"How to Get Element by Tag Name In Selenium is a crucial locator that can be used when attribute values like ID, class or name are not available. This locator uses the tag name of an element to locate it in a web page. A tag name is a part of a DOM structure where every element on a page is defined via a tag like input tag, button tag, or anchor tag etc. The command to identify an element via tag name in Selenium is driver.findElement(By.tagName("input")); This locator can be used when you do not have attribute values like ID, class or name and you tend to locate an element. For example, in case you wish to retrieve data from a table, you may use <td> tag or <tr> tag to retrieve data. Similarly, in a scenario where you wish to verify the number of links and validating whether they are working or not, you can choose to locate all such links through the anchor tag. However, using this locator alone without attribute values like ID, class or name may lead to multiple elements being identified as Selenium will select or locate the first tag that matches the one provided from your end. Therefore, it is recommended to use this locator in combination with other locators like XPath, CSS selectors, or attribute value locators when available."
