[jdom-interest] Finding XPath location for an Element

[Rolf Lear]

Yes, you could do that and get an exact path to a particular element....

I had not thought it through as far as you, but the indexing is reasonable
(so is 'season to taste')....

But then you should probably also take it further again and ensure that
the namespace management is correct too....

but how would you set up the XPath references/links for an XPath query
with namespaces ... easily ... and in a 'general' way?
