XText.NodeType Property

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Gets the node type for this node.

Namespace: System.Xml.Linq
Assembly: System.Xml.Linq (in System.Xml.Linq.dll)

Syntax

'Declaration
Public Overrides ReadOnly Property NodeType As XmlNodeType

public override XmlNodeType NodeType { get; }

Property Value

Type: System.Xml.XmlNodeType
The node type. For XText objects, this value is Text.

Remarks

Because all classes that derive from XObject contain a NodeType property, you can write code that operates on collections of concrete subclass of XObject. Your code can then test for the node type of each node in the collection.

Examples

The following example creates an XML tree that contains a number of types of nodes. It then iterates through the tree, outputting the node type of each node.

Note that Child2 contains an XText node, implicitly converted from the string content.

Dim output As New StringBuilder
' Note that XNode uses XmlNodeType, which is in the System.Xml namespace.
Dim xmlTree As XDocument = _
    <?xml version='1.0'?>
    <!-- a comment -->
    <?xml-stylesheet type='text/xsl' href='hello.xsl'?>
    <Root Att="attContent">
        <Child1>
            <![CDATA[CDATA content]]>
        </Child1>
        <Child2>Text content</Child2>
    </Root>

For Each node As XNode In xmlTree.DescendantNodes
    output.Append(node.NodeType.ToString())
    output.Append(Environment.NewLine)
    If node.NodeType = XmlNodeType.Element Then
        For Each att In DirectCast(node, XElement).Attributes
            output.Append(att.NodeType.ToString())
            output.Append(Environment.NewLine)
        Next
    End If
Next


OutputTextBlock.Text = output.ToString()

StringBuilder output = new StringBuilder();
// Note that XNode uses XmlNodeType, which is in the System.Xml namespace.
XDocument xmlTree = new XDocument(
    new XComment("a comment"),
    new XProcessingInstruction("xml-stylesheet", "type=\"text/xsl\" href=\"hello.xsl\""),
    new XElement("Root",
        new XAttribute("Att", "attContent"),
        new XElement("Child1",
            new XCData("CDATA content")
        ),
        new XElement("Child2", "Text content")
    )
);

foreach (XNode node in xmlTree.DescendantNodes())
{
    output.Append(node.NodeType + Environment.NewLine);
    if (node.NodeType == XmlNodeType.Element)
    {
        foreach (XAttribute att in ((XElement)node).Attributes())
            output.Append(att.NodeType + Environment.NewLine);
    }
}

OutputTextBlock.Text = output.ToString();
