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
