Customising XML Output using Repeaters

[mbewers1]

I'm builing a webpage with a drop-down menu and an XML-generated output, the latter of which is generated by the asp:Repeater tool.

The ASP code looks like this:

<asp:Repeater ID="rptRssFeed2" OnItemDataBound="rptRssFeed_ItemDataBound2" runat="server" 
                    Visible="False">
    <ItemTemplate>
            <asp:Literal ID="litTitle2" OnLoad="litTitleCheck" runat="server"/><br />
            <asp:Literal ID="litDescription2" runat="server" /><br />
            <asp:HyperLink ID="hypLink2" Text="View" runat="server" />
    </ItemTemplate>
    <SeparatorTemplate>
        <hr />
    </SeparatorTemplate>
    </asp:Repeater>

Basically, I have a databse containing a list of academic papers (titles are shown on the drop-down menu) and associated keywords. Based on the paper selected by the user, I want to find a way of customising the RSS output so that it is reduced to showing only the news items containing the keywords from the user’s selected paper (e.g. containing the keywords ‘mobile’, ‘laptop’ or ‘interface’) and not any other news items which don’t contain any for these keywords.

Although the Repeater tools contain literals and hyperlinks, it's not possible to access these from the C# code page. It is only possible to access the repeater tool, which doesn't have a text property.

Is it possible to customise the output of a Repeater once it has been generated and, if so, how? Else, should I go about reading the XML file in a different way?
