❓ Frequently Asked Questions
What is XML and why do I need to format it?
XML (Extensible Markup Language) is a markup language for storing and transporting data. Formatting XML makes it human-readable with proper indentation and structure, making it easier to debug and maintain.
How does the validator work?
Our validator checks for well-formed XML, including proper tag closure, attribute syntax, and XML declaration. It highlights specific errors with line numbers and descriptions to help you fix issues quickly.
What is XPath and how do I use it?
XPath is a query language for selecting nodes in XML documents. Use expressions like //tagname
to select all elements with that tag, or /root/child[@attribute='value']
for specific selections.
Can I convert XML to JSON?
Yes! Click the "Convert to JSON" button to transform your XML into JSON format. This is useful for working with JavaScript applications or APIs that expect JSON data.
What's the difference between formatting and minifying?
Formatting adds proper indentation and line breaks for readability. Minifying removes all unnecessary whitespace to reduce file size, useful for production environments where bandwidth matters.
Is my XML data secure?
Yes! All processing happens directly in your browser using JavaScript. No data is sent to any server, ensuring complete privacy and security of your XML documents.
What are common XML errors to watch for?
Common errors include unclosed tags, mismatched tag names, invalid characters in tag names, missing quotes around attributes, and incorrect XML declaration syntax.
Can I use this tool for large XML files?
Yes, but performance may vary based on file size and browser capabilities. For very large files (>10MB), processing might take longer. The tool works best with files under 5MB.
