Frequently Asked Questions
- What does an XML formatter do?
- An XML formatter restructures XML code with proper indentation and line breaks to make it readable. It can also minify XML by removing whitespace and comments to reduce file size for production or transmission.
- Does formatting XML change its data?
- No. Formatting only changes whitespace and indentation — the data and structure remain identical. XML parsers treat formatted and minified XML equivalently, so the output will be processed the same way by any application.
- What is the difference between XML and HTML formatting?
- XML is stricter than HTML — all tags must be properly closed, attribute values must be quoted, and tag names are case-sensitive. An XML formatter must preserve this strictness, while HTML formatters can handle the looser HTML syntax. XML also supports CDATA sections and processing instructions that HTML does not.
