Question

In my previous question here, I didn’t understand how to solve my problem.
Linq to XML, how to acess an element in C#?
Here is my XML I need to parse:

<root>
         <photo>/filesphoto.jpg</photo>
         <photo:mtime>12</photo:mtime>
         <text>some text</text>
 </root>

To access the element I use this code:

var doc = XDocument.Parse(xml.Text);
doc.Descendants("text").FirstOrDefault().Value;

How can I access ?
I have try http://aspnetgotyou.blogspot.com/2010/06/xdocument-or-xelement-with-xmlnamespace.html,
But it is ignored <photo:mtime> and I need to access it.
Please write some code.

Contrary to @BrokenGlass’ comments, your XML is not invalid. In fact the technique in the link you provided in your question (for loading namespaces) works fine. Maybe you just didn’t change the example for your own needs. Here’s a more compact generalization for parsing xml fragments with namespaces into an XElement:

public static XElement parseWithNamespaces(String xml, String[] namespaces) {
    XmlNamespaceManager nameSpaceManager = new XmlNamespaceManager(new NameTable());
    foreach (String ns in namespaces) { nameSpaceManager.AddNamespace(ns, ns); }
    return XElement.Load(new XmlTextReader(xml, XmlNodeType.Element, 
        new XmlParserContext(null, nameSpaceManager, null, XmlSpace.None)));
}

Using your exact input:

string xml = 
@"<root>
    <photo>/filesphoto.jpg</photo>
    <photo:mtime>12</photo:mtime>
    <text>some text</text>
</root>";
XElement x = parseWithNamespaces(xml, new string[] { "photo" });
foreach (XElement e in x.Elements()) { 
    Console.WriteLine("{0} = {1}", e.Name, e.Value); 
}
Console.WriteLine(x.Element("{photo}mtime").Value);

Prints:

photo = /filesphoto.jpg
{photo}mtime = 12
text = some text
12
