I want to add this
<item>
<title>Tony</title>
<link>startk</link>
<description>hi</description>
</item>
我的node.js
var obj = {title: "Tony", link: "Stark" , "description":"hi"};
var fs = require('fs');
var xml2js = require('xml2js');
var builder = new xml2js.Builder();
var xml = builder.buildObject(obj);
fs.writeFile('feed.xml', xml, function (err){
if (err) throw err;
console.log('It\'s saved!');
});
我想替换我的obj中声明的标题标签和链接,但这不起作用。任何人都可以更改我的代码........
最佳答案
在Google上发布此帖子时,我正在寻找稍微不同的东西,但是在这里,我的这段代码应该为遇到此帖子的其他人解决此问题。
function xmlFileToObject(path) {
return new Promise((resolve,reject) => {
getFile(path).then(xml => {
parseXml(xml).then(result => {
resolve(result);
});
});
});
}
function getFile(path) {
return new Promise((resolve, reject) => {
fs.readFile(path, 'utf8', function (err,data) {
if (err) console.error(err);
resolve(data);
});
});
}
function parseXml(xml) {
return new Promise((resolve,reject) => {
var parseString = require('xml2js').parseString;
parseString(xml, function (err, result) {
resolve(result);
});
});
}
