code要读取XAML文件：

 public Window1()
        {
            InitializeComponent();

            FlowDocument content = null;

            OpenFileDialog openFile = new OpenFileDialog();
            openFile.Filter = "FlowDocument Files (*.xaml)|*.xaml|All Files (*.*)|*.*";

            if (openFile.ShowDialog() == System.Windows.Forms.DialogResult.OK)
            {
                FileStream xamlFile = openFile.OpenFile() as FileStream;
                if (xamlFile == null) return;
                else
                {   
                    try 
                    { 
                        content = XamlReader.Load(xamlFile) as FlowDocument; 
                        if (content == null) 
                            throw(new XamlParseException("The specified file could not be loaded as a FlowDocument."));
                    }
                    catch (XamlParseException e)
                    {
                        String error = "There was a problem parsing the specified file:\n\n";
                        error += openFile.FileName;
                        error += "\n\nException details:\n\n";
                        error += e.Message;
                        System.Windows.MessageBox.Show(error);
                        return;
                    }
                    catch (Exception e) 
                    {
                        String error = "There was a problem loading the specified file:\n\n";
                        error += openFile.FileName;
                        error += "\n\nException details:\n\n";
                        error += e.Message;
                        System.Windows.MessageBox.Show(error);
                        return;
                    }

                    FlowDocRdr.Document = content;
                }
        }

错误：它会产生错误的新闻在XAML filde是无效的。

Error: It Generates Error that rss in Xaml filde is invalid.

Q1：我怎样才能获得标题和描述从这个XAML文件

Q2: I want my program to go to this link automatically instead of this that i have to save this file on my PC and to give it's path to this code to make it hard coded.

推荐答案

@Gusdor是正确的，我想太多，你说的是的Atom XML提要。 下面是详细的文章与 XML提要 第一条， 第二条

@Gusdor is right, i think too that you are talking about Atom XML Feed. Here are detailed article related to XML Feed Article1, Article2

请阅读这些文章。这是真正的帮助，了解基础知识 RSS 和 SyndicationFeed 。

Please read these articles. These are really helpful to understand basics of RSS and SyndicationFeed.

下面code是：

 XmlReader reader = XmlReader.Create(@"http://link1/myxaml.xml");
SyndicationFeed feed = SyndicationFeed.Load(reader);
var titles = from item in feed.Items
            select new
                {
                item.Title.Text,  
                 };
var descriptions = from item in feed.Items
        select new
            {   
            item.Summary.Text

             };

foreach (var t in titles)
 {
title_textbox.Text += t.Text + "  ";             //Your All Titles Here

 }
foreach (var des in descriptions)
 {
description_textbox.Text += des.Text + "  ";     //Your All Descriptions Here  
 }
