You can find the Root Element Name of Xml Map using Aspose.Cells for Node.js via C++ with the XmlMap.getRootElementName() property. The following screenshot shows the root element name of the XML Map in Microsoft Excel.

The following sample code loads the sample Excel file and accesses the first XML Map and prints its XmlMap.getRootElementName() property. Please see the console output of the sample code given below.
const path = require("path");
const AsposeCells = require("aspose.cells.node");
// The path to the documents directory.
const dataDir = path.join(__dirname, "data");
const filePath = path.join(dataDir, "sampleRootElementNameOfXmlMap.xlsx");
// Load sample Excel file having Xml Map
const wb = new AsposeCells.Workbook(filePath);
// Access first Xml Map inside the Workbook
const xmap = wb.getWorksheets().getXmlMaps().get(0);
// Print Root Element Name of Xml Map on Console
console.log("Root Element Name Of Xml Map: " + xmap.getRootElementName());
