The above example is for demonstration only, real-life applications usually contain many more item elements.
■ theoretically, an rSS channel can contain an arbitrary number of items. however, some rSS readers (such as the
news feed reader gadget in Windows Vista and Windows 7) do not support rSS files larger than approximately 150Kb or
2,800 lines, which corresponds to approximately 7 months of daily news. it is recommended that you keep the file size
under this limit to maximize interoperability.
Some of the presented elements are required, while others are optional but highly recommended. First we'll
examine the required elements.
As shown in the previous section, the rss element contains the channel element with all its contents. The required
elements of the channel element in RSS 2.0 are title , link , and description .
The title Element
The title element represents the name of the channel. It often coincides with the title of the web site it is associated
with. Listing 8-2 shows an example.

The link element is a URI representing the domain where the news feed is located. Listing 8-3 shows an example.
