如何在angular 4中将xml转换为json？

npm install xml2js --save

import * as xml2js from 'xml2js';

convertXmlToJson(xml: string): Promise<any> {
  return new Promise((resolve, reject) => {
    const parser = new xml2js.Parser({ explicitArray: false, mergeAttrs: true });

    parser.parseString(xml, (err, result) => {
      if (err) {
        reject(err);
      } else {
        resolve(result);
      }
    });
  });
}

const xml = `<root>
  <item id="1">Item 1</item>
  <item id="2">Item 2</item>
</root>`;

this.convertXmlToJson(xml).then((json) => {
  console.log(json);
})
.catch((err) => {
  console.error(err);
});
