you should be able to do prettyprint(io, elem) to print a reasonably readable representation of an element to an IO (such as an open file, STDOUT, etc.)
:/
julia> prettyprint(io, body)
ERROR: UndefVarError: prettyprint not defined

for (i,(depth, line)) in enumerate(linesof(elem))
if i == maxlines
write(io,". . . \n")
return
else
write(io,repeat(" ",depth)line"\n")
end
end

Closest candidates are:

hmmm, that is very odd, it's definitely there in the latest version (0.1.2):
julia> using Gumbo
julia> prettyprint
prettyprint (generic function with 5 methods)
julia> prettyprint(STDOUT, parsehtml("<h1>Hello, world!</h1>"))
<!DOCTYPE ><HTML>
<head></head>
<body>
<h1>Hello, world!</h1>
</body>
</HTML>
Can you paste the output of Pkg.installed("Gumbo")?

As I said before, I explicitly chose not to support 0.4 while it's under development since the pace of breaking changes is so rapid; I'll make the port to 0.4 after it's released.
I'll close this for now, feel free to reopen if you find anything buggy with this on 0.3 :)
