Use this free online XML validator (aka XML Lint) tool to perform syntax checks and validate XML using schema validation (XSD + DTD). Copy, Paste, and Validate.
XML Validator also referred to as XML Lint, is a tool used to validate XML (eXtensible Markup Language) data against a specified set of rules and guidelines, such as a schema (such as DTD or XSD). The main purpose is to check if the XML data is well-formed and structured with correct syntax and validate the data, adhering to specified rules and guidelines.
The validity and accuracy of XML are essential for efficiently operating the numerous systems that use it for data exchange. An XML validator checks the XML document for correctness and flags any mistakes or deviations from the schema, which can then be fixed to guarantee the accuracy and consistency of the data. Utilizing this tool makes it easier to make sure that XML data is accurate and consistent, which can increase data reliability and prevent data corruption.
XML Validator is used in various applications such as in web development, software development, and data exchange between different systems where data needs to be stored and exchanged in a structured format. It is also used to validate XML-based file formats, such as XML Schema, XHTML, and SVG, among others.
XML (eXtensible Markup Language) is a markup language used for describing, structuring, and storing data in a way that is both human-readable and machine-readable. XML allows users to define their own tags, making it highly flexible and adaptable to different data structures and requirements. It's widely used for data storage and exchange, particularly in web services.
An XML Schema is a set of rules and standards used to define the structure and content of an XML document. It provides a blueprint for the structure of the document and helps to ensure that the document conforms to the specified rules and standards.
DTD stands for Document Type Definition, and it is a set of rules for validating XML documents that define the structure and content of an XML document by specifying the elements, attributes, and data types that can be used in the document.
An XML Validator is a software tool that verifies the syntax and structure of an XML document. The validator checks if an XML document follows the rules and guidelines specified in its associated XML schema or Document Type Definition (DTD). If the document does not conform to the schema or DTD, the validator will flag the errors, indicating what is incorrect and where the errors are located.
It's simple to use an XML validator. The XML document's code can be pasted into the validator tool directly or uploaded. A document validator will scan it to look for any mistakes or inconsistencies. If errors are discovered, the validator will offer comprehensive details on what is incorrect and where the error is. This knowledge can then be applied to fix the issues and guarantee that the XML document is valid and well-formed.
The XML Validator verifies the XML document's syntax by comparing it to a set of guidelines laid out in an XML Schema or DTD. The document's structure, including its tags, attributes, and elements, is examined by the validator and contrasted with the standards outlined in the schema or DTD. If any mistakes or problems are discovered, the validator alerts the user so they can fix them and guarantee the document's quality.
Missing tags, improper element nesting, incorrect attribute values, and incorrect encoding are just a few examples of the various errors that an XML Validator can detect.
No, XML Validator is specifically designed to validate XML documents and is not compatible with other file formats. To validate other file formats, you will need to use a validator specifically designed for other formats like JSON Validator, CSS Validator, YAML Validator, etc.
