def in_node_set?
  instance_variable_defined?(:@in_node_set) ? @in_node_set : true
end

#parse_errors ⇒ Array<String>

Parse-time errors carried alongside the node tree, captured at parse boundaries (Canon::Xml::DataModel.from_xml, etc.) so the diff report can surface libxml-level FATAL conditions that would otherwise be silently swallowed and produce misleading diffs against a partially-loaded tree. See lutaml/canon#130.

Returns:

  • (Array<String>) —

    Parse errors as strings (empty by default)

#text_content ⇒ Object

Return the text content of this node and all descendants. ElementNode concatenates children’s text_content; other nodes (TextNode, CommentNode, etc.) return their value.
