    Xpath select all items where parent has specific nodename

    I'm always struggling to long with XPaths, now again:

    For a new  umbraco site i've got about 30 products.
    In my media library I sort it's images in subfolders of a folder with the name of the product.

    Product name
    -- Thumbnails
    -- HoverImages
    -- Backgrounds

    In my MNTP I want to add a filter based on it's parents nodeName.
    E.g.: only the images in the 'Backgrounds' may be picked.

    If I write: /*[@nodeName='Backgrounds'], the folder 'Backgrounds' can be picked.
    That right if I use my little XPath knowledge /*[ancestor::*[@nodeName='Backgrounds']] must be the code to get it's children be selectable. Sadly that's not right. What's wrong?

    Thanks in advance.

    Hi Gaitano,

    Unfortunately the XPath filters for enabling/disabling a node are only applied to that node itself (and not the entire tree). So you can test for properties on that node specifically, but can not traverse to parent/child nodes.

    You could use the @parentID? (Not as flexible as the parent's @nodeName, but could be a workable solution?)

    Cheers, Lee.

    Thx Lee, for clearing this out. 
    Like you say it yourself: that's nto really flexible.

    I think I'll add an extra property to my image: imageType and check on that.
    Too bad traversing through parents isn't possible.

    It might be possible, but would be quite a big hit on rendering each node on the tree, especially if the tree is large.

    Still *if* it is something you feel strongly about, do feel free to raise a ticket over on the issue tracker:

    You never know, others might feel the same and work towards a fix/resolution? :-)

    Cheers, Lee.
