Read RSS using ROME ( sample code )

ROME is an open source tool to parse, generate and publish RSS and Atom feeds. Using Rome you can parse the available RSS and Atom feeds. Without bothering about format and version of RSS feed. The core library depends on the JDOM XML parser.
Considering you have all the required jar files we will start with reading the RSS feed. ROME represents syndication feeds (RSS and Atom) as instances of the com.sun.syndication.synd.SyndFeed interface. This library can be downloaded from here.

ROME includes parsers to process syndication feeds into SyndFeed instances. The SyndFeedInput class handles the parsers using the correct one based on the syndication feed being processed. The developer does not need to worry about selecting the right parser for a syndication feed, the SyndFeedInput will take care of it by peeking at the syndication feed structure.
A sample java code can be described as follows:

package com.infosys.hanumant.rome;

import java.net.URL;
import java.util.Iterator;

import com.sun.syndication.feed.synd.SyndEntry;
import com.sun.syndication.feed.synd.SyndFeed;
import com.sun.syndication.io.SyndFeedInput;
import com.sun.syndication.io.XmlReader;

/**
* @author Hanumant Shikhare
*/
public class Reader {

public static void main(String[] args) throws Exception {

URL url = new URL("http://viralpatel.net/blogs/feed");
XmlReader reader = null;

try {

reader = new XmlReader(url);
SyndFeed feed = new SyndFeedInput().build(reader);
System.out.println("Feed Title: "+ feed.getAuthor());

for (Iterator i = feed.getEntries().iterator(); i.hasNext();) {
SyndEntry entry = (SyndEntry) i.next();
System.out.println(entry.getTitle());
}
} finally {
if (reader != null)
reader.close();
}
}
}

email to rss

How to convert an email message to a RSS feed. But again we need to think why we are doing this. This will be the easiest way to publish many ideas of different people into a one single site, or many of them.

In the web there are some systems available like MailBucket. And these are some gateways which converts email messages to a RSS feed.

But if you check in Google Groups, it will give you a faster and easy way to convert all the mails which are going inside the group emails.
