Remove quotes between letters - regex

Question

In golang, how can I remove quotes between two letters, like that:
import (
"testing"
)
func TestRemoveQuotes(t *testing.T) {
var a = "bus\"zipcode"
var mockResult = "bus zipcode"
a = RemoveQuotes(a)
if a != mockResult {
t.Error("Error or TestRemoveQuotes: ", a)
}
}
Function:
import (
"fmt"
"strings"
)
func RemoveQuotes(s string) string {
s = strings.Replace(s, "\"", "", -1) //here I removed all quotes. I'd like to remove only quotes between letters
fmt.Println(s)
return s
}
For example:
"bus"zipcode" = "bus zipcode"

Answer 1

You may use a simple \b"\b regex that matches a double quote only when preceded and followed with word boundaries:
package main
import (
"fmt"
"regexp"
)
func main() {
var a = "\"test1\",\"test2\",\"tes\"t3\""
fmt.Println(RemoveQuotes(a))
}
func RemoveQuotes(s string) string {
re := regexp.MustCompile(`\b"\b`)
return re.ReplaceAllString(s, "")
}
See the Go demo printing "test1","test2","test3".
Also, see the online regex demo.

I am not sure about what you need when you commented I want to only quote inside test3.
This code is removing the quotes from the inside, as you did, but it is adding the quotes with fmt.Sprintf()
package main
import (
"fmt"
"strings"
)
func main() {
var a = "\"test1\",\"test2\",\"tes\"t3\""
fmt.Println(RemoveQuotes(a))
}
func RemoveQuotes(s string) string {
s = strings.Replace(s, "\"", "", -1) //here I removed all quotes. I'd like to remove only quotes between letters
return fmt.Sprintf(`"%s"`, s)
}

In your example you define a string variable so the outer quotes are not part of the actual string. If you would do fmt.Println("bus\"zipcode") the output on the screen would be bus"zipcode. If your goal is to replace quotes in a string with a space then you need to replace the quote not with an empty string as you do, but rather with a space - s = strings.Replace(s, "\"", " ", -1). Though if you want to remove the quotes entirely you can do something like this:
package main
import (
"fmt"
"strings"
)
func RemoveQuotes(s string) string {
result := ""
arr := strings.Split(s, ",")
for i:=0;i<len(arr);i++ {
sub := strings.Replace(arr[i], "\"", "", -1)
result = fmt.Sprintf("%s,\"%s\"", result, sub)
}
return result[1:]
}
func main() {
a:= "\"test1\",\"test2\",\"tes\"t3\""
fmt.Println(RemoveQuotes(a))
}
Note however that this is not very efficient, but I assume it's more about learning how to do it in this case.
