Well, here is what I am dealing with, The XML file is actually an XML- defines SVG file that represents a vector drawing. It is a requirement that the files remain in SVG, as the user will be loading and unloading these files on and off of the device, editing and viewing them with my app. So we are stuck with SVG/XML as the data source and destination (I have conversion performance issue on both sides of this equation, both from String -> float coming in, and from float -> String going back out).
A mapping from String <-> float would be a really novel solution here, just trying to figure out now how to implement it. In answer to some of your other questions, no, I have to read the entire XML file in at 'load' time (as the user needs to see all of their drawing). I'm not sure about the need for a timestamp in this case, wouldn't any mappings created be, essentially, permanent? If I create a mapping in a volitile data structure that is created at run-time, I'll need to seed it somehow, either with entries as they are read, or create some 'smart' routine that does this work in the background. Just thinking out loud here, thanks for any input.
