Hi,

I try to get the deepest "Name" element and vlaue (Sport & Freizeit in this case), but it does not work with xpath():

$temp=$item->xpath("//Name[last()]");

I guess I don't understand how xpath() works..

Does anybody has a hint? The number of "BrowseNode" elements is flexible, so I can't work with a fix path.

THX!

You have to wrap the //Name tag and then get the last item.

(//Name)[last()]
