最佳的DataStructure，用于在Engine启动时存储XML重复结构

Question

我是Spring的新手，想知道在引擎启动时存储重复结构的最佳方法是什么。

XML看起来像这样：

<?xml version = "1.0" encoding = "UTF-8"?>
<root>
    <OSNDetails>
        <Processor>IPL</Processor>
        <AddDataOSNs>AUTHORIZED</AddDataOSNs>
        <APIList>
            <confirmpayin>
                <osnlistwithDelay>AUTHORIZED:0,CAPTURED:10,SETTLED:15</osnlistwithDelay>
            </confirmpayin>
            <confirmrejected>
                <osnlistwithDelay>CONFIRMREJECTED:0</osnlistwithDelay>
            </confirmrejected>
            <confirmsettled>
                <osnlistwithDelay></osnlistwithDelay>
            </confirmsettled>
            <confirmrefund>
                <osnlistwithDelay>REFUNDED:0</osnlistwithDelay>
            </confirmrefund>
        </APIList>
    </OSNDetails>
    <OSNDetails>
        <Processor>ABC</Processor>
        <AddDataOSNs>AUTHORIZED,REFUNDED,CONFIRMREJECTED,SETTLED</AddDataOSNs>
        <APIList>
            <confirmpayin>
                <osnlistwithDelay>AUTHORIZED:0,CAPTURED:5</osnlistwithDelay>
            </confirmpayin>
            <confirmrejected>
                <osnlistwithDelay>CONFIRMREJECTED:0</osnlistwithDelay>
            </confirmrejected>
            <confirmsettled>
                <osnlistwithDelay>SETTLED:0</osnlistwithDelay>
            </confirmsettled>
            <confirmrefund>
                <osnlistwithDelay>REFUNDED:0</osnlistwithDelay>
            </confirmrefund>
        </APIList>
    </OSNDetails>
</root>

存储重复元素结构的最佳数据结构是什么，以及在以后处理实际事务时如何使用它。
