What is the difference between an absolute and relative path in XPath?
An absolute xpath starts with the / symbol.

Why absolute XPath is not recommended?

Which XPath is better to use?

But, finding elements using XPath is better for locating elements having complex selectors, and is no doubt the most flexible selection strategy.
Which is faster ID or XPath?
Obviously By.id() is faster as compared to By. xpath() as By.id() is fast accessible.
Why * is used in XPath?

xpath(“//input[@name=’Tutorial’]”)). It is always recommended to use relative xpath rather than absolute xpath. In absolute xpath, we need to specify from the root to the desired element so if any of the attributes and its value get changed in between, then our xpath will no longer be correct.
Which is fastest locator?

What does :: mean in XPath?
:: separates an axis name from a node test in an XPath expression.
Why ID is preferred than XPath?

Why dot is used in XPath?
The dot, or period, character (“.”) in XPath is called the “context item expression” because it refers to the context item.

Is XPath faster than DOM?
My personal experience is, DOM are usually more than 10 times faster than XPath or selector API implementation (e.g. Firefox). However, since XPath accept context node, maybe it is best to select a “stable” parent node with DOM and use XPath for the rest job. This can be both high performance and robust.
Can we use text () in XPath?
5) XPath Text() Function
The XPath text() function is a built-in function of selenium webdriver which is used to locate elements based on text of a web element. It helps to find the exact text elements and it locates the elements within the set of text nodes. The elements to be located should be in string form.
