XML Validator

About XML Validator

Welcome to the free Online XML Validator! This tool helps you check if your XML (Extensible Markup Language) data is "well-formed". A well-formed XML document adheres to all the fundamental syntax rules of XML, such as having a single root element, properly nested tags, and correct attribute syntax.

• Iterative Validation: Finds errors one by one, allowing you to correct them and re-validate immediately. This focused approach is often faster than dealing with a long list of errors at once.
• Instant Validation: Quickly checks your XML for syntax errors.
• Line Numbers: Input and output areas now have line numbers for easy navigation.
• Clear Error Reporting: Pinpoints the exact line and column number where an error is found.
• Error Highlighting: Automatically highlights the problematic line in your code.
• Secure & Private: All validation is done on our server; your data is not stored or shared.

• Web Developers: Ensuring configuration files (e.g., `web.xml`) or data feeds are correct.
• Data Analysts: Validating XML data sources before processing.
• Students: Learning the structure and syntax of XML.
• Anyone working with XML: A quick and easy way to debug XML files.

1. Paste your XML code into the top input area. The line numbers will help you navigate.
