特性

• RSSpect能夠很方便讀寫RSS新聞源
• 擁有直觀，開發友好的API
• 在類庫中的對象都是序列化，不可改變的和線程安全。
• Fully tested for accuracy (See the distributed test-sources.jar for reference).
• Minimal dependencies. RSSpect only requires a stax-api implementation to work.
• In the spirit of Open Source Software, RSSpect is licensed with the terms of the Apache License, Version 2.0.

示例

• 從本地硬盤的一個XML文件生成一個RSS bean.
  

  RSS myRSS = new RSSDoc().readRSSToBean(new File("/myPath/myRSS.xml");

  </li>

• 從Web的一個XML文件生成一個RSS bean

  RSS myRSS = new RSSDoc().readRSSToBean(new URL("http://www.abcdefg.net/myRSS.xml");

• Read an RSS bean into a String.
  

  String myRssStr = myRSS.toString();

  </li>

• Read an RSS bean into a formatted String.
  

  String myRssStr = new RSSDoc().readRSSToString(myRSS, "javanet.staxutils.IndentingXMLStreamWriter");

  </li>

• Write an RSS bean to disk.
  

  new RSSDoc().writeRSSDoc(new File("/somewhere/myRSS.xml"), myRSS, "UTF-8", "1.0");

  </li>

• Write a formatted RSS bean to disk.
  

  new RSSDoc().writeRSSDoc(new javanet.staxutils.IndentingXMLStreamWriter( XMLOutputFactory.newInstance().createXMLStreamWriter( new FileOutputStream("/somewhere/myRSS.xml"), "UTF-8")), myRSS, "UTF-8", "1.0");

  </li>

• 一個CRUD（增/刪/改/查）示例：

  public class CrudExample {
  
  
  public static void main(String[] args) {
      try {
          RSSDoc rssDoc = new RSSDoc();
  
          // make sure title or description is present for item
          Title title = rssDoc.buildTitle("my title");
          Description description = rssDoc.buildDescription("my description");
          Item item = rssDoc.buildItem(title, null, description, null, null,
                  null, null, null, null, null, null);
  
          // title, link and description are required for channel
          // we add pubDate and items because these are usually there
          Link link = rssDoc
                  .buildLink("http://www.colorfulsoftware.com/projects/rsspect");
          List items = new ArrayList();
