Dear All,
First time posting on this list - please excuse any duplication - have
looked through archive, cookbook, FAQ etc.
I am currently putting a system together which reads a large(ish) XML
document
from a database containing daily results from another of my
applications.
The data in each days document does not change too much - if it does I
can
detect it - so I decided to cache the dom4j Document (I'm using Tomcat).
Different users should get different views using XSLT (also compiled &
cached)
against the "master" Document.
Essentially, my question is how to best pre-filter the master Document
for different
users.
For example - a reduced view of my Document could be...
------------------------------------------------------
<All CloseDate="20031128">
<Zone Name="Global::CB">
<Strategy Name="GL-CB-0001" DisplayClass="1">
...
<Strategy Name="...">
<Strategy Name="...">
<Strategy Name="...">
<Strategy Name="...">
</Zone>
<Zone Name="Japan::CB">
<Strategy Name="JP-CB-0001" DisplayClass="1">
...
<Strategy Name="...">
<Strategy Name="...">
<Strategy Name="...">
<Strategy Name="...">
</Zone>
<Zone Name="NonJapan::CB">
<Strategy Name="JP-CB-0001" DisplayClass="1">
...
<Strategy Name="...">
<Strategy Name="...">
<Strategy Name="...">
<Strategy Name="...">
</Zone>
...
etc
...
</All>
------------------------------------------------------
User A : might want Zones "Global::CB" & "Japan::CB"
User B : might want the entire data set
User C : might want just "NonJapan::CB"
I could try to support this at the XSLT level but I'm wondering whether
to
do it at the dom4j level by returning a new "sub-Document" from the
master.
The trade off being the Document creation Vs. XSLT complexity.
Is there a "best" way to do this sort of thing?
Should I be dropping down to SAX/filters etc?
Any wisdom on this very much appreciated.
Best regards
Chris
