xsd-schema-validator

A (XSD) schema validator for NodeJS that uses Java to perform the actual validation. ➡️ Why?

Prerequisites

Under the hood, this utility uses Java to do the actual validation.

It assumes that javac and java are on the path. If a JAVA_HOME environment variable exists it uses that to locate an installed JDK.

On some platforms, i.e. Mac OSX you need to define JAVA_HOME manually.

Installation

Install the package via npm:

npm install --save xsd-schema-validator

Usage

Use in your application:

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

var xmlStr = '<foo:bar />';

try {
  const result = await validator.validateXML(xmlStr, 'resources/foo.xsd');

  result.valid; // true
} catch (err) {
  console.error('validation error', err);
}

You may validate readable streams:

var xmlStream = fs.createReadableStream('some.xml');

const result = await validator.validateXML(xmlStream);

You may validate files, too:

const result = validator.validateXML({ file: 'some.xml' }, ...);

Why

Because Java can do schema validation and NodeJS cannot.
