Puppeteer

XPath, or XML path, is a query language used for locating a node from a DOM. It is one of the most common ways of identifying an element while writing Selenium UI tests.

In this course, you will learn various techniques for writing an expression that identifies a complex locator. In the process, you will also learn the tips and tricks of writing an efficient and optimized locator. We have used puppeteer with Javascript to demonstrate evaluating an XPath expression in this course.

This course is designed for both beginner and intermediate level developers, as well as QA engineers who want to master the art of writing effective XPath expressions.

Mastering XPath for Selenium

# What is XPath?

**XPath** is a query language for selecting nodes from an XML document. In Selenium for UI test automation, we use XPath to locate a **WebElement** in the DOM (Document Object Model) to interact with and perform any operation on the page. 

# XPath syntax

## Basic components of a WebElement:
 
* HTML Tag
* Attributes

General XPath syntax to identify a **WebElement** in the HTML Document:

```xml
//tagname[@attribute=’Value‘]
```

# Example

Let’s take a look at the HTML webpage snippet and content below to write some basic XPath expressions.

> The example HTML webpage is from the http://codetoautomate.com/xpath-demo-educative/ blog.

Learn the basics of XPath and strengthen your concepts by playing around with a simple example.
