I use XQuery as static site generator. It is a w3c standard.

You just write the HTML and then it replaces $variables with data, e.g.:

     <html><head>
       <title>{$title}</title>
     </head><body>
       <h1>{$title}</h1>
       <div class="main">{$content}</div>
       ...

It has for loops and functions, too
