解析会了,那接着来学学生成~
同样的引入依赖:
import java.io.File; import java.io.FileOutputStream; import org.dom4j.Document; import org.dom4j.DocumentHelper; import org.dom4j.Element; import org.dom4j.io.OutputFormat; import org.dom4j.io.XMLWriter;
注意处理异常:
public static void main(String[] args) throws Exception { }
创建树:
Document doc = DocumentHelper.createDocument(); //增加根节点 Element books = doc.addElement("books"); //增加子元素 Element book1 = books.addElement("book"); Element title1 = book1.addElement("title"); Element author1 = book1.addElement("author"); Element book2 = books.addElement("book"); Element title2 = book2.addElement("title"); Element author2 = book2.addElement("author");
为相应节点增加属性:
book1.addAttribute("id", "001"); title1.setText("Harry Potter"); author1.setText("J K. Rowling"); book2.addAttribute("id", "002"); title2.setText("Learning XML"); author2.setText("Erik T. Ray");
接下来是输出,设置编码,创建 File 对象:
OutputFormat format = OutputFormat.createPrettyPrint(); format.setEncoding("UTF-8"); File file = new File("writeBooks.xml");
根据创建的 File 对象,来生成 XMLWriter 对象:
XMLWriter writer = new XMLWriter(new FileOutputStream(file), format);
最后,将创建的 Document 对象写入 XMLWriter 对象:
writer.write(doc);
