For practical purposes, I don't think you'll gain much using plugins
for c:set and c:out, since they are relatively simple, and the
overheads for invoking the corresponding tag handlers is relatively
minor. You'll probably achieve most benefit if you can provide plugins
for them that only handle tags with no or empty bodies.
If you must, just for academic discussion, you can get to the body
content of a tag by generating codes to invoke pushBody() when you
enter the body, and popBody() when you leave.

Thanks a lot at first :-)
By now I think on two occasions the body content should be used. Firstly in
the out tag, because some special characters should be converted, so if body
content is output, the body content should be filtered. Secondly in the set
tag, if the body content is assigned to the variable, the body content should
be got at first.
That's why I think there should be a method to get the body content.
Now in the out tag, I just output the body content without filter. In the set
tag, when I have to use the body content, I invoke the method
dontUseTagPlugin. I don't know whether doing so is ok.
