Hello,
I have some questions concerning documents.
1. How can merge two documents, if both documents have elements with the
same name
on the same level?
Is there a possibility to avoid the IllegalAddException ?
Is there some kind of automatism?
2. I have an document created with
document = IndexedDocumentFactory.getInstance().createDocument();
then I append some elements and after this I want to search for nodes:
List list = document.selectNodes( "//test/testelement" );
I always get a the follwing Exception:
java.lang.NullPointerException

...........
and I don't know what could be wrong, because the errormessage is not
really helping ....
Could anyone help me?
Thank you in advance
