[windup-dev] JSP / JSP / Taglib Parsing & Rules

[Brad Davis]

The APIs for the Eclipse library have a DOM parser that basically extends standard DOM parsing to handle <% %> from what I could tell.

Because we leverage Eclipse for AST with Java, I wonder if we can do the same thing for JSF / JSP?  Maybe we can reach out to one of the project leads in the Eclipse community to get their recommendation on which project would provide similar functionality for those technologies.  I think Nick Sandonato from the Eclipse WTP team may be a good starting point.

Probably not XPath, because JSP can be anything, like, <%if(fish){%> 
<°)))>< <%}%>
Once I parsed JSP by looking at it as java file, and placing "out.print( 
... )" instead of the content between %> and <% . Plus special handling 
for the <%@. Didn't cover 100 % but worked for my case.

Now I would probably use the Tomcat's JSP to servlet source processor 
and parse that. WDYT? It would loose the context though.
