Question

For example, the prxml function prints XML to *out*. I would like to instead capture this output as a String. Here is the typical usage from a REPL:

user> (prxml [:p "Test"])
<p>Test</p>nil

I’d instead like to do:

(def xml (capture-out (prxml [:p "Test"])))

I made up the capture-out function, but I suspect something like it exists, only I’m having trouble finding it in the API or mailing list.

Answer 1

I just discovered the with-out-str from this great blog post detailing XML processing in Clojure.

So the correct implementation of my example is:

(def xml (with-out-str (prxml [:p "Test"])))
