Module: Lutaml::Xml::Serialization::FormatConversion

Defined in:
lib/lutaml/xml/serialization/format_conversion.rb

Overview

XML-specific format conversion hooks for Serialize module

This module provides XML-specific serialization logic that extends the format-agnostic Lutaml::Model::Serialize::FormatConversion.

It is prepended into Serialize::ClassMethods when XML format is loaded, overriding the hook methods defined in FormatConversion.

#process_mapping(format, *args) ⇒ Object

Override process_mapping for XML format to handle mapping class inheritance.

When xml SomeMapping is called with a mapping class argument, inherits mappings from the class instead of using a DSL block.

Parameters:

  • format (Symbol) —

    The format

  • args (Array) —

    Additional arguments (mapping class for XML)

  • block (Proc) —

    The DSL block

#validate_document(format, doc, options, register) ⇒ Object

XML-specific document validation: root mapping, encoding, doctype

Parameters:

  • format (Symbol) —

    The format

  • doc (Object) —

    The parsed document

  • options (Hash) —

    Options hash (modified in place)

  end
end

#validate_xml(xml) ⇒ Array<Lutaml::Xml::Error::SchemaValidationError>

Validate a raw XML string against the configured schemas without instantiating a model — the explicit input-side counterpart to the validate/validate! output-side check.

Parameters:

  • xml (String) —

    an XML document

Returns:

def validate_xml!(xml)
  errors = validate_xml(xml)
  raise Lutaml::Model::ValidationError.new(errors) if errors.any?
end

#validate_xml_with(*paths) ⇒ Object

Configure one or more XSD schemas that the model's generated XML must conform to. Checked during validate/validate! (issue #264). Repeated calls (including in subclasses) append.

Relative paths resolve against the file that declares the macro, so a model works regardless of the process working directory.

Parameters:

  • paths (Array<String, Pathname>) —

    paths to XSD schema files

  @own_xml_schema_paths = own_xml_schema_paths +
    paths.flatten.map { |path| File.expand_path(path.to_s, base) }
end

#xml_schema_paths ⇒ Array<String>

All configured XSD schema paths, parent-first: inherited paths come before paths declared on this class.

Returns:

  • (Array<String>)
