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 \
