The usual way to compress XML is just to put it through a standard
text-compression tool such as zip/gzip. That compresses both structure
and content very effectively. But that produces binary data, which would
have to be encoded (eg base-64 encoding) before it could be wrappered in
XML, and that encoding of course adds some space overhead back in.

I don't know of any other standard way of compressing a SOAP payload.

Actually, a better answer would be to embed the XML within the SOAP
envelope, compress the whole thing, send the binary, and decompress it
before trying to interpret the message as SOAP. But I don't know whether
any of the common SOAP tools would support that.

Lots. If you're interested, websearch.

XML syntax is not intended to be terse. It's intended to be an
easily-toolable, easily-debuggable interchange format -- and has
succeeded well enough to kill off several binary interchange formats,
because in fact terseness is overrated for that set of tasks. XML has
served as a coalescence point for a whole bunch of useful technology
which was previously trapped in its own little non-interchangable corners.

If you're looking for a back-end data format, XML syntax isn't it...
though depending on your needs, the XML data model may be. See, for
example, the pureXML features in IBM's DB2 database product, which
directly express the XML Infoset -- that isn't just because XML is
trendy, it's because XML is *USEFUL* as a set of concepts.

XML is a tool. Not all tools suit all tasks. If it isn't the right tool
for your purposes, that's fine; some applications really do run in a
vaccuum and talk only to themselves, and for those XML is probably not
the right answer... unless they want the convenience of being able to
leverage other apps and existing libraries rather than reinventing some
of these wheels.
