This example is for a document-level customization.
private void WorksheetQueryXmlData()
{
string path = "/order/customer/address";
string namespaces = "xmlns=http://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.");
}
}
Private Sub WorksheetQueryXmlData()
Dim path As String = "/order/customer/address"
Dim namespaces As String = "xmlns=http://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
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.
