Frequently Asked Questions
What is well-formed XML?+
Well-formed XML follows strict syntax rules: every opening tag must have a closing tag, tags are case-sensitive, attributes must be quoted, and there must be exactly one root element. Unlike HTML, browsers won't tolerate syntax errors in XML.
Is XML still relevant?+
Yes. While JSON dominates web APIs, XML is still critical in enterprise systems (SOAP), configuration files (Maven, Android), document formats (DOCX, SVG), and data exchange standards (RSS, XHTML, HL7 in healthcare).
