Java读取xml文件里属性

需要解析的xml文件

<Data>
       <ElemName caption="lalalala">
           <Color>
            <Value caption="0"/>
            <Value caption="0"/>
            <Value caption="0"/>
        </Color>
        <Level caption="888">
            <MinValue caption="0"/>
            <MaxValue caption="360"/>
            <Interval caption="60"/>
        </Level>
    </ElemName>
<Data>
