Convert XML files to a classes that elements are annotated and behave like previous XML elements

I have a problem with converting xml files to annotated classes that elements are annotated and will render by reflection. Into a legacy system, there is numerous XML files that engine of system load them and after unmarshling them, loaded them into objects. I want to eliminate this XML file from my system and replaced them with OOP methodology (like converting one XML to a annotated Java class that all of it elements and values can develop by annotation). There is an example of my XML file:

<?xml version="1.0"?>

<?xml-stylesheet type="text/xsl" href="state_xslt.xsl"?>
<sequence-mapping xmlns="http://rada.com/rsgrammar.xsd">
    <sequence id="load-current-darams">
        <starter>
            <extender id="loadCom"/>
        </starter>
        <lastNode>
            <startPage forward="/jsps/current-music-info.jsp">
                <outer-to-inner>
                    <put object="dots" to="dots"/>
                    <put object="theds" to="theds"/>
                </outer-to-inner>
            </startPage>
        </lastNode>
    </sequence>
</sequence-mapping>

Then, I want to write this XML by Java class that represents fields and values. Any help?
