Hi there,

I have implemented asp.net adrotator control for rotating advertisements with xml file.

I am filtering specific advertisements with Keyword using 1 in xml for displaying advertisements.

I need to customize my filter with multiple keywords, so my filtration would be something like this 1 or 2. How can i do this?

Please provide some solution to filter multiple element keyword in xml file.
