Thanks Binu

The code is now running. it is giving values again null

xml is 
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE WEATHER SYSTEM "Weather.dtd">
<WEATHER>
  <CITY NAME="New York">
    <TEMP>64
  </CITY>
</WEATHER>

dtd is 
<!ELEMENT WEATHER (CITY)+>
<!ELEMENT CITY (TEMP)>
<!ATTLIST CITY NAME CDATA #REQUIRED>
<!ELEMENT TEMP (#PCDATA)>  

code is
