I handled this by setting up a StringBuffer and appending to it, using a boolean
switch on when processing the particular tag in startElement(), switch off when
done in endElement().

Thanks
After I posted my problem I found a reference that told me about this
behavior. (This is my first time using SAX).
Again
Thanks for your quick reply.

The SAX spec says that a parser is free to report the text in a given
element in a single call to characters, or in multiple calls, if that
better suits the implementation. The handler is responsible for
collecting the data together into a single string. The way I normally do
this is by creating a StringBuffer in the startElement method, appending
each chunk of characters to the buffer (it has an append(char[], start,
length) method which makes this very easy), and call toString on the
buffer in the endElement method.
