How can I inject a if statement in an HTML attribute?

Question

I'm trying to create a go html (Go 1.13) with a context {{.}}.

I've managed to display context variables as div values, but I can't find the right way to put context variables inside HTML attributes.

For instance, this code works:

{{ if .AppCtx.Title }} 
<a href="/">{{ .AppCtx.Title }}</a>
{{end}}

But this does not seem to work :

<a href="{{ if .AppCtx.Link }}{{.AppCtx.Link}} {{end}}">

I' ve tried different syntaxes :

<a href='{{ if .AppCtx.Link }}{{.AppCtx.Link}} {{end}}'>

<a href=""{{ if .AppCtx.Link }}{{.AppCtx.Link}} {{end}}>

<a href="{{ if .AppCtx.Link }}{{.AppCtx.Link}} {{end}}">

I've read https://golang.org/pkg/html/template/ but didn't find any clue in it.

@Peter my condition is true, but once compiled, my html only displays — Fradifrad, Nov 05 '19 at 15:45
Ok, thanks a lot ! The issue must be somewhere else ; I'm looking into it. Now I know my syntax in gohtml is not the issue :) — Fradifrad, Nov 05 '19 at 16:22

Did you mean to do this instead?

<a href="{{ if .AppCtx.Title}}{{.AppCtx.Title}} {{end}}">
