Overview

Structural whitespace dimension

Handles comparison of structural whitespace (whitespace between elements). Supports :strict, :normalize, and :ignore behaviors.

Behaviors:

  • :strict - Exact whitespace comparison

  • :normalize - Collapse whitespace and compare

  • :ignore - Skip structural whitespace comparison

Instance Method Details

#compare_normalize(ws1, ws2) ⇒ Boolean

Normalized structural whitespace comparison

Collapses whitespace in each entry and compares.

Parameters:

  • ws1 (Array<String>) —

    First whitespace array

  • ws2 (Array<String>) —

    Second whitespace array

Returns:

  • (Boolean) —

    true if normalized structural whitespace is equal

def compare_normalize(ws1, ws2) # rubocop:disable Naming/PredicateMethod
  normalize_whitespace(ws1) == normalize_whitespace(ws2)
end

#compare_strict(ws1, ws2) ⇒ Boolean

Strict structural whitespace comparison

Parameters:

  • ws1 (Array<String>) —

    First whitespace array

  • ws2 (Array<String>) —

    Second whitespace array

Returns:

  • (Boolean) —

    true if structural whitespace is exactly equal

end

#extract_data(node) ⇒ Array<String>

Extract structural whitespace from a node

Returns whitespace text nodes that are between elements (structural).

Parameters:

  • node (Moxml::Node, Nokogiri::XML::Node) —

    Node to extract from

Returns:

  • (Array<String>) —

    Array of structural whitespace strings
