How to display only the <system-page> node for the current page?

I have three pages named page1, page2, and page2.

I also have a long index block full of pages that is structured like this:

   <system-page id="1">
        <content>Some content</content> 
   <system-page id="2">
        <content>Some content</content> 
   <system-page id="3">
        <content>Some content</content> 
</system-index block>

I am trying to print only the information inside <system-page id="3"></system-page> onto a page. However, I don't want to hardcode the system-page id. I'd like to write a format that will work for ANY system-page id (I'd like to write one format that would only print page2's data when I'm on page2, or only page1's data when I'm on page1.) How do I go about doing this?

Additional info: - Users will get to the page that ONLY contains information from a single specific <system-page> node by clicking a link set to the value of <path> (for example,) <a href="$system-page.getChild('path').value">Link</a>). Is that useful at all?

    I mean, I have three pages named exhibit1, exhibit2, exhibit3.

    The page names are the name as <system-page><name></name></system-page>

    I'm sorry for that mistake, I can't see where to edit my original question.

    Hi Eric,

    Displaying the content for the current page can be done a in a few ways.

    If you would like to use your current Index Block, you can filter the pages using the current attribute that is added to the <system-page> that is currently being viewed (ie the context page):

    #set ( $currentPage = $_XPathTool.selectSingleNode($contentRoot, "/system-index-block/system-page[@current]") )

    Alternatively, if all you want to do is output the content of the current page and nothing else, I would recommend using a calling page Index Block, which will only include the calling page's content and nothing else. This is generally more efficient than including a large Index Block. If you go this route, your Velocity would differ slightly:

    #set ( $currentPage = $_XPathTool.selectSingleNode($contentRoot, "/system-index-block/calling-page/system-page[@current]") )

    Also, I wanted to note that if you are running Cascade Server 7.10.1 or newer, Velocity Formats have access to a global $currentPage variable, which will be the calling page object. Slightly different than obtaining the page using the XPath Tool, but could help simplify things a bit. To view the properties of the $currentPage variable, you can use the following:


    Please let me know if you have any questions.
