How do you escape raw HTML in Go? -

-

i have managed output text using following line:

fmt.fprintf(w, "<p>some text</p>")

but literally output html tags. how output can safely included in html echo in php?

fmt.fprintf() has no knowledge of html syntax: outputs raw data without escaping (it may formatting not escaping).

you don't use correctly though: second parameter format string, should call rather this:

fmt.fprintf(w, "%s", "<p>some text</p>")

else if text contains format-specific special characters, not expected result.

what want escape html code can safely included in html documents/pages. excellent support html/template package provides powerful template engine automatic escaping functionality being 1 feature.

here's simple example how achieve want:

w := os.stdout  text := "<p>some text</p>" fmt.fprintf(w, "%s\n", text)  tt := `{{.}}` t := template.must(template.new("test").parse(tt)) t.execute(w, text)

output (try on go playground):

<p>some text</p> &lt;p&gt;some text&lt;/p&gt;

also note if want escape html code, there template.htmlescaper() function that:

fmt.println(template.htmlescaper(text))

output:

&lt;p&gt;some text&lt;/p&gt;
