    Xpath Expression Filter - Why cant i see any nodes? iD10T error

    Hi

    I am new to xpath. I am trying to use the "nuPickers XML Dropdown picker" on Umbraco 7.3.4

    but no matter what xpath xpression filter i use, the dropdown remains empty no nodes is being loaded in to the dropdown

    i tried the following filters:

    $root/

    $site/

    /*/

    $ancestor-or-self::Home/

    but to no avail, none of them loads any nodes

    i actually want to select all the "Club" nodes under "Clubcontainer", but i cant get it to load any nodes, nevermind the specific ones that i actually want. My Umbraco.config looks as follows: (some nodes removed under to only show relevant nodes for my filter query.)

    <root id="-1">

    Hi Gerrie

    Some pretty good examples of how the Xpath can be written here:

    https://github.com/uComponents/nuPickers/wiki/Data-Source-Xml

    so

    //Club

    would return 'all' club nodes in your site.

    and I think...

    $ancestorOrSelf/ancestor-or-self::Home[position()=1]//Clubcontainer//Club

    would be close to what you are after...
