 All, I am new at using variable/parameters and am trying to loop through a result tree fragment and dynamically set some variables to the values of the result tree fragment, and call a template that process these variables/parameters. The variables represent names of nodes within the XMSL document whose values I need to access. I need to compare a user's old choice to their new choice and compare the results and output them based on how they compare. I want to re-use this template for many different types of inputs. I just found out that XSLT does not support result tree fragments. My project is using the Xalan processor (I have no influence to suggest another process). Can someone tell me the exact syntax of how to invoke the proper extension? Also since I am inexperienced with this, I suspect that there are errors in my stylesheet. If someone can take a look at the following code snippet, and make corrections, I would appreciate it.
