The ApacheJSSI - Package is based on a general PageParserServlet
which allows you to define 'TagHandlers' which can be registered in the
init-function of the Servlet. The one predefined tag which is handled is
the <SERVLET>-Tag (and the <A>, <FRAME>,<AREA> - tag in an URL-rewriting
SSI).
The PageParserServlet parses the page once, creates the TagHandlers and
caches the positon information. In the processing stage of the page, the
'executeTag()' - method of the TagHandlers is called (The <SERVLET>-tag
handler just calles the servlet with the parameters got in the parsing
stage).
See the Api-Documentation of ApacheJSSI, it contains a simple example how
to implement the TagHandler interface.
The parsing process does _not_ generate a DOM tree or whatever, it is just
plain tag-driven and fast. But if this is sufficient for you, it might be
worth checking it out. What exactly do you want to do ?
ciao,

If Microsoft is the answer, it must have been a VERY silly question.
