Go: Retrieve a string from between two characters or other strings

Let's say for example that I have one string, like this:

<h1>Hello World!</h1>

What Go code would be able to extract Hello World! from that string? I'm still relatively new to Go. Any help is greatly appreciated!

Solution

  • There are lots of ways to split strings in all programming languages.

    Since I don't know what you are especially asking for I provide a sample way to get the output you want from your sample.

    package main

import "strings"
import "fmt"

func main() {
    initial := "<h1>Hello World!</h1>"

    out := strings.TrimLeft(strings.TrimRight(initial,"</h1>"),"<h1>")
    fmt.Println(out)
}

    In the above code you trim <h1> from the left of the string and </h1> from the right.

    As I said there are hundreds of ways to split specific strings and this is only a sample to get you started.

    Hope it helps, Good luck with Golang :)
