可能的使用场景
您可以使用C++的Aspose.Cells for JavaScript的XmlMap.rootElementName属性查询XML映射的根元素名称。以下截图显示了Microsoft Excel中XML映射的根元素名称。
示例代码
以下示例代码加载示例 Excel 文件，访问第一个 XML 映射并打印其 XmlMap.rootElementName 属性。请查看下面提供的控制台输出。

<title>Aspose.Cells Example</title>

<body>
<h1>Get Root Element Name Of Xml Map</h1>
<input type="file" id="fileInput" accept=".xls,.xlsx,.csv" />
<button id="runExample">Get Root Element Name</button>
<a id="downloadLink" style="display: none;">Download Result</a>
<div id="result"></div>
</body>
<script src="aspose.cells.js.min.js"></script>
<script type="text/javascript">
const { Workbook, SaveFormat, Worksheet, Cell, Utils } = AsposeCells;
AsposeCells.onReady({
license: "/lic/aspose.cells.enc",
fontPath: "/fonts/",
fontList: [
"arial.ttf",
"NotoSansSC-Regular.ttf"
]
}).then(() => {
console.log("Aspose.Cells initialized");
});
document.getElementById('runExample').addEventListener('click', async () => {
const fileInput = document.getElementById('fileInput');
const resultDiv = document.getElementById('result');
if (!fileInput.files.length) {
resultDiv.innerHTML = '<p style="color: red;">Please select an Excel file.</p>';
return;
}
const file = fileInput.files[0];
const arrayBuffer = await file.arrayBuffer();
// Instantiating a Workbook object using the uploaded file
const workbook = new Workbook(new Uint8Array(arrayBuffer));
// Access first Xml Map inside the Workbook
const xmap = workbook.worksheets.xmlMaps.get(0);
// Get Root Element Name of Xml Map
const rootName = xmap.rootElementName;
// Display result
resultDiv.innerHTML = `<p>Root Element Name Of Xml Map: ${rootName}</p>`;
console.log("Root Element Name Of Xml Map: " + rootName);
});
</script>
