XML : using JAXB for multiple sets of XML messages in same file

In my above question "message" means "<organization> .... </organization>" in below given sample XML.

Consider I am having input XML file with following content

  <organization>      <director>          <fname>Dan</fname>          <lname>Schman</lname>      </director>  </organization>    <organization>      <director>          <fname>fan</fname>          <lname>Heman</lname>      </director>  </organization>  <organization>      <director>          <fname>Ban</fname>          <lname>Sheman</lname>      </director>  </organization>        

is it possible for me to use JAXB for unmarshaling such input XML ? Or is there any better tool which can be used to achieve this ?

I am familiar with using JAXB from a file having single message only (ex. any configuration file). But how do I go about when input file has multiple messages as given above?
