Strange output??

Question

Hello,
I am using the SAX parser to parse a xml file which can be downloaded from the http://archive.godatabase.org/latest-termdb/go_daily-termdb.obo-xml.gz.
The file is a gene ontology. My problem is that from the 25000 terms described in this file, the parser can not read the id node of 100 of these terms correctly. The output should be like
GO:0000142
while it reads it as
GO:00001
42
as a result what I have as the terms id is 42 . As I said this only occurs randomly in 100 terms from the 25000 terms. The characters function doesn't do anything at all
public void characters(char[] ch, int start, int length) throws SAXException {
          tempVal = new String(ch,start,length);
     }just reads the values. Any ideas??

Thanks for letting me know what was wrong. The thing is that it's so easy to fix too. just use a stringbuffer instead of the string . so the character method will look like this.
public void characters(char[] ch, int start, int length) throws SAXException {
                sBuff.append(ch,start,length);                
     }And tou can reset the stringBuffer at the startElement method
public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException {
               //reset the stringBuffer
            sBuff.setLength(0);     
                     }    Thanks again
