Xpath In Selenium


Xpath in Selenium


XPath (XML Path Language) is a query language for selecting elements from an XML/HTML document.

It helps you find an element from the whole document precisely and quickly.

Web pages are generally written in a language called HTML. If you load a web page on a browser (Chrome, Firefox, etc), you can easily access the corresponding HTML doc by hitting the F12 key.

Before going to create a Xpath, we need to understand few basic terms.

 What is meant by nodes in Xpath ?
  • In XPath, there are many kinds of nodes for example element node, attribute node, text node, namespace, Text, processing-instruction, comment, and document nodes .
  • XML documents are treated as trees of nodes. The topmost element of the tree is called the root element.
  • Few example of nodes except root node.
    • Element node: represents the HTML element, i.e an HTML tag.
    • Attribute node: it represents an attribute in an element node, e.g. “href” attribute in <a href=”http://www.selenium.com”>example</a>
    • Comment node: represents comments in the HTML document which is denoted by (<!– … –>)
    • Text node: represents the text enclosed in an element node (example in <p>example</p>)


 What is meant by Atomic values in Xpath ?
  • Atomic values are nodes with no children or parent.


 What is meant by Items in Xpath ?
  • Items are atomic values or nodes.


 Apart form this you should also understand the relationship between nodes
