What is XML?

XML (eXtensible Markup Language) is a markup language used to store and transport data in a structured, text-based format. It is both human-readable and machine-readable, and was designed to be self-descriptive and platform-independent.

XML organizes data using custom tags and nested elements, allowing developers to define their own schemas for data representation. It is commonly used in web services, configuration files, document storage, and communication between systems.

Unlike HTML, which has predefined tags, XML allows you to define your own tags based on the data you want to represent. This flexibility makes it suitable for use cases like RSS feeds, Sitemaps, SOAP APIs, Office document formats, and more.

Key Characteristics of XML:

Self-descriptive: XML contains both data and the structure describing the data.
Custom tag definitions: You can define your own tags and structure.
Supports nested data: Easily models hierarchical relationships.
Platform-independent: Can be used across different systems and applications.
Text-based format: Easy to edit, debug, and version-control.

XML is still widely used in enterprise systems and government platforms, despite the rise of JSON in modern web development.

XML Validator – Validate and Clean XML Data

The XML Validator helps you instantly check XML syntax and structure for errors. Whether you're working with config files, web services, or document formats, this tool ensures your XML is well-formed and standards-compliant.

Why Use an XML Validator?

Catch syntax issues early: Detect missing tags, invalid nesting, or unescaped characters before they break your app or API.
Validate config files: Ensure that XML-based settings for tools like Maven, Ant, or Android Studio are properly structured.
Debug web services: Confirm SOAP requests and responses are valid before integrating or deploying.
Avoid runtime failures: Catch malformed XML before it causes unexpected behavior in production.

How to Use the Tool

Paste your XML code into the left editor panel.
Click the “Validate XML” button placed between the editors.
View the validation result in the right panel — with highlighted errors or confirmation messages.

This tool supports large and nested XML documents, gives detailed error messages, and helps you format or clean up your code as needed. It's a must-have utility for developers working on data feeds, configuration files, or legacy systems.
