The task is to create an AWS Lambda function written in Javascript, that receives an XML file representing a message between two people. And generates a new XML file with the sender and recipient names swapped. We would like you to invoke this AWS Lambda function from a node.js application which is designed to monitor and create files on the local filesystem. You will therefore need to develop two seperate pieces of software: 1. A node.js app that reads data from a file, and communicates to AWS Lambda 2. An AWS Lambda function that processes and parses XML data. AWS Lambda function Your AWS Lambda function will take a message, and generate a response message. To do this, it should do the following: ● Take XML data as input. ● Parse this XML file, looking for the XML nodes “from” and “to”, which are child nodes of the XML node “message”. ● Read the value of these two nodes, and swap them around (so the value of “from” becomes the value of “to” and vice-versa). ● Return this new XML data. Please do consider how you might validate the data and handle error cases. An example of the XML data is provided in the next section. Node.js app You should create a very simple Node.js app which reads an XML file from the local machine. This file can be called “[login to view URL]” and should contain the following: <?xml version="1.0" encoding="UTF-8"?> <message> <to>Chirag</to> <from>Jay</from> <body>How are you?</body> </message> This node.js application should do the following: ● Detect when an XML file has been added or updated within a specific folder in the local filesystem ● Read the XML from the local filesystem ● Submit the XML data to your AWS Lambda function ● Save the response XML data into a new file You should expect the new XML file to look as follows: <?xml version="1.0" encoding="UTF-8"?> <message> <to>Jay</to> <from>Chiragf</from> <body>How are you?</body> </message> Please note the node.js application is not intended to operate as a REST server (using express, etc.), it simply needs to run constantly and monitor the presence of a new XML file, processing any new file found.

We already have the two components required for this project - 1) monitor S3 bucket for a new file and invoke Lambda function, 2) Javascript code to swap two elements of XML. We are AWS Registered Partner. This solution has been designed by 15+ years experienced Senior Architect. Details: We already have a function that monitors S3 bucket and triggers a Lambda function when a new file is added. This is a Lambda (Serverless) function so there is no cost unless you put a new file. We also have a Javascript code to change value of one element of XML to another element of XML. We will merge the two solutions and place this modified XML into a new bucket. It will be a continuous process - detect new file in S3, modify the XML and place in new S3 bucket, place errors in Cloudwatch. We will be happy to show the two pieces before you award project. Pay only after you are happy with code. We have 100% positive review. This Solution has been designed by our Senior Architect (15+ years experience). About us: We are from VisionFirst Technologies Pvt. Ltd. We are AWS Registered Partners. We have developed and implemented large apps (multiple mobile apps, webapps and custom softwares) with a few apps having 5000+ users.
