    Using A Parent Picker with XML / Content Picker

    Is there any way to allow the selection of content available in an xml list, selected by XPath, to be chosen via a picker in the parent?

    So my tree structure would be like:

    • HOME

      +- FOLDER (doc prop: pickFolder < allows selection of a meta folder folder)

      +-- PAGE (doc prop: selector <- list of item1-3 from the meta folder selected above)

      +- META FOLDER

      +-- ANOTHER FOLDER (this one is picked above)

      +---- ITEM1

      +---- ITEM2

      +---- ITEM3

    Hey John,

    I think this is possible using xpath in a mntp, as long as you aren't expecting a multi-node tree picker to have multiple starting nodes.

    So the mntp located within PAGE called selector would need an xpath similar to

    $root/*[id=./pickFolder/text()]
    

    Hope this helps

    The man's a genius!

    I was trying to think how you'd inflate the XML using some kind of library call, but that is so simple, can't wait to try it.

    Hi John,

    I just tried this (saw on twitter that you're using nuPickers) - I created this structure:

    enter image description here

    Then I created the pickFolder property as an XML Prefetch List with this XPath:

    $ancestorOrSelf/ancestor::HOME_ALIAS/META_FOLDER_ALIAS/ANOTHER_FOLDER_ALIAS

    I created the selector property, also as an XML Prefetch List, with this XPath:

    $ancestorOrSelf/ancestor::HOME_ALIAS//*[@id = $ancestorOrSelf/ancestor-or-self::FOLDER_ALIAS/pickFolder//@Key]/ITEM_ALIAS

    (XPaths get a little muddy when you have to use the $ancestorOrSelf token first to be sure you have a published node to base the rest upon).

    Let me know if you need me to explain what's going on, or if I've misunderstood anything.
