How to get attribute value from XML in .NET C#?

Question

I am developing a framework, where I need to get the value of the attribute from a line(string) given string of attribute in C#. Example:Here is the XML <av:Button Name="btn_1" Width="80" Height="25" x:Uid="btn_1" av:Canvas.Left="168.1" av:Canvas.Top="95.1" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">My Button Content</av:Button>

When input is Name, it should return btn_1. When input is Width, it should return 80.

PS: I have implemented this using some hard-coded positions of words, but it fails sometime. -TIA

I would use Linq to XML. It's very easy to use

        String MyXml = "<av:Button Name="btn_1" Width="80" Height="25" x:Uid="btn_1" av:Canvas.Left="168.1" av:Canvas.Top="95.1" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">My Button Content</av:Button>";

        XmlNamespaceManager mngr = new XmlNamespaceManager(new NameTable());
        mngr.AddNamespace("av", "http://www.w3.org/2001/XMLSchema-instance");

        XmlParserContext parserContext = new XmlParserContext(null, mngr, null, XmlSpace.None);

        XmlTextReader txtReader = new XmlTextReader(MyXml, XmlNodeType.Element, parserContext);

        var doc = XElement.Load(txtReader);

        var name = doc.Attribute("Name").Value;
        var width = doc.Attribute("Width").Value;

Thanks James, But I am unable to get x:Uid, Canvas.Left etc. Can you please make it bit generic, I mean handle Namespaces properly.
