Do you mean the paper "An Adaptive, Fast and Safe XML Parser Based on
Byte Sequences Memorization" (http://www2005.org/cdrom/docs/p692.pdf)
by Toshiro Takase and others that was at the WWW conference last year?
Their parser caches the SAX events generated from a sequence of bytes
and then replays those events when encountering the same bytes (of
course taking into account context like prefix mappings).  They report
speedups of up to 70% compared to Piccolo.
