dom4j 复制xml文件/复制xml文件中选中节点到另一个xml文件

1、xml文件复制：

public void copyXml(String sourcefile,String destfile){

try {

File source = new File(sourcefile);

if(source.exists() && source.isFile()){

File dest=new File(destfile);

if(dest.exists()){

dest.delete();

}

dest.createNewFile();

SAXReader saxReader=new SAXReader();

Document document=saxReader.read(source);

FileOutputStream outputStream=new FileOutputStream(destfile);

//漂浪格式，有格式，有空格

OutputFormat format=OutputFormat.createPrettyPrint();

//紧凑格式，无空格换行

//OutputFormat format=OutputFormat.createCompactFormat();

format.setEncoding("UTF-8");

XMLWriter writer=new XMLWriter(outputStream, format);

writer.write(document);

writer.close();

}

} catch (Exception e) {

// TODO Auto-generated catch block

System.out.println("xml文件拷贝异常");

e.printStackTrace();

}

}

调用：

copyXml("C:/test.xml", "C:/test_cp.xml");

2、xml文件拷贝一个xml中某个节点到另一个xml文件

public void copyNodeToOther(){

//目标xml文件

File resxmlfile=new File("C:\\Users\\Administrator\\Desktop\\test\\test.xml");

SAXReader reader2=new SAXReader();

Document document2=reader2.read(resxmlfile);

Element root2= document2.getRootElement();

//源xml文件

File batfile=new File("C:\\Users\\Administrator\\Desktop\\test\\test_bat.xml");

SAXReader reader=new SAXReader();

Document document=reader.read(batfile);

Element root= document.getRootElement();

List<Element> scenelist=root.elements("scene");

for(Element scenenode:scenelist){

System.out.println("节点名称："+scenenode.getName());

Attribute attribute=scenenode.attribute("title");

System.out.println(attribute.getName());

System.out.println(attribute.getNodeTypeName());

System.out.println(attribute.getValue());

System.out.println(attribute.getQName());

String val=attribute.getValue();

if(val.startsWith("111_")){

Element sceneClone=(Element) scenenode.clone();

root2.add(sceneClone);

}

}

FileOutputStream outputStream=new FileOutputStream(resxmlfile);

OutputFormat format=OutputFormat.createPrettyPrint();

format.setEncoding("UTF-8");

XMLWriter writer=new XMLWriter(outputStream, format);

writer.write(document);

writer.close();

}
