jaxb bindingx.xml “results in too many target nodes”

Question

I\'m trying to make just one adapter for every type of element, so I created a bindings.xml file:

<         


        

Answer 1

Try to add multiple="true" attribute:

<jxb:bindings multiple="true" node="//xs:attribute[@type='Id']"

Answer 2

I end up with a similar problem "too many target nodes(3)" however could not find any answer on any of the sites...Posting the solution which I found after lots of trail and error...Basic idea to solve "too many target nodes(3)" is to give complete XPATH of the node which is multiple in your XSD.

Below is my XSD:
