Michael and Michael,

Thanks for your help.  With your advice, I was able to solve my problem.  I just wish this was all mentioned in the
documentation (the API docs listed on their website don't have any of this information).

Thanks again,
- Mark

Sa x parser


There is no reason why any text should be getting cut off. However, it is
important to remember that the parser is free to break up the text content
into chunks, and it may very well be that for implementation reasons, the
parser is providing the text before and after the entity reference in
separate calls to your ContentHandler's "characters" method. So make sure
you have not coded with the assumption that a call to "characters" is giving
you the entire content of that element.

The typical pattern to use, here, is to maintain an internal StringBuffer,
keep appending characters received in calls to "characters" until you get an
"endElement" call. Only when you get the "endElement" call should you
process the string and clear the buffer.
