What is Document Object Model
Why do we need it
How to use DOM
Demo & Examples
Represents the content of xml or html document as tree structure
Can easily read, access, update the contents of the document
Is a programming interface (API)
All XML elements can be accessed through the XML DOM
xmlDoc.getElementsByTagName("title")[0].childNodes[0].nodeValue;
This code retrieves the text value of the first title element in an XML document
The Document Object Model (DOM) is a programming interface for HTML and XML documents
It represents the page in a tree structure so that programs can read, access and change the document structure, style, and content
The DOM is an object-oriented representation of the web page, which can be modified with a scripting language such as JavaScript.
Every web browser uses some document object model to make web pages accessible via JavaScript

Thank you for the video! It helped me understand what the DOM is about as a beginner. I would like to ask, at 4:20, why is there a need to add in .childNodes[0] when there are no child nodes to title? What is .childNodes[0] pointing at?

Hi Raghav, is it possible to check the html values like padding , color , margins etc using selenium web driver or play wright automation ? Can it be just done manual testing? Thank you
@RaghavPal
Жыл бұрын
Hi Hima, Yes, it is possible to check HTML values like padding, color, margins, etc. using Selenium WebDriver or Playwright automation. Both tools allow you to interact with the web page's HTML elements and retrieve their attributes, including style attributes like padding, color, and margins. For example, in Selenium WebDriver, you can use the getAttribute() method to retrieve the values of any HTML attribute, including style attributes. Here's an example: element = driver.find_element_by_id("my_element") padding_value = element.get_attribute("style") Similarly, in Playwright, you can use the getAttribute() method to retrieve the values of any HTML attribute. Here's an example: const element = await page.$("#my_element"); const paddingValue = await element.getAttribute("style"); While it is possible to check HTML values manually, it can be time-consuming and error-prone. Automating the process with Selenium WebDriver or Playwright can save time and improve the accuracy and consistency of your tests.

So this is how JavaScript can read the html attribute and modify it.. like document.getElementById(//Id value).innerHTML=//write something.. so JavaScript creates this functionality based on from DOM API right?
