我需要解析 XML，下面给出了 XML 的某些部分:
<?xml version="1.0" encoding="utf-8"?>

我需要阅读此内容并以所需的 XML 格式编写此内容。 我的代码如下:
public static void main(String[] args) throws SAXException, IOException,ParserConfigurationException, TransformerException
{
DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
Document document = docBuilder.parse(new File("C:/Users/ve00p5199/Desktop/Axure.xml"));
NodeList nodeList = document.getElementsByTagName("*");
System.out.println("total nodes="+nodeList.getLength());
for (int i = 0; i < nodeList.getLength(); i++) {
Node node = nodeList.item(i);
if(node.getNodeType() != Node.ELEMENT_NODE){
System.out.print(node.getNodeName()+"= ");
System.out.println(node.getTextContent());
}
else if (node.getNodeType() == Node.ELEMENT_NODE) {
// do something with the current element
System.out.print(node.getNodeName()+"= ");
System.out.println(((Node) node.getChildNodes()).getNodeValue()); //giving NULL
System.out.println(node.getNodeValue());//giving NULL
}
}
}
}
我想打印标签及其值。请建议保存/打印标签名称及其值所需的方法。
最佳答案
您需要使用以下两个函数来获取标记名及其文本内容 -
tag = ((Element)Node).getTagName() //or you can also use Node.getNodeName()
textValue = Node.getTextContent()
如果您不需要后代的文本内容，则必须获取每个节点的子节点并过滤掉类型为 Node.TEXT_NODE 的节点，然后打印 textContent 仅适用于 TEXT_NODE 。
示例 -
else if (node.getNodeType() == Node.ELEMENT_NODE) {
// do something with the current element
System.out.print(node.getNodeName()+"= ");
NodeList cNodes = node.getChildNodes();
for(int j = 0;j< cNodes.getLength();j++) {
Node cN = cNodes.item(j);
if(cN.getNodeType() == Node.TEXT_NODE) {
System.out.println(cN.getTextContent());
}
}
}
请注意，这也会提供大量仅包含换行符和内容的文本内容，您可以根据需要添加自己的额外代码来过滤掉它们。
关于java - 使用java解析xml(w3.org)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/31107580/
