Re: XSLT test on the name of a node

A [...] is a predicate. Everything in a predicate refers to the node which
belongs to the predicate:

node[name() = @attr]   (a node, whose name is the same as the value of the
attr; so it's true for <node attr="node"/>)

In your case it was the same. You selected all nodes, whose local name is
the same as the value of their ld-tag attribute: <node ld-tag="node"/> for
example. With current() you change back to the context-node (on which the
template matches). Otherwise local-name() would give you back the local-name
of the matched node too, and not of the node you want to select.

$language/node()[local-name() = current()/@ld-tag]

Hope this helps,

Joerg
