Locating elements by tag name


Selenium WebDriver's By class provides a tagName() method to find elements by their HTML tag name. This is similar to the getElementsByTagName() DOM method in JavaScript.

This comes in handy when you want to locate elements using their tag name. For example, locating all <tr> tags in a table and so on.

In this recipe, we will briefly see how to use the tagName locator method.

How to do it...

Let's assume you have a single button element on a page. You can locate this button by using its tag in the following way:

WebElement loginButton = driver.findElement(By.tagName("button"));
loginButton.click();

Take another example where we want to count how many rows are displayed in <table>. We can do this in the following way:

WebElement table = driver.findElement(By.id("summaryTable"));
List<WebElement> rows = table.findElements(By.tagName("tr"));
assertEquals(10, rows.size());

How it works...

The tagName locator method queries the DOM and returns a list of matching elements for the specified tag name. This method may not be reliable while locating individual elements and the page might have multiple instances of these elements.
