java - 需要使用 java 从 xml 中提取特定标签及其值

Question

大家好，我是 Java 新手 需要从 xml 中提取标签及其值

代码:

Document doc = loadXml("data.xml");  
NodeList nodeList = doc.getElementsByTagName("CreateResponse");  
for (int i = 0; i < nodeList.getLength(); i++) {  
    Node node = nodeList.item(i);  
    if (node.getNodeType() == Node.ELEMENT_NODE) {  
        Element element = (Element) node;  
        NodeList ROWList = element.getElementsByTagName("Row");  
        Element weekElement = (Element) RowList.item(0);  
        NodeList textElementList = weekElement.getChildNodes();
        System.out.println("Row:"+((Node)textElementList.item(0)).getNodeValue().trim());
}

下面是我的输入

我需要提取一个仅包含所需标签及其值示例的 xml

             <Slot>XXXXX</Slot><Shelf>yyyy</Shelf>

我尝试使用一位 friend 建议的以下代码，但它没有达到我的目的

Answer 1

尝试使用 XPath:

XPathExpression expr = xpath.compile("//*[self::Slot or self::Shelf]");
NodeList nodeList = (NodeList) expr.evaluate(doc, XPathConstants.NODESET);
for (int i=0; i<nodeList.getLength(); i++) {
  Node node = nodeList.item(i);
  node.getLocalName(); // The element name, e.g. "Slot"
  node.getTextContent(); // The element text content, e.g. "XXXXX"
  // ...
}
