您可以使用包含在 Java SE 6 及更高版本中的 StAX API 来创建您的 XML 文档：

XMLOutputFactory xof = XMLOutputFactory.newFactory();
XMLStreamWriter xsr = xof.createXMLStreamWriter(System.out);
xsw.writeStartDocument();
xsw.writeStartElement("courses");
xsw.writeStartElement("course");
xsw.writeAttribute("number", " CIS 101");
xsw.writeStartElement("title");
xsw.writeCharacters("Personal Computing");
xsw.writeEndElement();  // </title>
...
xsw.writeEndElement(); // </course>
xsw.writeEndElement(); // </courses>
xsw.writeEndDocument();
