问题 I am trying to extract information from an XML file into an object using LINQ to XML.

问题 I have just started using LINQ to XML, and I am having trouble getting the text contents of a given XElement without getting the text contents of all the child elements as well. So for example, if I have the following XML document: <?xml version="1.0" encoding="utf-8" ?> <root xmlns="example.org/rootns">This is root value <children> <child name='child 1'>value 1</child> <child name='child 2'>value 2 <grandchild name='grandchild A'>value A</grandchild> </child> </children> </root> And I use
