What you’ll learn

  • Select web elements using CSS Tag name/Type, Class, Id and Attribute-Value selectors.
  • Write XPath Expressions to select web elements based on their structure and tag name
  • Use CSS Operators like Starts-with, Ends-with and Contains to select attribute values dynamically.
  • Select web elements using XPath Attribute-Value selectors
  • Select web elements using CSS Parent, Child, Descendant & Sibling selectors.
  • Build XPath Conditions using different operators to create logical selectors
  • Use Special CSS selectors like not( ), nth-child( ), etc. to create efficient selectors.
  • Use XPath Functions to query attribute values (starts-with( ), contains( ), etc. a specific value), select innerText, and use value processor functions.

Description

This course is all about selecting web elements with CSS Selectors & XPath!

When learning about the basic CSS Selectors or XPath, we learn about the tag name selectors, class selectors, id selectors, and that’s it. Most of the web elements can be selected using the selectors mentioned before, but in a real-world project, there is always a demand for more. A better way to do the task i.e. select web elements.


So it’s time you up your game of web element selection and learn about the cool selectors which you’ve never heard of. Whether you want to use CSS Selectors, XPath, or both, after taking this course you’ll write selectors which are accurate, concise, and easy to understand!


As I mentioned at the top, this course is all about SELECTORS! Here’s an overview of what we will cover,

  • CSS Selectors

    • Tagname/Type

    • Class & Id

    • Attribute-Value

    • Hierarchy (Parent, Sibling & Child)

    • starts-with Operator

    • ends-with Operator

    • contains Operator

    • not Function

    • first-child, last-child, or only-child

    • nth-child or Element Position

    • Pseudo Elements

    • Element States

  • XPath

    • Absolute & Relative Path

    • Tagname/Type

    • Position or Index

    • Attribute-Value

    • starts-with( ) Function

    • contains( ) Function

    • Mathematical Operators

    • Conditional Operators

    • Axes ( ancestor, parent, sibling, child, or descendant )

    • Element Position

    • Child Element Count

    • Processor Function ( like round( ), translate( ), etc.)


To show the full potential of each selector, it is introduced with a use case in a real-world example, so that everything fits into place in your mind. You’ll be able to decide which selector to use when in your projects.


Now whether you build web-scrapers to scrape data from websites, front-end developer looking to master CSS Selectors, or use web automation/testing frameworks, if you’re selecting web elements from websites either using CSS, XPath, or both – you should take this course to take your web selection to the next level!
