Don’t worry, if you have sensitive data that you want to quickly format. You can rest easy knowing that your information will never be saved, shared stored or even transmitted to our own servers here at XmlLint. All XML data processing will occur within your own browser only.

• Don't forget the root tag- Remember, XML is like a tree structure and needs a single root element in place.
• It’s important to note that duplicate attribute names within a tag are not permitted with XML.
• XML is NOT HTML. XML does not recognize self-closing tags like HMTL, so be sure to close all tags!
• Be sure to follow all XML rules. Unsure of the rules? No problem – you can read them here.

Formatting across Operating Systems

Your XML might not validate if you copy text from a file that was saved on an operating different than what you are currently working on. This is due to the fact that Windows and Linux/Mac use a differnt ways to indicate a new line. The Windows operating system family uses two characters \r\n (carriage-return and newline), whereas Linux and Mac systems only use a single \r character. If you are encountering this problem, simply use the newline character that your current OS expects. For more details as to why this is still an issue in 2020, please visit this page.
