A

If you want to dump all HTML elements of a Web page with WebDriver, you can search child element recursively using the By.xpath() method.

Here is an example program that dumps all HTML elements of the loaded Web page.

// DumpElements.java
// Copyright (c) FYIcenter.com 
import org.openqa.selenium.*;
public class DumpElements {
   public static void main(String[] args) {
      WebDriver driver = WebDriverLoader.load(args[0]);
      driver.get("http://sqa.fyicenter.com");
	  WebElement html = driver.findElement(By.tagName("html"));
	  printTag(html,"");
      driver.quit();
   }
   
   public static void printTag(WebElement tag, String space) {
	  java.util.List<WebElement> list = tag.findElements(By.xpath("./*"));
	  if (list==null) {
		 System.out.println(space+"<"+tag.getTagName()+"/>");
	  } else {
		 System.out.println(space+"<"+tag.getTagName()+">");
         for (WebElement child: list) {
			printTag(child,space+"  ");
         }
		 System.out.println(space+"</"+tag.getTagName()+">");
	  }
   }
}

Compile and run the program, you will see that all elements of the Web page are dumped in the output:

C:\fyicenter> javac -classpath \
   .;\fyicenter\selenium\java\client-combined-3.141.59.jar \
   DumpElements.java

C:\fyicenter> java -classpath \

        </p>
        <p>
...		
      </div>
    </div>
  </body>
</html>

The output looks good. But element attributes are not included in the output. See the next tutorial on how the dump HTML attributes.
