Selenium - Find all elements of a web page

Question

I am planning a tool in Java which would have a drop down containing all the elements of a web page. Is there any way I can read those into a data structure?

Answer 1

Yes, there is a way.

Here is some pseudo-code:

List<WebElement> el = driver.findElements(By.cssSelector("*"));

for ( WebElement e : el ) {
  add(e.tagName());
}

Answer 2

non-pseudo C# version of above: (although I'm just displaying the results in a console

IReadOnlyCollection<IWebElement> el = driver.FindElements(By.CssSelector("*"));
foreach (IWebElement elm in el)
{
    Console.WriteLine(elm.TagName + elm.Text);
}
