nodejs XML和json互相转换

Docs: https://www.npmjs.com/package/fast-xml-parser

const xml = `
  <user>
    <name>ajanuw</name>
    <age>14</age>
</user>
  <user>
    <name>alone</name>
    <age>12</age>
</user>
`;
const fxp = require("fast-xml-parser");
const xml2json = fxp.parse(xml);
console.log(JSON.stringify(xml2json)); // {"user":[{"name":"ajanuw","age":14},{"name":"alone","age":12}]}


const obj  = {
  users: [
   {name: 'ajanuw'},
   {name: 'alone'}
  ]
}

const obj2xml = new fxp.j2xParser().parse(obj)
console.log( obj2xml ) // <users><name>ajanuw</name></users><users><name>alone</name></users>

增加配置

const fxp = require("fast-xml-parser");

const obj = {
  xml: {
    _attrs: {
      version: "1.0.1"
    },
    user: [
      {
        _attrs: {
          key: 1
        },
        name: {
          _cdata: "ajanuw",
          _attrs: {
            age: 14,
            height: 166
          }
        }
      },
      {
        _attrs: {
          key: 2
        },
        name: {
          "#text": "alone",
          _attrs: {
            age: 12
          }
        }
      }
    ]
  }
};

const obj2xml = new fxp.j2xParser({
  format: true,
  attrNodeName: "_attrs",
  textNodeName: "#text",
  cdataTagName: "_cdata"
}).parse(obj);
console.log(obj2xml);

<xml version="1.0.1">
  <user key="1">
    <name age="14" height="166">
<![CDATA[ajanuw]]>
    </name>
  </user>
  <user key="2">
    <name age="12">alone</name>
