Defined in:
lib/lutaml/xsd/validation/facets/white_space_facet_validator.rb

Overview

Validates and normalizes values against XSD whiteSpace facet

The whiteSpace facet specifies how whitespace should be handled:

  • preserve: All whitespace is preserved

  • replace: Each tab, newline, and carriage return is replaced with a space

  • collapse: Sequences of whitespace are collapsed to a single space, and leading/trailing whitespace is removed

Examples:

Validating whitespace handling

facet = Lutaml::Xsd::WhiteSpace.new(value: "collapse")
validator = WhiteSpaceFacetValidator.new(facet)
validator.valid?("  hello  world  ")  # => true
validator.normalize("  hello  world  ")  # => "hello world"

Constant Summary collapse

PRESERVE = 
"preserve"
REPLACE = 
"replace"
COLLAPSE = 
"collapse"

  when REPLACE
    replace_whitespace(value)
  when COLLAPSE
    collapse_whitespace(value)
  else
    value
  end
end

#valid?(_value) ⇒ Boolean
