我如何编辑 XML 文件xml2js

const fs = require('fs');
const xml2js = require('xml2js');
var fn = 'file.xml';
fs.readFile(fn, function(err, data) {
   parser.parseString(data, function(err, result) {
       //result.data[3].removeChild(); ?????
       //result.date[2].name.innerText = 'Raya'; ?????
   });
});

这是行不通的!

要从 JavaScript 对象中删除属性,只需将该属性设置为 undefined:

result.name = undefined;

来自 xml2js 的结果:

{
    "name": "I will get deleted",
    "items": [
        {
            "itemName": "Item 1",
            "itemLocation": "item1.htm"
        },
        {
            "itemName": "Item 2",
            "itemLocation": "item2.htm",
        }
    ]
}

设置为未定义后:

{
    "items": [
        {
            "itemName": "Item 1",
            "itemLocation": "item1.htm"
        },
        {
            "itemName": "Item 2",
            "itemLocation": "item2.htm",
        }
    ]
}

对你来说,这将是

result.data[3] == undefined;

提示:您可以使用 JSON.stringify 来帮助您。
