textHandler function

Implementation

Object? textHandler(Parser parser, Element source, {required String selectr}) {
  List<String> results = [];
  if (parser.multiple) {
    // Extract text from all matching elements
    List<Element> selector = source.querySelectorAll(selectr);
    if (selector.isNotEmpty) {
      for (final s in selector) {
        // Handle <br> tags by replacing them with spaces
        if (s.innerHtml.contains("<br>")) {
          String outerHtml = s.outerHtml.replaceAll("<br>", " ");
          Document outerDom = parse(outerHtml);
          results.add(outerDom.body!.text.toString().trim());
        } else {
          results.add(s.text.toString().trim());
        }
      }
      // Remove empty results
      results.removeWhere((value) => value == "");
      return results;
    }
  } else {
