I needed to add some on-the-fly lookups for data stored in XML databases without having them gobbling up memory. Most games of this type had a vehicle and weapon database, usually with a rotating 3D model or picture of the object. Using the TxmlTextReader function with a cache works fine. Only need to do the lookup once when examining an object.

All weapons come with suitable entries by entering the ground crew mode from proximity to any Apache helicopter. We can re-use this for tutorial pop-ups, optionally adding a tag to the XML entry that points to an audio file thus triggering playback. If that makes any sense.

I mention it here as it just occurred to me and don't want to forget it.
