I just want to have a sense of what is going on. Well, i have some more questions for you. Currently, i'm working on a project that selects nodes on an encoded XML file using XPath to query. However, i just want to implement only a small subset of XPath. I'm thinking of two strategies at the moment. 1. I use the full Jaxen and only implement small and necessary methods in the DocumentNavigator interface (am i right here?) 2. OR implement a small subset of XPath based on Jaxen and integrate tightly with methods to traverse axes on an encoded XML stream. What do you think of these two strategies?
