这是我的XML文件。
<config> <properties>
<entry key="delivaryDate">15-FEBRUARY-2013</entry>
<entry key="externalCOID">123456</entry>
<entry key="inputFileName">Generic_ChipONLY.chp</entry>
<entry key="recordTotal">2</entry>
<entry key="dueDate">15-MARCH-2013</entry>
</properties> </config>
例如,我想将“recordTotal”中的记录从2更改为10,我该怎么做? 现在我只知道使用getElementsByTagName(“entry”)。
DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
Document doc = docBuilder.parse(new File("customer.xml"));
NodeList entry = doc.getElementsByTagName("entry");
答案 0 :(得分:0)
String xmlFile = "customer.xml";
DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
Document doc = docBuilder.parse(xmlFile);
//Retrieve the third entry node
Node entryNode = doc.getElementsByTagName("entry").item(3);
//Set new value
entryNode.setTextContent("10");
//Save to file
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
DOMSource source = new DOMSource(doc);
StreamResult result = new StreamResult(new File(xmlFile));
transformer.transform(source, result);
