Not by any means a stupid question, but a frequently asked (and not definitively
answered) question. There are two issues - compression of XML to remove the
"bloat" and saving a parsed data structure in binary form to reduce the overhead
The first issue is definitely one best handled by compression, but whether
a generic compression such as gzip or a compression scheme that exploits the
specific regularity of XML is still debated. Well, at least for wireless
devices one can make a credible case that an XML-specific compression scheme is
more efficient of the various limited resources on a wireless device. In general,
though, you would be well-advised to not try to compress arbitrary text better
than gzip can. You'll fail.
The binary XML issue comes up every few months and generates a lot of dispute.
The "mainstream" position seems to be that XML is really not all
that hard to parse, the parsers are well-optimized, the overhead of doing the
byte swapping and other binary format conversion to transfer parsed data from
one platform to another outweighs any theoretical advantage of having a
"compiled" form, and that the whole issue is a red herring. I expect that
the holders of the minority view (Hi, Al!) will let you know their response.
