使用dom4j递归解析节点内还含有多个节点的xml

<xml>
    <ToUserName><![CDATA[toUser]]></ToUserName>
    <FromUserName><![CDATA[fromUser]]></FromUserName>
    <CreateTime>1348831860</CreateTime>
    <MsgType><![CDATA[text]]></MsgType>
    <Content><![CDATA[this is a test]]></Content>
    <MsgId>
        <ToUserName><![CDATA[1]]></ToUserName>
            <MsgId>
                <ToUserName><![CDATA[2]]></ToUserName>
                <ToUserName><![CDATA[3]]></ToUserName>
            </MsgId>
        <FromUserName><![CDATA[4]]></FromUserName>
    </MsgId>
</xml>
