xml2js从URL读取 [英] xml2js read from url

问题描述

所以我有NodeJS并安装了模块xml2js.在本教程中，我们有一个示例，该示例从目录中获取一个xml文件，并使用JSON.stringify()将其转换为示例.现在可以代替调用本地xml文件(foo.xml)来调用XML服务的URL，例如:

So I have NodeJS and installed the module xml2js. In the tutorial we have an example taking an xml file from directory and convert it with JSON.stringify() as in the example. Now is there a possibility instead of calling the local xml file (foo.xml), to call a url of XML service for ex: www.wunderground.com/city.ect/$data=xml

var parser = new xml2js.Parser(); 
parser.addListener('end', function(result) {
    var res = JSON.stringify(result);   
        console.log('converted'); 
}); 
fs.readFile(__dirname + '/foo.xml', function(err, data) {
    parser.parseString(data); 
});

推荐答案

您需要创建一个http请求，而不是读取文件.我想是这样的:

You need to create an http request instead of reading a file. Something like this, I think:

http.get("http://www.google.com/index.html", function(res) {
  res.on('data', function (chunk) {
    parser.parseString(chunk); 
  });
}).on('error', function(e) {
  console.log("Got error: " + e.message);
});
