Data Description

Consider an XML document $($WebServiceProvider$.$xml$)$:

uk$.$ac$.$le$.$cs$.$CO$3102$

Remote

java.rmi.Remote

java.rmi.RemoteException

java.net.$*$

public

account

password

url

RemoteException

MalformedURLException

boolean

private

user

void

This XML document describes a Java interface below:

package uk$.$ac$.$le$.$cs$.$C$03102$;

import java.rmi.Remote;

import java.rmi.RemoteException;

import java.net.$*$;

interface RESTInterface extends Remote$\{$

public boolean authenticateUser$($String account, String password, URL url$)$

throws RemoteException, MalformedURLException;

private void deleteUser $($String user$)$;

$\}$

Task $3$: $[30$ Marks$]$

Write a program that extracts some information from the XML above and generates the JSON output as follows. Please choose an appropriate parsing technology.

$```$

$\{$

"abstract$\_$method": $[$

"method name": "authenticateUser",

"visibility": "public",

For Task $3,$ a Java template $($WebServiceParser$.$java$)$ is provided, and you'll require xercesImpl.jar available on Blackboard. However, you can opt for alternative programming languages $($e$.$g$.,$ Python, C$++,$ C$\backslash$#$,$ JavaScript, etc.$)$ and parsers for this task. In such cases, please provide a README.txt file detailing the execution steps for your code.

It's important to note that the intentional formatting of the JSON output aims to prevent the use of pre$-$built XML to JSON functions from specific APIs. While you're free to choose parsers, the parsing technique's implementation must be in your code. For example, the program should generate the specified JSON output without including elements like "package," "import," etc. Furthermore, use of any built$-$in XML$-$to$-$JSON libraries for XML to JSON transformation $($such as "toJSONObject" in Python etc$),$ is not permitted.
