[DIGESTER] Newbie question
Hi all,
I've a simple problem, and I cant manage to resolve it, what are the
digester rules for the follwing reccurent pattern :
<ressource type="page" id="item.entite">
<locator type="label" value="zobilamouche"/>
<ressource type="form" id="formID">
<locator type="name" value="entityForm"/>
</ressource>
</ressource>
I've added the following methods to the Ressouce class :
addRessource(Ressource re) and setParent(Ressource re)
Thank you for your precious help.
Richard

Yep, addSetNext() is what I really meant :-). Your code looks good to go.

Thank you, Craig.
I dont know the "addCallNext" method you told about, but I think I have the
solution (?)
UIResource ui,tmp=new UIResourceImpl();
Digester d = new Digester();
d.setValidating(false);
d.push(tmp);
d.addObjectCreate("*/resource", UIResourceImpl.class);
d.addSetProperties("*/resource");
d.addObjectCreate("*/locator",UIResourceLocatorImpl.class);
d.addSetProperties("*/locator");
d.addSetNext("*/locator","setLocator");
d.addSetNext("*/resource","addResource");
try
{
d.parse(fileName);
}
catch(Exception e)
{
log.error("Unable to parse the xml file "+fileName,e);
}
ui=(UIResource)tmp.getChildren().iterator().next();
ui.setParent(null);

You can use patterns like "*/ressource" and "*/locator" to match those
elements, no matter how deeply they are nested. So, you might have
rules like this:
digester.addObjectCreate("*/ressource", "com.mycompany.Ressource");
digester.addSetProperties("*/ressource");
digester.addCallNext("*/ressource", "com.mycompany.Ressource");
(I would have the call to setParent() happen inside the addRessource()
method, instead of requiring both to be done by Digester rules).
Because these rules will be fired for even the outermost <ressource>
element, you'll want to push a Ressource object onto the digester stack
before you start parsing.

PS: If "ressource" is supposed to be in English, it's actually spelled
"resource".

You can use patterns like "*/ressource" and "*/locator" to match those
elements, no matter how deeply they are nested. So, you might have
rules like this:
digester.addObjectCreate("*/ressource", "com.mycompany.Ressource");
digester.addSetProperties("*/ressource");
digester.addCallNext("*/ressource", "com.mycompany.Ressource");
(I would have the call to setParent() happen inside the addRessource()
method, instead of requiring both to be done by Digester rules).
Because these rules will be fired for even the outermost <ressource>
element, you'll want to push a Ressource object onto the digester stack
before you start parsing.
