使用.

示例

private String writeXml(List<Message> messages){
    XmlSerializer serializer = Xml.newSerializer();
    StringWriter writer = new StringWriter();
    try {
        serializer.setOutput(writer);
        serializer.startDocument("UTF-8", true);
        serializer.startTag("", "messages");
        serializer.attribute("", "number", String.valueOf(messages.size()));
        for (Message msg: messages){
            serializer.startTag("", "message");
            serializer.attribute("", "date", msg.getDate());
            serializer.startTag("", "title");
            serializer.text(msg.getTitle());
            serializer.endTag("", "title");
            serializer.startTag("", "url");
            serializer.text(msg.getLink().toExternalForm());
            serializer.endTag("", "url");
            serializer.startTag("", "body");
            serializer.text(msg.getDescription());
            serializer.endTag("", "body");
            serializer.endTag("", "message");
        }
        serializer.endTag("", "messages");
        serializer.endDocument();
        return writer.toString();
    } catch (Exception e) {
        throw new RuntimeException(e);
    }
}
