AWS Lambda函数中的XML解析

Question

是否可以在AWS Node.js Lambda函数中进行XML解析而不使用像xml2js这样的第三方模块？我想知道AWS是否具有任何内置功能,就像在AWS SDK for Node.js中一样.

Answer 1

实际上我只测试了这个,你可以直接使用xml2js开箱即用,因为......

https://github.com/aws/aws-sdk-js/blob/master/lib/xml/node_parser.js

这就是AWS JS SDK使用的内容.示例Lambda代码用于测试它,完全使用Lambda在线编辑器并针对它运行测试数据:

'use strict';

var xml2js = require('xml2js');

console.log('Loading function');

var options = {  // options passed to xml2js parser
  explicitCharkey: false, // undocumented
  trim: false,            // trim the leading/trailing whitespace from text nodes
  normalize: false,       // trim interior whitespace inside text nodes
  explicitRoot: false,    // return the root node in the resulting object?
  emptyTag: null,         // the default value for empty nodes
  explicitArray: true,    // always put child nodes in an array
  ignoreAttrs: false,     // ignore attributes, only create text nodes
  mergeAttrs: false,      // merge attributes and child elements
  validator: null         // a callable validator
};

exports.handler = (event, context, callback) => {
    var parser = new xml2js.Parser(options);
    //console.log('Received event:', JSON.stringify(event, null, 2));
    console.log('value1 =', event.key1);
    console.log('value2 =', event.key2);
    console.log('value3 =', event.key3);
    callback(null, event.key1);  // Echo back the first key value
    //callback('Something went wrong');
};

也就是说,如果你想避开这条路线,你将不得不采用标准的包装安装路线.
