解析XML在Java中

Question

屬性我有類似這樣

<Applications> 
    <ApplicationID> 
    <VendorId value="0" /> 
    <AuthApplId value="4" /> 
    <AcctApplId value="0" /> 
    </ApplicationID> 
    <ApplicationID> 
    <VendorId value="193" /> 
    <AuthApplId value="0" /> 
    <AcctApplId value="19302" /> 
    </ApplicationID> 
</Applications> 

我要分析此，並存儲爲字符串像廠商ID，AuthApplId等我的applicationID解析與getElementsByTagName("ApplicationID")如果它是一個XML <ApplicationID value="somevalue"/>那麼我就可以使用getAttribute("value")方法。但在上述情況下，我應該怎麼做？

Answer 1

NodeList applicationIDNodes = getElementsByTagName("ApplicationID"); 
for (int i = 0; i < applicationIDNodes.length; i++) { 
    Node applicationIDNode = applciationIdNodes.getItem(i); 
    NodeList applicationIdChildren = applicationIdNode.getChildren(); 

    String vendorId = applicationIdChildren.getItem(0).getAttribute("value").value(); 
    String authAppliId = applicationIdChildren.getItem(1).getAttribute("value").value(); 
    String actApplID = applicationIdChildren.getItem(2).getAttribute("value").value(); 

    // do whathever you want with vendorId, authAppliId, actApplID  
}
