XML, or Extensible Markup Language, is a markup language specifically crafted for transmitting data and text. Unlike HTML, which focuses on data presentation, XML's primary function is data transmission. Due to its intricacies, XML is often perceived as challenging to comprehend. However, given its significance in numerous websites, having the ability to edit XML files can greatly benefit you.

Pointers
- XML serves as the foundation for various modern Internet languages like RSS, utilized in news feeds, and WAP and WML, employed by mobile devices. Its use in formatting data ensures compatibility across diverse platforms, languages, and applications, enhancing accessibility for web users with disabilities.
- XML was conceived for structuring, storing, and transmitting data exclusively. Its primary focus lies on the data itself rather than its visual presentation. For web page design, HTML or other WYSIWYG (what you see is what you get) web editors can be employed.
- XML files can also be edited using your computer's notepad program or certain word processing and spreadsheet software. Nevertheless, XML editors offer advantages by validating your code and ensuring compliance with a valid XML structure.
