How to use dedicated XSD validation library In Javascript

This approach leverages libraries specifically designed for XSD validation in JavaScript. These libraries handle the complexities of XSD validation, often using external tools or parsers.

Installation: Install the library using the following command.

npm i xsd-schema-validator

Example: Implementation to validate XML against XSD using xsd validation library.

JavaScript

const validator = require('xsd-schema-validator');

const xmlString = require('fs').readFileSync('data.xml', 'utf8');
const xsdPath = 'schema.xsd';

validator.validateXML(xmlString, xsdPath)
  .then(result => {
    if (result.valid) {
      console.log("XML is valid!");
    } else {
      console.error("XML is invalid:", result.errors);
    }
  })
  .catch(error => {
    console.error("Validation error:", error);
  });

Output:

XML is valid!

How to Validate XML against XSD in JavaScript ?

XML (Extensible Markup Language) is a widely used format for storing and exchanging structured data. XSD (XML Schema Definition) is a schema language used to define the structure, content, and data types of XML documents. Validating XML against XSD ensures that the XML document conforms to the specified schema.

XML (Extensible Markup Language):

It is a widely used format for structuring and storing data hierarchically.
It is often used for data exchange between different systems or platforms due to its flexibility and platform independence.

XSD (XML Schema Definition):

It acts as a standard for defining the structure, content, and data types of XML documents.
It ensures consistency and integrity by specifying the rules that XML data must adhere to.
