Understand XML Without Guessing
XML uses meaningful tags to describe structured information.
Why does XML exist?
XML exists because systems need a structured way to describe information using meaningful tags.
XML means Extensible Markup Language.
It is not mainly about how a page looks.
It is about describing information clearly.
The tag names are chosen to explain the meaning of the data.
That is why XML is common in feeds, sitemaps, exports, configuration files, and integrations.
A simple XML record
<person>
<name>Maya</name>
<city>Calgary</city>
</person>
<person> is the root element in this small example.
<name> describes a piece of information.
Maya is the text value inside the element.
</name> closes the name element.
The structure shows meaning, not visual design.
Meaning
Tags explain what the data represents.
Structure
Elements can contain other elements.
Exchange
Different systems can pass structured data around.
Reading
A person can often understand the file by reading the tag names.
