Nina:
I didn't see a reply to your post. I'm relatively new to Cocoon but
can relate to your question and was considering this tonight.
Yes, if you're new to this environment it's going to be intimidating to
figure this out since yes, it's straightforward to do ith with a
relational db and servlet (I've done this).
Most of the experts on this board will probably tell you it's easy to
do this in Cocoon but of course they know how to do it. What they mean
is it can be done with a few lines of code! There's a difference
between easy and short.
Technically, I believe the answer entails a pipeline that scours the
directory for the file names, converting these to XML; next step in the
pipeline scours each file and extracts JUST the street element; next
step does the searching. That's the highlevel approach. You'll have
to spend a couple of hours learning what a pipeline is and matchers.
If you have thousands of files then for performance reasons you'd
probably want to batch (daily, hourly, whatever depending upon the
currency you need) the process of the first two steps above, and put
the results into a file that would look like this:
<mydocs>
<file name="foo1.xml" street="elm"/>
<file name="foo2.xml" street="maple"/>
...
</mydocs>
then you would only have to search this file each time.
This is just my thinking, from limited experience, but thought I'd put
my two cents in. Like most things in Cocoon, seems there are numerous
solutions to each problem.
(I would have posted this to get others' feedback but I'm in the midst
of moving my list subscription to another email address so it was
difficult to do that.)
