使用dart获取html标记的文本

import 'package:html/parser.dart' show parse;
import 'package:html/dom.dart';

String html = '<div><p>Hello, <strong>World!</strong></p></div>';

Document document = parse(html);

String text = parseText(document.body);

import 'package:html/parser.dart' show parse;
import 'package:html/dom.dart';

void main() {
  String html = '<div><p>Hello, <strong>World!</strong></p></div>';
  Document document = parse(html);
  String text = parseText(document.body);
  print(text);
}

String parseText(Node node) {
  if (node.nodeType == Node.TEXT_NODE) {
    return node.text;
  } else if (node.nodeType == Node.ELEMENT_NODE) {
    Element element = node as Element;
    String text = '';
    for (var child in element.nodes) {
      text += parseText(child);
    }
    return text;
  } else {
    return '';
  }
}
