dom4j saxreader.read() 报诡异错误

用dom4j  saxreader 修改xml 节点内容

 

 

 
  c语言
  12
 
 
  c语言1
  13
 

 

SAXReader saxReader = new SAXReader();
  Document document = saxReader.read(Class3.class.getClassLoader().getResourceAsStream("note.xml"));
  ArrayList list = (ArrayList) document.selectNodes("//name");
  Iterator iterator = list.iterator();
  while(iterator.hasNext()){
   
  Element element= (Element)iterator.next();
  element.setText("xx");
  }
  try {
   XMLWriter xmlWriter=new XMLWriter(new FileWriter(new File("d://note.xml")));
   xmlWriter.write(document);
   xmlWriter.close();
  } catch (IOException e) {
   e.printStackTrace();
  }
  
 }

 

 

报以下错误

原因在于：xml 文件中的 file://c:/Dtds/catalog.dtd"> 干扰。因为这个路径不存在。

 

  可以把这个dtd 的引入删掉

 

问题最后解决了。
