问题描述

我正在尝试使用 node.js 模块 xml2js

I m trying to use the node.js module xml2js

我的代码很简单:

function testparse(pathname, callback) {
    var parser = require('xml2js').Parser(),
        util = require('util'),
        fs = require('fs'),
    fs.readFile(pathname, function (err, data) {
        parser.parseString(data, function(err, result) {
            console.log('Complete result:');
            console.log(util.inspect(result, {depth: null})); //Work
            console.log('Try to access element:');
            console.log(result.smil.body); //Work
            console.log(result.smil.body.update); //Undefined
        });
    });
}

我的xml文件如下:

<?xml version="1.0"?>
<smil>
    <head/>
    <body>
        <update /*some field*//>
        <stream name="name"/>
        <playlist /*some field*/>
            <video /*some field*//>
            <video /*some field*//>
            <video /*some field*//>
        </playlist>
    </body>
</smil>

输出给我:

Complete result:
{ smil:
    { head: [''],
      body:
        [ { update: [[Object]],
            stream: [[Object]],
            playlist: [[Object]] } ] } }
Try to access element:
[Object]
Undefined

我通过尝试成功访问了 body，但现在我卡住了，是否有模板或示例说明 xml2js 如何在某处输出解析的 xml?

I have succeed in accessing body by trying, but now I m stuck, is there a template or example of how xml2js output the parsed xml somewhere?

推荐答案

对于那些想知道 xml2js 使用和滥用数组的人

For those who are wondering, xml2js use and abuse of array

对于我的文件，树将是:

For my file, the tree would be:

.result //Object
|_.head //Array
|_.body //Array
  |_.update //Array
  | |_.$ //Object
  |   |_.fields //Strings
  |
  |_.stream //Array
  | |_.$ //Object
  |   |_.fields //Strings
  |
  |_.playlist //Array
    |_.$ //Object
      |_.fields //Strings
      |
      |_.video //Array
        |_.$ //Object
          |_.fields //Strings
