RE: Extracting Unique element names and attributes fro

In XSLT 2.0 it's simply

distinct-values(//*/name())
distinct-values(//@*/name())

If you really need to do it with XSLT 1.0, eliminating duplicates is
essentially the same problem as grouping, and you can use the Muenchian
grouping approach.

The preceding-sibling grouping technique isn't going to work (a) because
your nodes are not siblings of each other, and (b) because it only works
where the grouping key is the string-value of the node, not where it is some
other function of the node (here, it's name). Muenchian grouping works for
any string-valued function of a node.
