I was also interested in this issue and feared that EM would use DOM for 
parsing but it doesn't, but uses plain expat-like sequential parsing, so 
extracting information should not be too hard on cpu and memory.

The memory hog is the (double) de-serialisation of the extension data 
into one huge array which is not necessary because you can query the XML 
data with a simple SAX parser or using XPATH etc. That's actually the 
only reason I see for using XML at all...
