Overview

Validates XML schema — well-formedness and XSD schema validity.

This is Layer 4 validation. Two modes:

  • Well-formedness: all XML parts parse without errors
  • XSD validation: parts validated against OOXML XSD schemas

XSD validation uses SchemaRegistry for namespace-aware schema selection. Uses Moxml for namespace detection and Nokogiri::XML::Schema for validation.

Examples:

Validate with XSD

validator = XmlSchemaValidator.new("xml_schema" => { "xsd_validation" => true })
result = validator.validate('/path/to/document.docx')
