XML Schema, XSLT and XML Parsing

Data Description

Consider an XML document (IServiceREST.xml):

<xml version="1.0" encoding="UTF-8">

<service id="IServiceREST">

<inherit>

<parent>Remote</parent>

</inherit>

<package>uk.ac.le.cs.module</package>

<include>java.rmi.Remote</include>

<include>java.net.*</include>

<include>java.io.*</include>

<abstract_method id="getContent">

<visibility>public</visibility>

<parameters>

<argument type="URL">url</argument>

<argument type="int">timeout</argument>

</parameters>

<throw>

<exception>MalformedURLException</exception>

<exception>IOException</exception>

</throw>

<return>String</return>

</abstract_method>

<abstract_method id="deleteUser">

<visibility>public</visibility>

<parameters>

<argument type="String">username</argument>

</parameters>

<return>void</return>

</abstract_method>

</service>

This XML document provides an alternative representation of a Java interface below:

Tasks:

Task 1: [35 Marks]

Write an XML Schema (IServiceREST.xsd) that allows validation of the provided XML document.

Note that the schema must be consistent with these rules in Java:

An interface may extend one or many interfaces.

There can be only one package statement

There can be zero to many import statements

An interface can have zero to many abstract methods

A method only allows one value to be returned

A method can only have zero or one visibility modifier *

A method can accept zero to many arguments

Exception(s) may be thrown from a method

*If a method has no visibility modifier then it is accessible only within its own package (default

visibility); assuming all methods are non-static.

Task 2: [30 Marks]

Write an XSLT stylesheet (IServiceREST.xslt) that takes the provided XML document as input and

generates an HTML document as follows:

(Note: You may show the result in a different page layout or colour scheme. The page must display

the name, return type and the parameter list of each method)

Task 3: [35 Marks]

Write a Java program that reads the XML above and produces an output as follows. Please choose

an appropriate parsing technology (DOM/SAX).

(Note: You need to implement either XMLParserDOM.java or XMLParserSAX.java)

Submission

Zip all files in a single zip file for submission.

oIServiceREST.xsd

oIServiceREST.xslt

oXMLParserDOM.java (or XMLParserSAX.java, depending on your choice)

The archive should be named CO3098_CW1_email_id.zip or CO7098_CW1_email_id.zip

(e.g. CO3098_CW1_yh37.zip).

Your submission should also include a completed coursework plagiarism coversheet (print and signed PDF or image). You need to submit the zip file via Blackboard and you are allowed to re- submit as many times as you like before the deadline. Marks for any coursework which does not have the accompanying cover sheet will be withheld till you provide one.

Note: apart from the XML document above, we might use other XML instance documents as the test suite for assessing task 1, 2 and 3. Your schema and the XPATH used in your XSLT should also work for these XML documents)
