Frequently Asked Questions

What is XML?
XML (eXtensible Markup Language) is a markup language that defines rules for encoding documents in a format that is both human-readable and machine-readable.
What's the difference between XML and HTML?
XML is stricter than HTML - all tags must be properly closed, case-sensitive, and well-formed. HTML is more forgiving of syntax errors.
How do I handle special characters in XML?
Use XML entities: &lt; for <, &gt; for >, &amp; for &, &quot; for ", and &apos; for '. Or use CDATA sections for literal text.
Can XML contain comments?
Yes, XML supports comments using <!-- comment text -->. Comments can span multiple lines but cannot be nested.
What are XML namespaces?
Namespaces prevent element name conflicts by qualifying names with a URI. They're declared with xmlns attributes.
