在HarmonyOS NEXT开发中ohos.xml写好xml后怎么以文件形式存起来？问题描述

// 1.基于Arraybuffer构造XmlSerializer对象 
let arrayBuffer: ArrayBuffer = new ArrayBuffer(2048); // 创建一个2048字节的缓冲区 
let thatSer: xml.XmlSerializer = new xml.XmlSerializer(arrayBuffer); // 基于Arraybuffer构造XmlSerializer对象 
 
thatSer.setDeclaration(); // 写入xml的声明 
thatSer.startElement(‘bookstore’); // 写入元素开始标记 
thatSer.startElement(‘book’); // 嵌套元素开始标记 
thatSer.setAttributes(‘category’, ‘COOKING’); // 写入属性及属性值 
thatSer.startElement(‘title’); 
thatSer.setAttributes(‘lang’, ‘en’); 
thatSer.setText(‘Everyday’); // 写入标签值 
thatSer.endElement(); // 写入结束标记 
thatSer.startElement(‘author’); 
thatSer.setText(‘Giada’); 
thatSer.endElement(); 
thatSer.startElement(‘year’); 
thatSer.setText(‘2005’); 
thatSer.endElement(); 
thatSer.endElement(); 
thatSer.endElement();
