I have written the following source code to read out from a XML file; and actualle line which are between <Line> </LINE> .
The problem is when there are more than one line of <Line> </LINE> . in sequence I get just the first one, why!?

<LINE>Horatio says 'tis but our fantasy,</LINE>
<LINE>That if again this apparition come,</LINE>
<LINE>He may approve our eyes and speak to it.</LINE>

Second problem that I'm facing is when I try to use the hash map to count the occurrences of the words, I get an error message for the command:
anInteger = new Integer(Integer.parseInt(anInteger + 1));

//"The operato + is undefined for the argument type Integer, int"
