Adam,
1. One thing about XML is that the package your data is in (not just
packaging for me though), is much less weighty than other formats. I
cannot think of an instance where my data would still be "data" in
some other format and be smaller than if it was in XML.
2. I don't see your code reflecting the child::elemC.
<elemB><elemC>Weeeeeeee</elemC></elemB>

This one aspect has been something I've often pondered. It seems a
standard for a condensed scheme could be developed for transient
"XML"
(although it wouldn't be XML anymore). Something so the heft of the
XML
structure isn't repeated yet structure is maintained and data can
get
compressed by different means if necessary. When ready the data
could be
streamed. It seems this would greatly aid in moving large data
across
networks where the size of heavy markup in XML makes the cost
prohibitive.
Some possibilities:
1. the document/stream could be "preparsed" for structure and the
data
retrieved as it arrives (or is needed?) since it may still be in
route
further down the stream.
2. optional supported compression utilities (since the recipient
would
need to know how to uncompress).
3. optional limits on size of data to when compression is no longer
beneficial.
Quick example (not using attributes):
<document>
<elemA>Some data</elemA>
<elemB>Other data</elemB>
<elemB>More data</elemB>
<elemB><elemC>Weeeeeeee</elemC></elemB>
<elemD>binaryblahblah</elemD>
</document>
[definition]
1=document
2=elemA
3=elemB
4=elemC
5=elemD
[structure]
1>2=A 3=B 3=C 3>4=D< 5=E<
[data]
A=Some data[eod]
B=Other data[eod]
C=More data[eod]
D=Weeeeeee[eod]
E=Binaryblahblah[eod]
After typing all this, I realize it may be off topic but, I am
curious
about it.
