I have a xml dictionary file with about 95000 entries, 20
Megabytes in
size. Due to its nature I need to do searching amongst different
criterias (languages, substring matching, ...) and I intend
to use XSL
for it.
Now - judging from my latest experiments - I wonder if
xml/xsl is a good
choice for implementing such a thing, since - given my present
understanding of xml/xsl - each time I invoke the
xsl(t)-processor the
file is read (flatly) again.
No, every XSLT processor has an API that allows you to build the tree
once, in memory, and then do multiple transformations on it (using
different stylesheets, or using the same stylesheet with different
parameters).
However, if you can't keep the data in memory between the different
searches, then an XML database would probably be a good solution. Take a
look at Software AG's Tamino.

And since this file is so big I
wonder if
this is efficient? I also thought about generating separate,
smaller xml
files which hold additional statistical data that I could preprocess
with another stylesheet in order to save some time, but I am
not sure if
this would be useful.
What do you know about this?
Probably many of you work with much larger databases, so what
would you
do? An online reference would also be fine :-)
I also tried to get some speed results on the various
xslt-processors,
but the latest I found was done by www.xml.com somewhere back
in 2001,
and I believe that there have been many changes - and
improvements - to
the various xsl(t)-processors. Do you know of any more recent
tests? So
far I have only tried the msxml and saxon, favouring the latter since
it's platform independent due to its Java nature.
If someone could enlighten me on that, it would be very nice :-) I am
more experienced using SQL with databases such as db2, and hence I
apologize that some of my questions may sound somewhat
awkward and strange.
Greetings and thanks in advance,
