<inputs>
<MAT_NO>123</MAT_NO>
<MAT_NO>323</MAT_NO>
<MAT_NO>4223</MAT_NO>
<FOO_BAR>122</FOO_BAR>
<FOO_BAR>125</FOO_BAR>
</inputs>
我必須解析上面的XML。解析後,我希望這些值是在Map<String, List<String>>
對應於子節點的鍵值 - MAT_NO,foo_bar這樣 價值觀和 - 孩子的價值觀節點-123,323等解析XML並轉換爲集合
以下是我的投籃。有沒有更好的方式做到這一點?

節點的孩子是動態的。我會知道只有根節點。
嗨史蒂文,對不起,我剛剛更新了這個問題。輸入的子節點是動態的 – HanuAthena 2010-10-11 07:45:27
