Extract date out of multiline output in Go

Please see the output of the net use command below. Now I want to extract the expiration date out of this piece of text. Unfortunately the net use command is unable to output as json, xml or whatever parsble format. Therefore I'm stuck to this text :(. I'm only interested in getting 10-6-2017 6:57:20 and convert it into Golang date format.

The problem: I don't know how to start? First find the row which contains "Password expires"? And then what?

User name                    jdoe
Full Name                    John Doe

Country code                 (null)
Account active               Yes
Account expires              Never

Password last set            1-5-2017 6:57:20
Password expires             10-6-2017 6:57:20
Password changeable          1-5-2017 6:57:20
Password required            Yes
User may change password     Yes

Here you go:

import (
	"fmt"
	"strings"
)

func main() {
	str := `
User name                    jdoe
Full Name                    John Doe

Password last set            1-5-2017 6:57:20
Password expires             10-6-2017 6:57:20
Password changeable          1-5-2017 6:57:20
Password required            Yes
User may change password     Yes`

	lines := strings.Split(str, "\n")

	for _, line := range lines {
		if strings.HasPrefix(line, "Password expires") {
			elems := strings.Split(line, " ")
			date := elems[len(elems)-2]
			time := elems[len(elems)-1]
			fmt.Println(date, time)
		}
	}
}

Alternatively you could use regex.

For example, assuming dd-mm-yyyy, 24-hour clock, and local time location (Amsterdam),

package main

import (
	"bufio"
	"fmt"
	"strings"
	"time"
)

func passwordExpires(netuser string) time.Time {
	const title = "Password expires"
	scanner := bufio.NewScanner(strings.NewReader(netuser))
	for scanner.Scan() {
		line := scanner.Text()
		if !strings.HasPrefix(line, title) {
			continue
		}
		value := strings.TrimSpace(line[len(title):])
		format := "2-1-2006 15:04:05"
		loc := time.Now().Location()
		expires, err := time.ParseInLocation(format, value, loc)
		if err == nil {
			return expires
		}
	}
	return time.Time{}
}

// Europe/Amsterdam
var netuser = `User name                    jdoe
Full Name                    John Doe

func main() {
	expires := passwordExpires(netuser)
	fmt.Println(expires)
	if expires.IsZero() {
		fmt.Println("no password expiration")
	}
}

Output:
