Hi,
I have a document that looks like:
<root>
<a> <b> ..</b> <b> ..</b><b> ..</b><b> ..</b></a>
<a> <b> ..</b> <b> ..</b><b> ..</b><b> ..</b></a>
....
<a> <b> ..</b> <b> ..</b><b> ..</b><b> ..</b></a>
</root>
If I only want to know how many <b> elements under first <a> element , it
seems that castor needs to unmarshal the whole document and then from root
to get first A object and then get the counts of B objects from the A
object. This means a lot of other non-related objects will need to be
created before I can finally know the number of B objects under A. For
large document, it takes relative long time to unmarshal the whole
document and wastes a lot of memory to hold other objects.
As a second example, if I am interested in only the second <a> element
information, for example, it is a customer information I need to
manipulate, Castor also needs to unmarshal the whole document before I can
get to the second A object.
So I am wondering if there is some ways to unmarshal only part of the
document based on something like XPath as a argument?
Many thanks,
Risheng
