In the only example, I use 'when-not to conditionally display an element.
(deftemplate microblog-template "net/cgrand/enlive_html/example.html"
[title posts]
[:title] title
[:h1] title
[:div.no-msg] (when-not (seq posts) ~(html/show))
[:div.post] (for [{:keys [title body]} posts]
~(at
[:h2] title
[:p] body)))
see:
net.cgrand.enlive-html.examples=> (apply str (microblog-template "Hello user!"
[{:title "post #1"
:body "hello with dangerous chars: <>&"}
{:title "post #2"
:body "dolor ipsum"}]))
/"<html><head><title>Hello user!</title></head>
<body><h1>Hello user!</h1>
<div class=\"post\"><h2>post #1</h2>
<p>hello with dangerous chars: <>&</p></div>
<div class=\"post\"><h2>post #2</h2>
<p>dolor ipsum</p></div></body></html>"
and:
/net.cgrand.enlive-html.examples=> (apply str (microblog-template "Hello
Stuart!" []))
"<html><head><title>Hello Stuart!</title></head><body><h1>Hello Stuart!</h1>
<div class=\"no-msg\">Sorry, I'm too lazy to post.</div></body></html>"
But I'm not sure that's what you are asking for. Do you mean something
else?
(Right now there's no facility to use another element than the currently
selected one but it's planned if that's what you are interested in.)
