Hi,

I'm trying to use the XMLDataSource and DataList controls in Visual Web
Developer Express (VB.Net) to present the following rss file in a web
application. The problem lies in that I want to just select items (title,
description and link) that are in the 'april' category. Can anyone help me
with an XPath expression (or another way) of achieving this?

Thanks.

The following XPath expression returns the elements you need in a
nodeset result:

/rss/channel/item/pubDate[contains(.,"Apr")]/preceding-sibling::*
