Functions

func EscapeString

func EscapeString(s string) string

EscapeString escapes special characters like "<" to become "&lt;". It escapes only five such characters: <, >, &, ' and ". UnescapeString(EscapeString(s)) == s always holds, but the converse isn't always true.

Example
package main

import (
	"fmt"
	"html"
)

func main() {
	const s = `"Fran & Freddie's Diner" <tasty@example.com>`
	fmt.Println(html.EscapeString(s))
}

Output:

&#34;Fran &amp; Freddie&#39;s Diner&#34; &lt;tasty@example.com&gt;

func UnescapeString

func UnescapeString(s string) string

UnescapeString unescapes entities like "&lt;" to become "<". It unescapes a larger range of entities than EscapeString escapes. For example, "&aacute;" unescapes to "รก", as does "&#225;" and "&#xE1;". UnescapeString(EscapeString(s)) == s always holds, but the converse isn't always true.

Example
package main

import (
	"fmt"
	"html"
)

func main() {
	const s = `&quot;Fran &amp; Freddie&#39;s Diner&quot; &lt;tasty@example.com&gt;`
	fmt.Println(html.UnescapeString(s))
}

Output:

"Fran & Freddie's Diner" <tasty@example.com>
