Parsing XML with multiple similar child nodes in C#

Question

My response xml from webservice is like this:

<doc>
<str name="stage1">data1</str>
<date name="stage2">2013-08-23T09:25:12Z</date>
<str name="parent">data3</str>
<str name="stage4">xxx</str>

How to get the value of element stage4. My final output needs to be xxx. I have tried the following code:

Stream stream = r.GetResponse().GetResponseStream();
            XDocument docs = XDocument.Load(stream);

var data = docs.element(doc).element(stage4);

var data = (string)docs.Root.Elements("str")
               .FirstOrDefault(str => (string)str.Attribute("name") == "stage4");

Or with XPath

string data = (string)docs.XPathSelectElement("//str[@name='stage4']");

What if the doc tag is a descendent of another xml. using (string)docs.descendent("doc").XPathSelectElement("//str[@name='stage4']"); seems not working

@user3083435 you can use Descendtants (which looks all descendant elements in file) instead of Elements (which looks only direct children). Or you can specify full path like Root.Element("doc").Elemtents("str")

Thank for your advise. Good to know there are so many ways to parse an xml.
