with tags a better way would be to have two tags, one that manages the data
and one that controls the ouput, so you have this
<xx:dataTag>
<xx:outputTag />
</xx:dataTag>
The data Tag returns EVAL_BODY_TAG from doAfterBody until all the 'rows'
have been consumed by the outputTag.
Why do it this way? well you could easily plug in different ouput tags for
the same data (so an unordered list, an ordered list or a table say), and
obviously have different data tags for each output.
I have some code to do this somewhere, if I get a chance (or if anybody is
interested) I'll tidy it up and post it to my web site,
