XStream Custom转换器

Question

我有这个Xml：

<INDIVIDUO>
    <NOME>Some Name</NOME>
    <CPFCNPJ>xxx.xxx.xxx-xx</CPFCNPJ>
    <IMOVEIS>
        <MATRICULA>1511</MATRICULA>
        <MATRICULA>1512</MATRICULA>
        <MATRICULA>1680</MATRICULA>
        <MATRICULA>4698</MATRICULA>
    </IMOVEIS>
</INDIVIDUO>

我有这个班：

publc Class Imoveis {
   String matricula;
}

所以我想把它转换成我的班级Imoveis列表。

******更新*****

这是我的洞xml：

    <REGISTRO>
        <CANCELAMENTODEINDISPONIBILIDADE>3123123</CANCELAMENTODEINDISPONIBILIDADE>
        <CANCELAMENTO_TIPO>2</CANCELAMENTO_TIPO>
        <CANCELAMENTO_DATA>20/10/2016 18:44:58</CANCELAMENTO_DATA>
        <PROTOCOLOINDISPONIBILIDADE>31312313</PROTOCOLOINDISPONIBILIDADE>
        <DATAPEDIDO>02/07/2015 10:42:41</DATAPEDIDO>
        <NUMERODOPROCESSO>03720158260369</NUMERODOPROCESSO>
        <TELEFONE>11-11111111</TELEFONE>
        <NOMEINSTITUICAO>Nome da Instituicao</NOMEINSTITUICAO>
        <FORUMVARA>MONTE APRAZIVEL - CENTRAL -> 2 Oficio</FORUMVARA>
        <USUARIO>Usuario</USUARIO>
        <EMAIL>[email protected]</EMAIL>
        <CANCELAMENTO>
            <INDIVIDUO>
                <NOME>Nome de alguem</NOME>
                <CPFCNPJ>022.266.234-33</CPFCNPJ>
                <IMOVEIS>
                    <MATRICULA>1512</MATRICULA>
                    <MATRICULA>1680</MATRICULA>
                    <MATRICULA>1511</MATRICULA>
                    <MATRICULA>4698</MATRICULA>
                </IMOVEIS>
            </INDIVIDUO>
        </CANCELAMENTO>
    </REGISTRO>

所以我想在我的Postgresql里面的表中保存那个结构，我有问题在我的类列表中转换标签（我的数据库中有一个表要保存（但每个应该是我的数据库中的寄存器）表，Registro，cancelamento和Individuo工作正常。如果XML是这样的：

<IMOVEIS>
  <MATRICULA>1511</MATRICULA>
</IMOVEIS>
<IMOVEIS>
  <MATRICULA>1512</MATRICULA>
</IMOVEIS>
<IMOVEIS>
  <MATRICULA>1680</MATRICULA>
</IMOVEIS>
<IMOVEIS>
  <MATRICULA>4698</MATRICULA>
</IMOVEIS>

但我不能改变xml：/

我希望这个JAXB例子可以帮助你

    private Imovie imoveis;

    @XmlElement(name = "NOME")
