title: node.js variables will not be parsed
body: <p>i am new in node.js and express.</p>
  
  <p>in my test app the html variables will not be parsed.
  what is the problem?</p>
  
  <p>server.js</p>
  
  <pre><code>enter var express = require('express');
  var bodyParser = require('body-parser');
  var app = express();
  
  app.use(bodyParser.urlencoded({
      extended : true
  }));
  
  app.use(express.static(__dirname));
  
  app.get('/', function(req, res) {
      res.render('index', {
          wert : 'hallo'
      });
  });
  
  app.post('/', function(req, res) {
      var wert = req.body.wert;
      var html = 'Hallo: '+wert+'!\n'
      + '&lt;a href="/"&gt;Mach\'s nochmal!&lt;/a&gt;';
      res.send(html);
  });
  app.listen(8882);
  console.log('Server port: 8882');
  </code></pre>
  
  <p>index.html:</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html&gt;
  &lt;head&gt;
  &lt;meta charset="ISO-8859-1"&gt;
  &lt;title&gt;Startseite&lt;/title&gt;
  &lt;/head&gt;
  &lt;body&gt;
  &lt;p&gt;Hallo &lt;%= wert %&gt;, dies ist mein kleiner Webserver!&lt;/p&gt;
  &lt;br&gt;
      &lt;form action="/" method="post"&gt;
          &lt;input type="text" width="40" name="wert" value="&lt;%= wert %&gt;"&gt; 
          &lt;input type="submit" value="submit"&gt;
      &lt;/form&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>the value parameter &lt;%= wert %> in the view is not parsed.
  why? how to do it?</p>
