I'd like to feed The Ruby Racer a string that looks like, say, this:

<html>
  <body>
    <script>
      document.write("Hello World");
    </script>
  </body>
</html> 

...and, in that case, get back a string that looks like this:

<html>
  <body>
    Hello World
  </body>
</html>

Is that possible? It's not obvious to me from the docs.

Many thanks,

Steven.

Steven,

The ruby racer only embeds a javascript interpreter. It does not parse DOM. You’re probably better off with PhantomJS if you want to deal with full HTML documents server side.

cheers,
Charles
