DocumentBase.SelectSingleNode Method

  • Article

Returns a Microsoft.Office.Interop.Word.XMLNode object that represents the first node in the document that matches the XPath parameter.

Namespace:  Microsoft.Office.Tools.Word
Assembly:  Microsoft.Office.Tools.Word.v4.0.Utilities (in Microsoft.Office.Tools.Word.v4.0.Utilities.dll)

Syntax

'Declaration
Public Function SelectSingleNode ( _
    xPath As String, _
    prefixMapping As String, _
    fastSearchSkippingTextNodes As Boolean _
) As XMLNode

public XMLNode SelectSingleNode(
    string xPath,
    string prefixMapping,
    bool fastSearchSkippingTextNodes
)

Parameters

  • xPath
    Type: System.String

    A valid XPath string. For more information about XPath, see XPath Reference.

  • prefixMapping
    Type: System.String

    Provides the prefix in the schema against which to perform the search. Use the PrefixMapping parameter if your XPath parameter uses names to search for elements.

  • fastSearchSkippingTextNodes
    Type: System.Boolean

    true skips all text nodes while searching for the specified node. false includes text nodes in the search. Default value is false.

Return Value

Type: Microsoft.Office.Interop.Word.XMLNode
A Microsoft.Office.Interop.Word.XMLNode object that represents the first node that matches the XPath parameter in the document; nulla null reference (Nothing in Visual Basic) if no nodes matching the XPath parameter are found.

Remarks

Setting the FastSearchSkippingTextNodes parameter to true diminishes performance because Microsoft Office Word searches all nodes in a document against the text contained in the node.

Optional Parameters

For information on optional parameters, see Optional Parameters in Office Solutions.

Examples

The following code example demonstrates how to specify the XPath and PrefixMapping parameters when calling the SelectSingleNode method. To use this example, run it from the ThisDocument class in a document-level project.

Private Sub DocumentSelectSingleNode()
    If Me.XMLSchemaReferences.Count > 0 Then 
        Dim XPath As String = "/x:catalog/x:book/x:title" 
        Dim PrefixMapping As String = "xmlns:x=""" + _
            Me.XMLSchemaReferences(1).NamespaceURI + """" 
        Dim node As Word.XMLNode = Me.SelectSingleNode(XPath, _
            PrefixMapping, True)
    Else
        MessageBox.Show("The document does not contain a " + _
            "schema reference.")
    End If 
End Sub

private void DocumentSelectSingleNode()
{
    if (this.XMLSchemaReferences.Count > 0)
    {
        string XPath = "/x:catalog/x:book/x:title";
        object key = 1;

        string PrefixMapping = "xmlns:x=\"" +
            this.XMLSchemaReferences.get_Item(ref key).NamespaceURI +
            "\"";

        Word.XMLNode node = this.SelectSingleNode(XPath, 
            PrefixMapping, true);
    }
    else
    {
        MessageBox.Show("The document does not contain a " +
            "schema reference.");
    }
}
