Hi.

As well as the start and end handlers for a pair of tags, you need to
specify a char handler for the text (data ?) in between tags.

Presumably, your start handler would have tracked the fact that you
are in the "chain"

...<head><ut>

at the point that the char handler returns the string "F" to your
application. You then extract the string with the char handler and,
because you've kept track of where you are, you store it wherever it
should go.

The examples in the Expat source tarball detail this. The docs make it
even clearer as you get to see just how many handlers there are !
