[Digester] Help please
Could you please help me on the following problem?
If I have an xml file containing the following element:
...
<author name="....">
<address> ... </address>
</author>
....
and I have the following class defined for author element:
public class Author{
private string name;
private string address;
public setName(name){
name=this.name;
}
public getName(){
return this.name;
}
public setAddress(addr){
this.address=addr;
}
public getAddress(){
return this.address;
}
}
how do I say digester parser to set the "name" property of the stack top
object equal to the value of the "name" attribute of the author element.
I have tried:
addSetProperty(*/author, "name", "name");
but it doesn?t work. Is this the right rule?
Thanks in advance,
Aristos

There are some errors of sintaxis in the example, but the more relevant
inconsistence is
public setName(name){
name=this.name;
}
It must be
public setName(String name){
this.name=name;
}

If you, Aristos, look at the example file
`jakarta-commons/digester/src/examples/api/catalog/CatalogDigester.java'
in the CVS repository, you will get the idea behind addSetProperty.
Comments in that example source code say:
// Each tag of form "<attr id="foo" value="bar"/> needs to map
// to a call to setFoo("bar").
And also this:
// Note that despite the name similarity, there is no link
// between SetPropertyRule and SetPropertiesRule.
Cheers,
Adrian P.J.

No, it's not the right rule to use for this.
You can use the SetPropertiesRule, which tries to map all xml attributes
to matching set methods on the top object:
digester.addSetProperties("*/author");
Or you can use the CallMethodRule:
digester.addCallMethod("*/author", "setName", 1);
digester.addCallParam("*/author", 0, "name");

Simon
