Examples

The following code example demonstrates how to import XML data into a workbook. The example creates a DataSet of customer names and adds an XmlMap based on the XML schema for the DataSet to the XmlMaps collection of the current workbook. The example then calls the XmlImportXml method to import the data into worksheet Sheet1. When the XmlImportXml method is called, the BeforeXmlImport event handler prompts the user to either proceed with or cancel importing the XML, and the AfterXmlImport event handler then reports whether the XML was successfully imported.

This example is for a document-level customization.
