As XML has become a popular format for information exchange, the efficient processing 
of broadcast XML data on a constrained device (for example, a cell phone or a PDA) 
becomes a critical task. In this paper we present the EXPedite system: a new model of 
data processing, which  migrates  the power of the data-sending server to receivers 
for efficient processing. It consists of a general encoding scheme for servers, and 
streaming query processing algorithms on encoded XML stream for client devices. 
Preliminary experiments show the impressive performance of the EXPedite system.
