Syntax

'Declaration
Public Function XmlDataQuery ( _
    xPath As String, _
    selectionNamespaces As Object, _
    map As Object _
) As Range

public Range XmlDataQuery(
    string xPath,
    Object selectionNamespaces,
    Object map
)

Parameters

xPath
Type: System.String

The XPath to query for.

selectionNamespaces
Type: System.Object

A space-delimited string that contains the namespaces referenced in the XPath parameter. A run-time error is generated if one of the specified namespaces cannot be resolved.

map
Type: System.Object

An XmlMap. Specify an XML map if you want to query for the XPath within a specific map.

Return Value

Type: Microsoft.Office.Interop.Excel.Range
A Range object that represents the cells mapped to a particular XPath; nulla null reference (Nothing in Visual Basic) if the specified XPath has not been mapped to the worksheet, or if the mapped range is empty.

Remarks

XML features, except for saving files in the XML Spreadsheet format, are available only in Microsoft Office Professional Edition 2003 and Microsoft Office Excel 2003.

If the XPath exists within a column in an XML list, the Range object returned does not include the header row or the Insert row.

Optional Parameters

Examples

The following code example uses the XmlDataQuery method to get the Range of cells mapped to a particular XPath.

This example is for a document-level customization.

Private Sub WorksheetQueryXmlData()
    Dim path As String = "/order/customer/address" 
    Dim namespaces As String = "xmlns=https://www.contoso.com/orders" 

    Dim range1 As Excel.Range = _
        Me.XmlDataQuery(path, namespaces)

    If range1 Is Nothing Then
        MsgBox("The specified XPath: '" & path & _
            "' has not been mapped to the worksheet, or the mapped " & _
                "range is empty.")
    End If 
End Sub

private void WorksheetQueryXmlData()
{
    string path = "/order/customer/address";
    string namespaces = "xmlns=https://www.contoso.com/orders";

    Excel.Range range1 = this.XmlDataQuery(path, namespaces);

    if (range1 == null)
    {
        MessageBox.Show("The specified XPath: '" + path + 
            "' has not been mapped to the worksheet, or the mapped " +
            "range is empty.");
    }
}
