Node.js - 获取单个 XML 值

Question

I am simply trying to output a single value (thumbnail) of an XML file in Node.js. I feel like I am so close but can't figure it out.

var request = require('request');
request('https://boardgamegeek.com/xmlapi/game/1', (error, response, body) => {
    if (error) { return console.log(error); }
    console.log(body.thumbnail);
});

Answer 1

You need a XML parser, for example xml2js :

var request = require('request');
var parseString = require('xml2js').parseString;

request('https://boardgamegeek.com/xmlapi/game/1', (error, response, body) => {
    if (error) { return console.log(error); }
    parseString(body, function (err, result) {
        console.dir(result);
    });
});

Answer 2

Double check by using the console to see all of body Ie:

      console.log(body)

Then you will see the options you have available. Show us what you get and we could be more specific or it may be enough for you to work out at a glance. You are on the right track. It just depends on the data structure that is there for you.
