; https://play.golang.org/p/abnc9VaNlO

    With iteration and the output formatting you have above that would be;

    for _, srv := range v.Svs {
         fmt.Println(srv.ServerName + " " + srv.ServerIP)
    }
