WINDEV, WEBDEV and WINDEV Mobile allow you to produce and/or consume an RSS stream (Rapid Simple Syndication).
An RSS stream is used to produce (make available) a data stream in standard format. This data stream can be read (consumed) by an application.
A reader of RSS stream is used to display one or more RSS streams.
How to proceed?

Creating an RSS stream

To create an RSS stream:
  1. Declare the rssStream, rssChannel and rssEntry variables.
  2. Describe the channel with the rssChannel properties.
  3. Describe the entries with the rssEntry properties.
  4. Add the channel then its entries into the stream.
  • A stream is made of channels. A channel is made of entries.
  • We recommend that you use functions such as Add, Delete, … to handle the array of entries and the array of channels.


Example for creating a RSS stream:
MyStream is rssStream
MyChannel is rssChannel
MyEntry is rssEntry
MyPath is string
// Characteristics of channel
MyChannel..Title = "My site"
MyChannel..Description = "Example of RSS 2.0 stream"
MyChannel..UpdateDate = DateSys() + TimeSys()
MyChannel..Link = "http://www.example.org"
// Characteristics of entries of channel 1
MyEntry..Author = "pcsoft@pcsoft.fr"
MyEntry..Description = "First news"
MyEntry..Title = "News #1"
// Adds the entry into the channel
Add(MyChannel..Entry, MyEntry)
// Adds the channel into the stream
Add(MyStream..Channel, MyChannel)
// Saves the stream in a file
MyPath = CompleteDir(fCurrentDir()) + "Rss.xml"
rssSave(MyStream, MyPath)
// Displays the XML file of stream
IF NOT ShellExecute(MyPath) THEN
Error("ShellExecute('" + MyPath + "'). '" + ErrorInfo() + "'")
Caution: In this example, the additions performed by Add must be performed last to handle the requested element. You also have the ability to use the following code:
MyStream is rssStream
ChannelNum is int
EntryNum is int
MyPath is string
MyPath = CompleteDir(fCurrentDir()) + "Rss.xml"
// Describe and add the channel
ChannelNum = 1
ChannelNum = Add(MyStream..Channel)
MyStream..Channel[ChannelNum]..Title = "My site"
MyStream..Channel[ChannelNum]..Description = "Example of RSS 2.0 stream"
MyStream..Channel[ChannelNum]..PublicationDate = Today()
MyStream..Channel[ChannelNum]..Link = "http://www.example.org"
// Describe and add the entry 1
EntryNum = Add(MyStream.Channel[ChannelNum]..Entry)
MyStream..Channel[ChannelNum]..Entry[EntryNum]..Title = "First news"
MyStream..Channel[ChannelNum]..Entry[EntryNum]..Description = "News #1"
MyStream..Channel[ChannelNum]..Entry[EntryNum]..Link = "http://www.example.org"
MyStream.Channel[ChannelNum]..Entry[EntryNum]..PublicationDate = Today()
EntryNum = Add(MyStream..Channel[ChannelNum]..Entry)
// Describe and add the next entry
MyEntry is dynamic rssEntry = MyStream..Channel[ChannelNum]..Entry[EntryNum]
MyEntry..Title = "Second news"
MyEntry..Description = "News #2"
MyEntry..Link = "http://www.example.org"
MyEntry..PublicationDate = Today()
// Saves the stream in a file
rssSave(MyStream, MyPath)
// Displays the XML file of stream
IF NOT ShellExecute(MyPath) THEN
Error("ShellExecute('" + MyPath + "'). '" + ErrorInfo() + "'")

These functions are used to read and create a stream.
These functions can be handled by specific types of variables: rssStream, rssChannel,...
