Hello,
A word of introduction... I belonged to the list a year or so back,
but got sidetracked from Cocoon for awhile. Now I'm back tinkering
with 2.04, and have no shortage of questions.
Here's one (a rather broad and newbie-ish one.) In my project I have
a large number of XML files that correspond to time series. Each is
the same format:
<timeSeries>
<seriesName>P12345</seriesName>
<observation>
<date>2001-03-12</date>
<value>1.25</value>
<date>2001-03-13</date>
<value>1.28</value>
</observation>
</timeSeries>
... etc.
Now: using the various mechanisms available through Cocoon, how best
would I "query" a given file (directly, as opposed to through a
database) via an HTML form, e.g., to extract and display only
selected dates/values?
I have a vague grasp of various ways I could do this if my data were
to reside in an intermediate DBMS of some sort, but the objective
here is to store each time series as an XML source file only, while
still being able to query it.
Does this make any sense? :)
