JXPath 1.2 - get objects by class

[P....@pilz.ie]

Hi,

Just wondering if it is possible to retrieve all objects of a specific 
class from an object tree including if they are contained somewhere in the 
list.
 
Will this work

Iterator iterator = context.iterate("//com.mycompany.MyObject.new()");

Thanks.

Parvez,

Try this variant:

//*[@class/name='com.mycompany.MyObject']

Previous variant just checked if there was such objects. This variant should
select them.

Thanks Scott.

I tried both ways but doesn't seem to work. It does return Iterator with 
one object of Boolean with false value.
Though if I give an invalid class name then it does throw an error that 
class not found.

Any suggestions?

Thanks.

.new() will instantiate one instance.  Try using getClass() as a
pseudo property (the introspector treats this as a read-only property.
 Something along these lines:

Iterator iterator =
context.iterate("//@class=java.lang.Class.forName('com.mycompany.MyObject')");

You may even be able to get away with
"//@class/name='com.mycompany.MyObject'".

Hope this helps,
