Java Web Applications

Todo Application: Persistence

The data of the application shall pe persisted as XML, for example as follows:

<users>
    <user>
        <name>alice</name>
        <password>12345</password>
        <lastTodoId>1</lastTodoId>
        <todos>
            <todo id="1">
                <title>Buy milk</title>
                <category>Home</category>
                <dueDate>2022-12-01</dueDate>
                <important>false</important>
                <completed>true</completed>
            </todo>
        </todos>
    </user>
</users>

In order that the XML data can be exchanged between different applications, the XML data should be valid with respect to XML schema todo-data.xsd.
