can not run the second alert

I do not know why this simple code although it was meant to be for education purpose so please me help identify the thing that I have made wrong:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
                "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
  <head>
    <title>Random thoughts part one</title>
    <meta http-equiv="content-type" content="text/html;charset = utf-8" />
    <meta name="keywords" content="thoughts, random, philosophy, mohamed, samir ,sameer, muhammad , mohammed samir" />
    <meta name="description" content="This is a personal page about Mohamed Samir khalil that contain his thoughts and believes" />
    <link rel="stylesheet" type="text/css" href="style.css">
      <body>
        <script type="text/javascript">//
            <![CDATA[

                    alert("hello");
                    var target = document.getElementById("unique_element");
                    alert(target.length);
            //]]>
        </script>
        <center>
          <h3>Random thoughts</h3>
        </center>
        <p id="unique_element">I do not think it is coincidence, because every time I walk in streets I have that strong feeling that keeps telling me &#8221;Man, you have to help people!&#8221;.</p>
        <p>In the beginning I thought that because of thinned for recognition I mean I do this just to hear people say &#8220;thank you&#8221; and to hear people say &#8220;it is great thing that you
        are between us&#8221; so I thought it is all about ego, but you know when I really realized that it is not about ego!</p>
        <p>I realized that when I helped someone and they did not say thank you, what was supposed to happen is that , I should feel anger because it is all about ego, right?</p>
        <p>But what really happened that I felt happy just to help now people who are reading this will say either &#8220;you are so kind&#8221; or &#8220;Okay, you want to make it up huh!&#8221;but
        the reality is just neither this or that ; actually I realized that I am helping people because this is what make us humans and this thing let us feel that we are not alone in this world so
        it is kind of socializing too and also when you help people, I guarantee that someday someone will help you in a very tough situation and he or she will come out of nowhere this is the rule
        of life and this is how people should live.</p>
      </body>

Your script runs before the DOM is parsed so:

var target = document.getElementById("unique_element");

won't return the HTML element and target.length will simply fail. Try to put the JavaScript part before the closing </body>-tag.

You are trying to show the length of a DOM Element. Try alert(target.innerHTML.length); instead.
