How to parse javascript in PHP page with Java?

Question

I want to retrieve a value of a javascript section in a PHP file with my application in Java.

The PHP page contain something like :

<script type="text/javascript">
var tab= new Array();
    tab[0] = "value0";
    tab[1] = "value1";
    tab[2] = "value2";
</script>

I'm using jsoup for parsing the HTML tag. I tried to use Rhino but I don't find example.

Context context = Context.enter();
Scriptable scope = context.initStandardObjects();
Object result = null;
Reader reader = new InputStreamReader(inputStreamOfThePage);
result = context.evaluateReader(scope, reader, "page", 1 , null );
Scriptable varValue = (Scriptable)scope.get("tab", scope);
String valueStr = (String)varValue .get("tab[0]", varValue );

It's giving me the exception : java.lang.ClassCastException: org.mozilla.javascript.UniqueTag cannot be cast to org.mozilla.javascript.Scriptable

I don't know how to cast the object. Maybe there is a better way to do what I want.

Thanks

Jsoup is not suitable to parse Javascript... It's normal it doesn't work !
