Так что это RSS-канал, и это мой код:

import 'package:http/http.dart' as http;
import 'package:xml/xml.dart' as xml;

class Blogs {
  List<BlogModel> blogs = [];

  Future<void> getBlog() async {
    String url = 'http://syndication.eonline.com/syndication/feeds/rssfeeds/topstories.xml';

    var client = http.Client();
    var response = await client.get(url);
    var rssFeed = response.body;
    var raw = xml.parse(rssFeed);
    var elements = raw.findAllElements('item');

    elements.forEach((element) {
      BlogModel blogModel = BlogModel(
        title: element.findElements('title').first.text,
        url: element.findElements('link').first.text, //This is where I want to get the link in the CDATA
        urlToImage: element.findElements('description').first.text, //This is where I want to get the image src..
        description: element.findElements('description').first.text,
      );
      blogs.add(blogModel);
    });
  }
}

Но я не знаю, как получить доступ к строке http sr c в теге изображения.

Также мне нужно получить строку http в CDATA тега ссылки

Answer 1

Этот код должен помочь:

elements.forEach((element) {

   // This will get the image's src.. since it is having problems 
   // with reading the <img>(it is considered as just text 
   // for some reason and not an xml tag).
   // I guess its due to a problem with the encoding of the rss feed
   // So reg-expression has to be used.

   final description = element.findElements('description').first.text;
   final urlRegExp = RegExp(r'(?:(?:https?):\/\/)?[\w/\-?=%.]+\.[\w/\-?=%.]+');
   final imgSrc = urlRegExp.firstMatch(description).group(0);

   // The rest of the parsing.
    BlogModel blogModel = BlogModel(
      title: element.findElements('title').first.text,
      url: element.findElements('link').first.text, //This will get the CDATA content with no problem
      urlToImage: imgSrc,
      description: element.findElements('description').first.text,
    );
    blogs.add(blogModel);
});
