About
Offsite XML Design Pattern: External Assistant
This page reviews an XML design pattern that is located at an external website.

Abstract:

From the pattern: "adds outsourcing to the process of generating an HTML page from an XML document and XSL stylesheet. With a model that transforms XML data while keeping it completely separated from the processing instructions, External Assistant solves the problem of how to add external computation. Here XML data on one side and the instructions in the XSL stylesheet on the other feed a transformation process that generates output in the form of an HTML file. In this context, External Assistant explains how to call an external process whose results are incorporated to the output, always keeping high modularity and clear distinction of the responsibilities of each component."


Discussion:
