not well-formed ( Invallid token) in Android?

Question

I'm trying to read the xml file via XMLParser in Android.But at runtime I'm getting the some errors and warning oforg.apache.harmony.xml.ExpatReader.parse(ExpatReader.java:318) at org.apache.harmony.xml.ExpatReader.parse(ExpatReader.java:275) and com.test.SAXXMLParser.parse(SAXXMLParser.java:34)

Here is my XM:L File content

Here is my XMLParser code

public class SAXXMLParser
{

    public SAXXMLParser()
    {
    }

    public static Vector parse(InputStream inputstream) throws SAXException, ParserConfigurationException, IOException
    {
        Vector vector1;
        XMLReader xmlreader = SAXParserFactory.newInstance().newSAXParser().getXMLReader();
        SAXXMLHandler saxxmlhandler = new SAXXMLHandler();
        xmlreader.setContentHandler(saxxmlhandler);

        xmlreader.parse(new InputSource(inputstream));
        vector1 = saxxmlhandler.getDatabase();
        Vector vector = vector1;

        System.out.println((new StringBuilder("Vectore Length:::::::")).append(vector.size()).toString());
        Test_Demo.Vectore_mquestionDatabaseStructure = vector;
        return vector;
     }
}

Log cat shows the error at line = xmlreader.parse(new InputSource(inputstream)); Can someone help me how to solve this.

The error is because .. {drum roll} .. it is not valid XML. This can be trivially tested in by XML validation, without needing for the Android application to abort itself.

Trivially, it cannot possibly well-formed because it contains a bare < and > tokens in it. XML does not support CDATA magically, unlike SCRIPT elements in HTML.

Either apply XML-entity escaping or use CDATA section. A proper XML editor would also help with correct encoding.

not well-formed ( Invallid token) in Android?
