Visual Basic users can use the Language-Integrated Axes in Visual Basic (LINQ to XML)2 instead of using this axis method explicitly.
This method uses deferred execution.
The following example retrieves a collection of two elements, and then retrieves a collection of all descendants of the two elements that have the specified element name.
This example produces the following output:
This is some text where all of the text nodes must be concatenated. This is a second sentence.
The following is the same example, but in this case the XML is in a namespace. For more information, see Working with XML Namespaces.
This example produces the following output:
This is some text where all of the text nodes must be concatenated. This is a second sentence.
