Is XSLT using JAXP recommended for real time enviroment
We have an HTML page which user will use to get information. At the click of submit information is queried from 2 systems which is in XML format. This information is then merged into one before sending it back to the client.
Couple of questions:
1. My question, is it advisable to use XSLT for such kind of real time environment. I am not sure of the performance, if it's going to overload CPU, memory etc.
2. What are the basic guidelines for writing efficient XSLT transformation.
3. Is merging using XSLT slower than directly doing it in JAXB?
