    1. COThe question sounds more like laurentgnu wants to find the most deeply nested elements in an Xml document.

    2. COYes I need Xpath to show the most deeply nested elements and their direct ancestor. Anyway thank you @Martin for that XLST solution. But actually I need to use an xpath command **if possible**. Here is the xmltwig code I am using : `@abc=$t->get_xpath("\/\/[\@method]\/ancestor\:\:\*"); foreach my $v (@abc)` { # blabla }

    3. COWell you seem to want to reorganize the nodes by eliminating ancestors and by mapping each leaf to its parent, at least that is what I see in your posted result. As XPath does not allow you to do any manipulation of nodes but rather selects nodes in an existing documents I think you need more than XPath. Your comment's sample suggest you want to use some imperative host language and XPath but I don't recognize that language so I can not help with that. Tag your question with that language (e.g. Python, PHP), explain which XPath API you use, then people with experience in that area can help.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
