Subject DIGESTER: object creation and passing nodes to sub object
Date Mon, 05 Nov 2007 11:42:06 GMT

We want to parase a xml file into corresponding objects via digester. Here 

is our idea:

Lets say, we have a object CAR wich has several "Sub" Object, e.g. 

   |   |- TYPE 1
   |   |- TYPE 2
   |- ENGINE
   |   |- 2 LITRE
   |   |- 2.2 LITRE

We want to define a digester ruleset (XML) for each object, so that car 
has a ruleset which passes all content of element FUELTYPE to the 
digesterRuleset for the FUELTYPE object. We imagine such thing as a 
similar ruleset:

<?xml version="1.0" encoding="UTF-8"?>

  <pattern value="CAR">
    <object-create-rule classname="Car" />
    <call-method-rule pattern="abc" methodname="setABC" paramcount="0"/>
    <"WHATEVER COMES HERE ELEMENT" methodname="fromXML" 
object-name="FUELTYPE" /> 
    <"WHATEVER COMES HERE ELEMENT" methodname="fromXML" 
object-name="ENGINE" /> 

Result is a complete CAR object containing a FUELTYPE object and a ENGINE 
object. Where each Object and Subobject has its own fromXML routines 
configurable via a digester ruleset in XML.

Is this possible and if so, how?
