在线等......dom 转换 xml
需求,给order.xml 中的节点RCPTNO赋值
order.xml 如下:
<?xml version="1.0" encoding="UTF-8"?>
<TRANSACTIONS>
<TRANSACTION>
<RCPTNO></RCPTNO>
</TRANSACTION>
</TRANSACTIONS>
java 代码:
public static void main(String[] args) throws Exception {
//xml转化成 dom
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document doc = builder.parse("order.xml");
doc.normalize();
String s = "Hello";
Text textseg = doc.createTextNode(s);
doc.getElementsByTagName("RCPTNO").item(0).appendChild(textseg);
//dom文档 转化成 xml
TransformerFactory tFactory = TransformerFactory.newInstance();
Transformer transformer = tFactory.newTransformer();
DOMSource source = new DOMSource(doc);
StreamResult result = new StreamResult(new File("order.xml"));
transformer.transform(source, result);
}
所报异常:
Exception in thread "main" java.lang.AbstractMethodError: org.apache.xerces.dom.DeferredDocumentImpl.getXmlStandalone()Z

In case anyone else gets this error - I fixed it by removing
xerces.jar and replacing it with xercesImpl.jar.

你的结帖率太低了

2楼说了I fixed it by removing
xerces.jar and replacing it with xercesImpl.jar
替换一下看看吧 ，应该是使用了没有实现的抽象类的方法了
