Dear Sir or Madam,
I will make a persitence layer which is independant from my data
storemedium.
Now my question : Is it possible to make a OQL-Statement for a XML-File
similiar
you can do it with JDO ?
I want to show my question clearly in a short example :
Ex1. Actor.xml
-------------------
<?xml version="1.0" encoding="UTF-8"?>
<actors>
<actor personal-iD="100">
<address>
<city>munich</city>
<street>kornstr. 24</street>
</address>
<last-name>Schmidt</last-name>
<first-name>Hans</first-name>
<tel-number>040/123458</tel-number>
</actor>
<actor personal-iD="101">
<last-name>Fleisch</last-name><
first-name>Stefan</first-name>
<tel-number>024/252525</tel-number>
</actor>
</actors>
In a Database the hole thing will looks like this :
Ex2. Table Actor
---------------------
personal-ID lastName firstName ....
100 � Schmidt Hans ....
200 Fleisch Stefan ....
Now I want to get the actor with the personal-ID 200. If my data were
stored in a database (Ex2) I can say :
oql = db.getOQLQuery( "SELECT ... WHERE personal-ID = 200 );
and get only the actor with the ID 200. Can I get the record similar by
unmarshalling the Actor.xml in Example 1 ?
I think the Castor XML API is strictly seperated from the Castor JDO
API,
but I also think that I'm not the only one who want unmarshalling only a
few
objects from a XML-File and want to change them.
Is there a solution for my problem in the castor api, or haven't I the
possibility
to make a OQL-Statement to a XML data storemedium ?
Best regards
Chris
