AXios接受XML格式的webservice并解析成数据格式

import axios from "axios";
let _env = import.meta.env
let url1 = _env.VITE_APP_BASE_API
let url2 = _env.VITE_APP_zhuang_API
async function map(){
  let a=[]
  let d
  let code
  await axios({
    method: 'get',
    url: url1,
    headers: {
      'Content-Type': 'text/xml'
    }
  }).then(res=>{  //调用axios自己封装的接口
    a=res.data 
    console.log(a)
    var pattern=/Value=(.*) Date/i
    code=pattern.exec(a);
    d = parseInt(code[1].replace(/\"/g, ""));
  })
  return d
 
}
const b=await map()     //结果正确返回a
console.log(b);
const mockData = {
  // 横向柱形图
  regionData: {
    regions: [
      { id: 1, name: "华北", value: b },
      { id: 2, name: "东北", value: utils.createRandom(1, 100) },
      { id: 3, name: "华东", value: utils.createRandom(1, 100) },
      { id: 4, name: "中南", value: utils.createRandom(1, 100) },
      { id: 5, name: "西南", value: utils.createRandom(1, 100) },
      { id: 6, name: "西北", value: utils.createRandom(1, 100) },
    ]
  },
