Extracting data from strings
You can use a regular expression to locate and extract text that occurs within a pattern.
How to do it...
Use capture groups to extract substrings that match a pattern.
How it works...
package main
import (
     "fmt"
     "regexp"
)
func main() {
     re := regexp.MustCompile(`^(\w+)=(\w+)$`)
     result := re.FindStringSubmatch(`property=12`)
     fmt.Printf("Key: %s value: %s\n", result[1], result[2])
     result = re.FindStringSubmatch(`x=y`)
     fmt.Printf("Key: %s value: %s\n", result[1], result[2])
} Here is the output:
Key: property value: 12 Key: x value: y
Let’s look at this regular expression:
^(\w+): A string composed of one or more word characters at the beginning of the line (capture group 1)
