Java 使用NodeList和DocumentBuilder解析Xml

使用dom和DocumentBuilder解析xml有点困难。我可以让它工作，但我想我对所有的子节点都有点困惑，等等

下面是我正在使用的XML：

我试图做的是抓住每个

LabTest

元素，在每个元素中抓住

value

元素（抓住

type

的值），在

value

元素中抓住所有

条件

元素

最后，我想要一个像

Map这样的东西，它应该像您描述的那样工作：

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();

Document doc = builder.parse("input.xml");

NodeList labTestList = doc.getElementsByTagName("LabTest");
for (int i = 0; i < labTestList.getLength(); ++i)
{
    Element labTest = (Element) labTestList.item(i);
    String labTestType = labTest.getAttribute("type");

    NodeList valueList = labTest.getElementsByTagName("value");
    for (int j = 0; j < valueList.getLength(); ++j)
    {
        Element value = (Element) valueList.item(j);
        String valueType = value.getAttribute("type");

        NodeList conditionList = value.getElementsByTagName("condition");
        for (int k = 0; k < conditionList.getLength(); ++k)
        {
            Element condition = (Element) conditionList.item(k);
            String conditionText = condition.getFirstChild().getNodeValue();
        }
    }
}

DocumentBuilderFactory=DocumentBuilderFactory.newInstance（）；
DocumentBuilder=factory.newDocumentBuilder（）；
documentdoc=builder.parse（“input.xml”）；
NodeList labTestList=doc.getElementsByTagName（“LabTest”）；
对于（int i=0；i
非常感谢您。这太棒了！！
