Extensions.Nodes(Of T) Method
Returns a collection of the child nodes of every document and element in the source collection.
Assembly: System.Xml.Linq (in System.Xml.Linq.dll)
'Declaration <ExtensionAttribute> _ Public Shared Function Nodes(Of T As XContainer) ( _ source As IEnumerable(Of T) _ ) As IEnumerable(Of XNode) 'Usage Dim source As IEnumerable(Of T) Dim returnValue As IEnumerable(Of XNode) returnValue = source.Nodes()
Type Parameters
- T
The type of the objects in source, constrained to XContainer.
Parameters
- source
- Type: System.Collections.Generic.IEnumerable(Of T)
An IEnumerable(Of T) of XNode that contains the source collection.
Return Value
Type: System.Collections.Generic.IEnumerable(Of XNode)An IEnumerable(Of T) of XNode of the child nodes of every document and element in the source collection.
Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type IEnumerable(Of T). 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 all of the child nodes for every node in a collection of elements with the name of Child.
Dim xmlTree As XElement = _ <Root> <Child>aaa<GrandChild>Text</GrandChild>bbb</Child> <Child>ccc<GrandChild>Text</GrandChild>ddd</Child> </Root> Dim nodes = xmlTree.<Child>.Nodes() ' Note that XNode uses XmlNodeType, which is in the System.Xml namespace. For Each node As XNode In nodes Select Case node.NodeType Case XmlNodeType.Element Console.WriteLine("Element: {0}", DirectCast(node, XElement).Name) Case XmlNodeType.Text Console.WriteLine("Text: {0}", DirectCast(node, XText).Value) End Select Next
This example produces the following output:
Text: aaa Element: GrandChild Text: bbb Text: ccc Element: GrandChild Text: ddd
