Any recommendation for xml to json for Node.js?
提问by murvinlai
I've installed node-xml but I don't think it works the way I expect. and it doesnt' have example. any recommendation for xml-2-json (js) for node.js? I also looked at xml2js in npm but it is deprecated and people reported that it is broken with the latest node.js
我已经安装了 node-xml，但我认为它不像我期望的那样工作。它没有例子。对 node.js 的 xml-2-json (js) 有什么建议吗？我还在 npm 中查看了 xml2js，但它已被弃用，人们报告说它被最新的 node.js 破坏了
by the way, i'm also using express. :)
顺便说一句，我也在使用快递。:)

There are many xml parsers.
有很多xml 解析器。
Like libxmljsand node-o3-xml. The latter is made and used by Ajax.org so it should be stable.
像libxmljs和node-o3-xml。后者是由 Ajax.org 制作和使用的，因此它应该是稳定的。
As for converting XML to JSON, I would recommend creating an object structure from your xml and then manually calling JSON.stringifyon it. This gives you complete control of how your xml data is turned into JSON.
至于将 XML 转换为 JSON，我建议从您的 xml 创建一个对象结构，然后手动调用JSON.stringify它。这使您可以完全控制如何将 xml 数据转换为 JSON。
You can then either save the JSON in a file/DB or serve it to a request.
然后，您可以将 JSON 保存在文件/数据库中或将其提供给请求。

libxmljsand node-o3-xmlare great and fast, but beware that they both need to compile binary components. And if you are using them for a module that will be used by others, that caveat is even more serious.
libxmljs和node-o3-xml很棒而且速度很快，但要注意它们都需要编译二进制组件。如果您将它们用于其他人将使用的模块，则警告更加严重。
Taking a higher-level view for a moment, remember that node is single-threaded. So, any XML parsing you do is going to block the node process. To me, that means that XML parsing should never be performed in the same process as your main app. Then, once you move XML parsing to a separate process, maybe a little speed can be sacrificed in favor of ease of installation and greater portability.
稍等片刻，请记住节点是单线程的。因此，您所做的任何 XML 解析都会阻塞节点进程。对我来说，这意味着永远不应在与主应用程序相同的进程中执行 XML 解析。然后，一旦您将 XML 解析转移到一个单独的进程中，也许可以牺牲一点速度来简化安装和提高可移植性。
Personally, that's why I use sax.js-- a pure JavaScript SAX parser -- in my feedparserlibrary (if you're parsing RSS/Atom/RDF feeds, please consider trying it -- comments and pull requests are more than welcome). And honestly, when parsing something as big as an RSS feed, there is no discernable speed difference between sax.js and libxmljs. If you're parsing enormous XML files, you may notice a difference, I suppose. But even then, one nice thing about sax.js is the streaming. Unlike libxmljs (last I used it), you can pipe a stream into sax.js rather than having to read the entire XML document into memory. If you're parsing enormous files, you will love that!
就个人而言，这就是我在我的feedparser库中使用sax.js—— 一个纯 JavaScript SAX 解析器的原因（如果你正在解析 RSS/Atom/RDF 提要，请考虑尝试它 —— 非常欢迎评论和拉取请求） . 老实说，在解析像 RSS 提要这样大的内容时，sax.js 和 libxmljs 之间没有明显的速度差异。如果您正在解析巨大的 XML 文件，我想您可能会注意到不同之处。但即便如此，关于 sax.js 的一件好事是流媒体。与 libxmljs（我上次使用它）不同，您可以将流通过管道传输到 sax.js，而不必将整个 XML 文档读入内存。如果您正在解析巨大的文件，您会喜欢的！

As the other poster points out, node-xmltojsis probably the best way to go.
正如另一位海报指出的那样，node-xmltojs可能是最好的方法。
If you did want to use JSONML, I'm not sure why the JQuery plugin in the other answer is being upvoted: there's JSONML for node:
如果您确实想使用 JSONML，我不确定为什么另一个答案中的 JQuery 插件会被点赞：node有JSONML：
npm install jsonml
Example:
例子：
var fs = require('fs'),
parse = require('jsonml').parse;
var jsonML = parse(fs.readFileSync('myfile.xml'));

To convert XML to JSON in Node js, you can use xml2jsonpackage.
要在 Node js 中将 XML 转换为 JSON，可以使用xml2json包。
To install the package:- npm install --save xml2json
要安装软件包：- npm install --save xml2json
Add Code snippet:-
添加代码片段：-
var parser = require('xml2json');
var xml = "<foo attr=\"value\">bar</foo>";
console.log("input -> %s", xml)
// xml to json
var json = parser.toJson(xml);
console.log("to json -> %s", json);
