Java Integration

 

For this exercise, we will use the base code of my previous exercise. Here is the link

Let us update the XML file and add some errors. I have updated the third record Item element as wrongitem. 

 

<?xml version="1.0" ?>

<items>

    <item id="1">

        <name>iPhone 5</name>

        <manufacturer>Apple Inc</manufacturer>

        <price>600</price>

    </item>

        <item id="2">

        <name>iPhone 6</name>

        <manufacturer>Apple Inc</manufacturer>

        <price>700</price>

    </item>

    <item id="3">

        <name>Moto X</name>

        <manufacturer>Motorola</manufacturer>

        <price>200</price>

    </wrongitem>    

    <item id="4">

        <name>Moto G</name>

        <manufacturer>Motorola</manufacturer>

        <price>450</price>

    </item>    

    <item id="5">

        <name>Samsung S4</name>

        <manufacturer>Samsung Corp</manufacturer>

        <price>550</price>

    </item>    

</items>

 

 

Now let us override three more methods. 

 

    @Override

    public void warning(SAXParseException e) throws SAXException {

        System.out.println("Warning");

    }

    @Override

    public void error(SAXParseException e) throws SAXException {

        System.out.println("Error");

    }

    @Override

    public void fatalError(SAXParseException e) throws SAXException {

        System.out.println("Fatal");

    }

 

 

Also in the readDatafromXML() method, we will remove throws SAXException and place the below code. 

 

 

 

try {

SAXParser parser = factory.newSAXParser();

parser.parse(new File(filename), this);

} catch (SAXException e) {

System.out.println(e.getMessage());

}

 

Now let us look at the output. 

 

 

Fatal

The element type "item" must be terminated by the matching end-tag "</item>".
