Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type IEnumerable<XElement>. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).The following example retrieves a collection of elements, which in this case includes the Child1 and Child2 elements. It then retrieves all attributes of that child collection with a name of Att1.
XElement xmlTree = new XElement("Root", new XAttribute("Att1", "content1"), new XAttribute("Att2", "content2"), new XElement("Child1", new XAttribute("Att1", "content3"), new XAttribute("Att2", "content4") ), new XElement("Child2", new XAttribute("Att1", "content5"), new XAttribute("Att2", "content6") ) ); IEnumerable<XAttribute> attList = from att in xmlTree.Elements().Attributes("Att1") select att; foreach (XAttribute att in attList) Console.WriteLine(att);
This example produces the following output:
Att1="content3" Att1="content5"
