Parse an XML file and put the data into arrays for use in an ExcelTemplate report.

The parseXml method of this demo reads an XML file and parses it using XML DOM.  The data is read into an array of type Object[][], and then bound to the report with the BindData method.


This sample requires OfficeWriter Enterprise Edition to be installed because the OfficeWriter Grouping and Nesting is only available in the Enterprise Edition of the product.
