DocumentBase.SelectSingleNode Method (String, String, Boolean)

 

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)

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; null if no nodes matching the XPath parameter are found.

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.

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

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 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.");
    }
}
