import org.w3c.dom.*;

/** This is a simple example of using HttpUnit to read
and understand web pages. **/
public class http1 {


    public static void main( String[] params ) {
        try {
            // create the conversation object which
will maintain state for us
            WebConversation wc = new
WebConversation();

            // Obtain the main page on the meterware
web site
           // WebRequest request = new
GetMethodWebRequest(  );
            WebResponse response = wc.getResponse(
"http://localhost:8080/New/test.html");
            WebWindow w =wc.getMainWindow();
            
            String response1 =
response.getLinkWith("").getURLString();
            //
response.getScriptableObject().evaluateExpression("document.write('this
is anoher node ')");
            
wc.getCurrentPage().getScriptableObject().evaluateExpression("document.write('this
is anoher node ')");
             Document doc=
wc.getCurrentPage().getDOM();
            
System.out.println(doc.getElementsByTagName("*").getLength());
        //    
wc.getCurrentPage().getDOM().appendChild(doc.createTextNode("hallo
world"));
            
System.out.println(wc.getCurrentPage().getText());
             System.out.println(response1); 
             System.out.println( "The HttpUnit main
page contains " + response.getTitle()+ " links" );
             System.out.println(
""+wc.popNextAlert());
             System.out.println(
""+wc.popNextAlert());
             System.out.println(
""+wc.popNextAlert());
           // 
System.out.println(wc.getCurrentPage().getText());   
            
response.getScriptableObject().getScriptEngine().evaluateScriptExpression("function
f() { return
(doc.getElementsByTagName(\"*\").getLength()); } 
function f1(x) { var k =8+x;  return k*k;}function
f3() { return 'hello3'; }" );
            
System.out.println(response.getScriptableObject().getScriptEngine().evaluateScriptExpression("f()"));
