SAX Parser returns same element two times with 2nd time as empty

My Sax parser is doing weird thing when I am trying to parse simple xml file,

This is my xml file,

<?xml version="1.0"?>
<organization>
                <employee>
                                <title>Harry0</title>
                                <link>Smith0</link>
                                <date>hs0</date>
                                <salary>200000-0</salary>
                </employee>

                <employee>
                                <title>Harry1</title>
                                <link>Smith1</link>
                                <date>hs1</date>
                                <salary>300000-1</salary>
                </employee>

                 <employee>
                                <title>Harry2</title>
                                <link>Smith2</link>
                                <date>hs2</date>
                                <salary>300000-2</salary>
                </employee>
</organization>

Now If I want to read only the title element,

String elementValue = null;
String localName = null;
@Override
public void startElement(String uri, String localName, String qName,
        Attributes attributes) throws SAXException {
            this.localName = localName;
}


@Override
public void characters(char[] ch, int start, int length)
        throws SAXException {
        elementValue = new String(ch, start, length);
        if (localName.equals("title")){
            Log.e(localName,elementValue);
        }

}

and the output is,

10-19 14:41:02.261: E/title(7754): Harry0
10-19 14:41:02.261: E/title(7754):                                 
10-19 14:41:02.281: E/title(7754): Harry1
10-19 14:41:02.297: E/title(7754):                                 
10-19 14:41:02.297: E/title(7754): Harry2
10-19 14:41:02.297: E/title(7754):   

The tag name for the empty lines as well as the title line is same, i.e. title

Why Sax Parser is returning everything twice ?
