it's only going to take a lot of memory to parse the XML if you load the entire XML DOM into memory. if you parse it with SAX, there's no issue. you can stream it directly from the network and parse on the fly. http://en.wikipedia.org/wiki/Simple_API_for_XML

regardless, having it on the SD card makes no difference. you still need to parse it the same. the only difference is if you start with a stream from a file or a stream from the network. your parsing code is going to look exactly the same.

you might want to question whoever gave you that requirement. it sounds like either you misunderstood them / didn't get enough information or they are themselves confused.
