- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
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
<?xml version="1.0" encoding="utf-8" standalone="yes"?>

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
最佳答案
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"
// ...
}
