RE: How do I locate the parent of this node?

Thanks for the suggestion, Joerg. I'm not clear about the syntax, though.
Should it look like this?...

parent::$currentNode

or something else? I guess my basic difficulty is that I'm not sure, having
passed the parameter $currentNode into the template, how to get $currentNode
as the context node in order to find its parent. Or am I missing something
obvious here?

simply use ".." or "parent::XMLDataItem".

Help, please! 

For the XML data structure below I'm trying to use a recursive template to
piece together the 'path' of each XMLDataItem element. Thus for the
XMLDataItem whose @Name is 'POIssuedDate' I want the template to return

the

path as '/bat:Batch/PurchaseOrder/OrderHeader'

To do this I need an XPath statement inside the template to locate the
parent node of the current node. I've been using...

//XMLDataItem[child::XMLDataItem/@Name=$currentNode/@Name]

(where $currentNode is the parameter passed into the template). However,
it's not finding that parent node - actually, in this instance it's not
finding anything. Any suggestions?
