Now you Xml File is Live and Sucesfully Hosted.
for viewing  URL of hosted XML file Click (Open Link) it open XML file in new Windows with Complete URL Please Save this URL It needs you in further Steps .

So open Visual Studio and Make a Simple  Project on Windows phone 7 on C#.
you Need a list box with A data Template .List box has Following Code .

<ListBox x:Name="listBox2">
     <ListBox.ItemTemplate>
         <DataTemplate>
              <StackPanel Margin="20" >
                       <TextBlock Text="{Binding FirstName}"/>
                       <TextBlock Text="{Binding LastName}"/>
              </StackPanel>
           </DataTemplate>
        </ListBox.ItemTemplate>
 </ListBox>

Now Add a Class in Project Name Person and Write Following Code

public class Person
    {
        string firstname; string lastname;
        int age;
        public string FirstName
        {
            get { return firstname; }
            set { firstname = value; }
        }
        public string LastName
        {
            get { return lastname; }
            set { lastname = value; }
        }
        public int Age
        {
            get
            {
                return age;
            }
            set
            { age = value; }
        }
    }

And Here The Method Which Loads XML Data From PHP server.

public void loadXmlFromPHpServer(string xmlUrl, ListBox listbox)
   {
   try
   {
   WebClient client = new WebClient();
   client.OpenReadCompleted += (sender, e) =>
   {
   if (e.Error != null)
   return;
   Stream str = e.Result;
   XDocument xdoc = XDocument.Load(str);
   var filteredData = from c in xdoc.Descendants("Person")
   where c.Attribute("Age").Value == "27"
   select new Person()
   {
   FirstName = c.Attribute("FirstName").Value,
   LastName = c.Attribute("LastName").Value
   };
   listbox.ItemsSource = filteredData;
   textBlock1.Text = "Total Items are Loaded =" + filteredData.Count<Person>();
   };
   client.OpenReadAsync(new Uri(xmlUrl, UriKind.Absolute));
   }
   catch (Exception)
   {

   }
   }
You can Call This Method By Using Following Code on PageLoadEvent or Clcik event of Button Etc.
 loadXmlFromPHpServer("http://muhammadsajjadashrafawan.comyr.com/MohammadSajjadAshrafAwan.xml", listBox2);
