Replace text in strings
suggest changeReplace string with strings.Replace
s := "original string original"
s2 := strings.Replace(s, "original", "replaced", -1)
fmt.Printf("s2: '%s'\n", s2)
s2: 'replaced string replaced'
Last argument in strings.Replace
is max number of replacements. -1
means "replace all".
Replace string with a regular expression
s := "original string original"
rx := regexp.MustCompile("(?U)or.*al")
s2 := rx.ReplaceAllString(s, "replaced")
fmt.Printf("s2: '%s'\n", s2)
s2: 'replaced string replaced'
This shows how to do strings replacements with regular expressions. (?U)or.*al
is a non-greedy ((?U)
flag) regular expression that matches original
string.
We replace all parts of the string matching the regex with a string replaced
.
Regular expression is non-greedy, meaning it matches the shortest possible string as opposed to default greedy match which looks for longest possible match.
