<![CDATA[<div>Hi, my name is Louie. I'm a great looking houndthat really really wants his next home to be his final loving one. I'm looking for an adult home that will have patience with me as I learn to trust humans again. I like other dogs and tolerate cats. I've got lovely big front feet - just like a Basset should have. I walk well on a leash, and I'm house-trained. I'm a shy boy but I warm up once I get to know you and with lots of love and patience I'm sure in no time I'll turn into a hound that is a happy-go-lucky boy. I'm up to date on all vaccines and my adoption fee is $200.00. Please consider meeting me - I think once you do you will want to take me home and love me for the rest of my life. </div> <br/><a href="http://www.petfinder.com/petdetail/19575609">View this pet on Petfinder.com</a> ]]>

The code I am trying to use is below. the attribute I am trying to return is the url.
void processXML(XElement _xml)
{
XNamespace ns = "";
var pets = from item in
_xml.Elements(ns + "pets").Elements(ns + "pet")
select item;
foreach (var pet in pets)
{
Pet _pet = new Pet();
_pet.id = (string)pet.Element(ns + "id");
_pet.breeds = (string)pet.Ele开发者_开发知识库ment(ns + "breeds").Element(ns + "breed");
_pet.name = (string)pet.Element(ns + "name");
_pet.animal = (string)pet.Element(ns + "animal");
**_pet.media = (string)pet.Element(ns + "media")
.Element(ns + "photos").Element(ns + "photo")
.Attribute(ns + "fpm");**
Results.Items.Add(_pet);
}
}
Thanks in advance for any guidance.

If I understand you have to do something like this:
XmlElement photoList=pet.Element(ns + "media").Element(ns + "photos");
var url = from i in photoList.Descendants("photo")
where i.attribute("size").Equals("fpm")
select i.value;
In this moment I cannot compile it but I think it is a good starting point!
updated
void processXML(XElement _xml)
{
var pets = from item in
_xml.Elements("pet")
select item;
foreach (var pet in pets)
{
//Pet _pet = new Pet();
string id = (string)pet.Element("id");
string breeds = (string)pet.Element("breeds").Element("breed");
string name = (string)pet.Element("name");
string animal = (string)pet.Element("animal");
/*string media = (string)pet.Element(ns + "media")
.Element(ns + "photos").Element(ns + "photo")
.Attribute(ns + "fpm");*/
var url = from i in pet.Descendants().Elements("photo")
where i.Attribute("size").Value.Equals("fpm")
select i.Value;
//Results.Items.Add(_pet);
}
}
