詹妮弗·洛佩兹和迪迪在Instagram直播上重聚，参加了一场马拉松舞会的募捐活动
谁的舞步更好：詹妮弗·洛佩兹还是肖恩·迪迪·库姆斯？星期天，迪迪请他的名人朋友们站起来为一项事业跳舞。在Instagram上发布，…

这就是rss提要，这是我的代码：

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);
    });
  }
}

import'package:http/http.dart'作为http；
将“package:xml/xml.dart”导入为xml；
班级博客{
列出博客=[]；
Future getBlog（）异步{
字符串url='0http://syndication.eonline.com/syndication/feeds/rssfeeds/topstories.xml';
var client=http.client（）；
var response=wait client.get（url）；
var rssFeed=response.body；
var raw=xml.parse（rssFeed）；
var元素=原始的findAllElements（“项目”）；
elements.forEach（（element）{
BlogModel BlogModel=BlogModel(
标题：element.findElements（'title'）.first.text，
url:element.findElements（'link'）.first.text，//这是我想要在CDATA中获取链接的地方
urlToImage:element.findElements（'description'）.first.text，//这是我想要获取图像src的地方。。
description:element.findElements（'description'）.first.text，
);
blogs.add（blogModel）；
});
}
}

但是我不知道如何访问image标记中src的http字符串

此外，我还需要在链接标记的CDATA中获取http字符串。此代码应该有帮助：

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);
});

elements.forEach（（element）{
//这将获取映像的src..，因为它有问题
//在阅读的过程中，我遇到了这个问题，我在这里尝试了解决方案，但当时对我无效
我发现这个函数对我很有用

String removeAllHtmlTags(String htmlText) {
RegExp exp = RegExp(
  r"<[^>]*>",
  multiLine: true,
  caseSensitive: true
);

return htmlText.replaceAll(exp, '');}

Moqbel感谢您的回答，但它没有工作。代码没有返回错误，但仍然没有显示图像。E/flatter（32245）：[error:flatter/lib/ui/ui_dart_state.cc（157）]未处理的异常：错误状态：无元素E/flatter（32245）：#0 Iterable.first（dart:core/Iterable.dart:520:7）E/flatter（32245）：#1.getBlog。（软件包：teens#u news/helper/blogs.dart:32:53）E/flatter（32245）：#2 Iterable.forEach（dart:core/Iterable.dart:279:30）E/flatter（32245）：#3 blogs.getBlog（软件包：teens#u news/helper/blogs.dart:27:17）这真的很奇怪，因为我已经对它进行了测试，它工作得很好。我能想到的唯一解释是，可能您输入代码的xml内容不正确。您发布的xml文件几乎没有问题，我必须清理它，所以我将所有内容都分条，并留下标记，因为它不平衡。这可能就是原因。您可以吗使用API获取xml内容？不，先生，我使用rss源从网站获取xml文件。因此，我非常确定xml文件是正确的，先生，问题是我的代码，您的代码没有返回e
 Response response = await get(
      'your_link',);
     

  if (response.statusCode == 200) {
    var raw = XmlDocument.parse(response.body);
    var elements = raw.findAllElements("stock_available");
    productStock.addAll(elements.map((e) {
      final id = e.findElements('id').single.text;
   
      return StockAvailableProduct(
          id: int.parse(removeAllHtmlTags(id)),
          idProduct:
              removeAllHtmlTags(e.findElements('id_product').single.text),
          idProductAttribute: removeAllHtmlTags(
              e.findElements('id_product_attribute').single.text),
          idShop: removeAllHtmlTags(
              e.findElements('id_shop_group').single.text),
