generate method

String generate(Map<String, dynamic> data, { Map<String, dynamic>? keyMeta, bool prettyPrint = true, })

Generates XML from data using key metadata for layout preservation.

data - The JSON data map to convert. Expected to contain a single root element key with its content as the value. keyMeta - The key-level metadata for layout information prettyPrint - Whether to format XML with indentation (default: true)

Returns an XML string with preserved layout from the original document.

Implementation

String generate(
  Map<String, dynamic> data, {
  Map<String, dynamic>? keyMeta,
  bool prettyPrint = true,
}) {
  if (data.isEmpty) {
    return '';
  }

  final builder = XmlBuilder();
  builder.processing(
    TurboConstants.xmlProcessingInstruction,
    TurboConstants.xmlDeclaration,
  );

  // Data should have a single root element key
  for (final entry in data.entries) {
    final rootKey = entry.key;
    final rootValue = entry.value;
    final rootMeta = _getKeyMetadata(keyMeta, rootKey);

    _buildElement(
      builder,
      rootKey,
      rootValue,
      rootMeta,
      keyMeta,
    );
  }

  final document = builder.buildDocument();
  return prettyPrint
      ? document.toXmlString(pretty: true)
      : document.toXmlString();
}
