Hi Daniel,

The real question, however, is whether having one or ten characters in
the tag makes any significant difference in the current parsing
process, which quite frankly I have no idea about and would need to be
measured before it's overly debated, if you want my opinion.
Measuring is always a good idea. I did some measurements (calculated the
size savings from using smaller tags and compared them to the speed of
an IDE drive) and concluded that the probable savings were negligible.
Well, there is a significant difference in uncompressed size.
Take a look at Tools-Options-Load/Save-General. There is an option
'optimize XML for size'. This option defaults to 'optimize' and iirc it
was introduced in an early effort to make the file load process faster.
I would even assume that actual profiling led to this idea.
All this does is eliminate sequences of blanks or tabs and newlines
which are needed to pretty-print the XML so it is readable for humas in
an ordinary text editor, leaving one huge unstructured line of XML. I'd
assume that the effect of this on compressed size is limited, but
certainly does affect uncompressed size.
This suggests that uncompressed XML size does have a measurable effect.
And that also suggests a more relvant experiment than stopping at byte
counts and speculating whether or not they have a significant effect:
Take the same (big) document saved with and without pretty-printing,
compare their sizes and measuring the load times. Depending on details
of the parser used, the same change in uncompressed size due to tag
lengths could have a slightly larger effect than pure whitespace,
because tags go through somewhat more processing (e.g. token lookups).
Ciao, Joerg
