从远程XML文件检索数据并将其添加到datagrid

Question

I have an XML file that I have no write access to it .. I retrieve it online.

I have the code below, which works fine, but I can't move forward ..

using System.Data;
using System.Xml.Linq;


try
{
    XDocument XMLFile = XDocument.Load(@"http://Domain/path/to/file.xml");
    MessageBox.Show("Remote File Loaded Successfully ...");
    var items = XMLFile.Descendants("item");
    int i = 0;
    foreach (var item in items)
    {
        i++;
        //var title = item.Descendants("title");
        //MessageBox.Show(title.ToString());
    }
    MessageBox.Show("Items Found: " + i);
}
catch(exception ex)
{
    MessageBox.Show("Error: " + ex.Message.ToString());
    MessageBox.Show("Error: " + ex.InnerException.ToString());
}

The problem I'm facing is in the foreach loop. Every root element item has some child elements. I can't figure out how to retrieve those elements!!

Also, I have a grid view, I want to add the result to it, how can I achieve that??

Thank.

EDIT

XML Sample:

<item>
    <title>Title</title>
    <link>http://domain/link</link>
    <description>Some Text</description>
    <pubDate>Wed, 05 Dec 2012 01:29:37 -0500</pubDate>
    <guid isPermaLink="false">Domain_text_INTEGER</guid>
    <category domain="http://domain/link">A</category>
    <category domain="http://domain/link">B</category>
    <category domain="http://domain/link">C</category>
    <category domain="http://domain/link">D</category>
    <category domain="http://domain/link">E</category>
    <coop:keyword>A</coop:keyword>
    <coop:keyword>B</coop:keyword>
    <coop:keyword>C</coop:keyword>
    <coop:keyword>D</coop:keyword>
    <coop:keyword>E</coop:keyword>
    <coop:keyword>Text</coop:keyword>
    <coop:keyword>Text</coop:keyword>
    <coop:keyword>Text</coop:keyword>
    <coop:keyword>Text</coop:keyword>
    <coop:keyword>Text</coop:keyword>
    <coop:keyword>Text</coop:keyword>
    <coop:keyword>Text</coop:keyword>
    <coop:keyword>Text</coop:keyword>
    <coop:keyword>Text</coop:keyword>
    <coop:keyword>Text</coop:keyword>
    <coop:keyword>text integer</coop:keyword>
    <coop:keyword>Text</coop:keyword>
</item>

What I need from it:

• Title
• Link
• Description
• PubDate
• Guid (INTEGER) <= I can get the integer from the string OR text integer

Thanks.

Answer 1

So on your XMLfile XDocument you've got the descendants.

Also create a collection

List<someobject> list = new List<someobject>();

So in your loop

foreach (var item in items)
{
    var someObject = new SomeObject()
    {
        Title = item.Element("title").Value
    }
}

Then bind your collection to the Grid

Answer 2

This MSDN topic could help you. On MSDN they are posted Walk-through of your problem. Both links suggest to use dataset for this:

DataSet dsAuthors = new DataSet("authors");
string filePath = "Complete path where you saved the XML file";
dsAuthors.ReadXml(filePath);
dataGrid1.DataSource = dsAuthors;
dataGrid1.DataMember = "authors";
dataGrid1.CaptionText = dataGrid1.DataMember;

I just copy/paste an example. You need to modify it for your purposes.
