Replicate Multiple RSS Accounts

Replicate multiple RSS accounts to one or many databases.

CData Sync for RSS is a stand-alone application that provides solutions for a variety of replication scenarios such as replicating sandbox and production instances into your database. Both Sync for Windows and Sync for Java include a command-line interface (CLI) that makes it easy to manage multiple RSS connections. In this article we show how to use the CLI to replicate multiple RSS accounts.

Configure RSS Connections

You can save connection and email notification settings in an XML configuration file. To replicate multiple RSS accounts, use multiple configuration files. Below is an example configuration to replicate RSS to SQLite:

Windows

<?xml version="1.0" encoding="UTF-8" ?> <CDataSync> <DatabaseType>SQLite</DatabaseType> <DatabaseProvider>System.Data.SQLite</DatabaseProvider> <ConnectionString>URL=http://broadcastCorp/rss/;</ConnectionString> <ReplicateAll>False</ReplicateAll> <NotificationUserName></NotificationUserName> <DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString> <TaskSchedulerStartTime>09:51</TaskSchedulerStartTime> <TaskSchedulerInterval>Never</TaskSchedulerInterval> </CDataSync>

Java

<?xml version="1.0" encoding="UTF-8" ?> <CDataSync> <DatabaseType>SQLite</DatabaseType> <DatabaseProvider>org.sqlite.JDBC</DatabaseProvider> <ConnectionString>URL=http://broadcastCorp/rss/;</ConnectionString> <ReplicateAll>False</ReplicateAll> <NotificationUserName></NotificationUserName> <DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString> </CDataSync>

You can connect to RSS and Atom feeds, as well as feeds with custom extensions. To connect to a feed, set the URL property. You can also access secure feeds. A variety of authentication mechanisms are supported. See the help documentation for details.

Configure Queries for Each RSS Instance

Sync enables you to control replication with standard SQL. The REPLICATE statement is a high-level command that caches and maintains a table in your database. You can define any SELECT query supported by the RSS API. The statement below caches and incrementally updates a table of RSS feeds:

REPLICATE Latest News;

You can specify a file containing the replication queries you want to use to update a particular database. Separate replication statements with semicolons. The following options are useful if you are replicating multiple RSS accounts into the same database:

You can use a different table prefix in the REPLICATE SELECT statement:

REPLICATE PROD_Latest News SELECT * FROM Latest News

Alternatively, you can use a different schema:

REPLICATE PROD.Latest News SELECT * FROM Latest News

Run Sync

After you have configured the connection strings and replication queries, you can run Sync with the following command-line options:

Windows

RSSSync.exe -g MyProductionRSSConfig.xml -f MyProductionRSSSync.sql

Java

java -Xbootclasspath/p:c:\sqlitejdbc.jar -jar RSSSync.jar -g MyProductionRSSConfig.xml -f MyProductionRSSSync.sql
