#鸿蒙学习大百科#ArkTS如何生成xml？

import xml from '@ohos.xml';
import util from '@ohos.util';
// 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

@Entry
@Component
struct Index {
  build() {
    Column() {
      Button("生成xml").onClick(() => {
        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();
      })
    }
    .width('100%')
    .height('100%')
    .justifyContent(FlexAlign.Center)
  }
